1-1 Overview
Sony was one of the first to apply DAT technology to PCM data recorders. With the PC204A/208A, Sony condensed its numerous new technologies in a unit and introduced the DAT double speed recording/playback to the world.
The PC216A is the world's smallest and lightest 16-channel data recorder (A4 size, approximately 4.5 kg), based on high performance and efficiency of PC204A/208A.
Simultaneous recording up to 32 channels' data has been realized by using a channel expansion unit PCCX32.
Moreover, in the sync mode, simultaneous recording is possible up to 32 channels with two PC216As and up to 64 channels with PC216A and PCCX32. The PC216A can also serve as a stand-alone digital data recorder with high speed serial digital data I/O in addition to the parallel digital data output and the digital I/O channel using LSB.
In addition to its excellent performance in field-use, the PC216A can serve for a wide variety of use in measurement field.
1-2 Principal Features
World's Smallest Model of 16 Channels
The PC216A became the world's smallest and lightest 16-channel data recorder (A4 size, approximately 4.5 kg) by using the DAT second generation technologies including highly reliable mechanism and large-scale integrated electronics.
32-Channel Data Recording
The channel expansion unit PCCX32 allows the simultaneous data recording and playbak up to 32 channels at maximum.
Multiple B/C Mode
Multiple band/channel mode capable of 2-channel*, 4-channel, 8-channel, 16channel, or 32-channel recording/playback is provided. (32-channel mode is available only when the PCCX32 is used.) *Normal speed only In addition to regular recording/playback, the PC216A can play back the data recorded on a conventional audio DAT recorder using 2-channel/48 kHz
sampling.
Synchronizing Mode
By synchronizing two PC216As, simultaneous 32-channel data recording is enabled in 16-channel frequency band. By synchronizing two PC216As with PCCX32s, simultaneous 64-channel data recording is also enabled in 32-channel frequency band.
Doubled Frequency Band in DAT System
In previous DAT systems, the total bandwidth provided by all channels was 40 kHz. This unit possesses an 80 kHz band in the double speed mode, as the tape speed and drum rotation have been doubled.
The PC216A provides up to 5 kHz for each of 16 channels, and up to 2.5 kHz for each of 32 channels.
Variable Time Axis
Playing back at the double speed a tape recorded at the normal speed reduces the playback time by half. Alternatively, playing back at the normal speed a tape recorded at the double speed allows desired phenomena in the data to be reproduced at a slower rate.
Increased Recording Time
A new tape mechanism developed for thin DDS (Digital Data Storage) tapes, enables a recording time of 180 minutes (normal speed) or 90 minutes (double speed).
Digital Data Input/Output
The recording mode can be either Analog Mode (analog input/output) or Digital Mode (digital input/output).
• In Analog mode, the output of the parallel digital data and the input and output of the LSB digital data are available besides the input and output of the main analog data.
The data input in analog can be output in a 16-bit parallel digital data format. The input and output of the LSB digital data is available for one channel by utilizing the Least Significant Bit (LSB) of each digital word, which facilitates the recording of binary signals such as rotation pulses and timing signals.
• In Digital Mode, input and output of the serial bit stream is possible. The transfer rate in sync mode is 1.536 Mbps (normal speed) or 3.072 Mbps (double speed).
LSB Channel
In addition to the analog main data channels, digital input/output is available by utilizing the Least Significant Bit (LSB) of each digital data word. The LSB channel facilitates the recording of binary signals such as rotation pulses and timing signals.
Multiple Power Supply System
The PC216A and the PCCX32 operate on AC, DC power, or an optionally builtin battery pack, allowing the unit to be used as easily outdoors as indoors. When the AC and external DC power supplies are used jointly, the AC source is given priority, that is, the AC source is automatically selected for the operation. Should the AC power supply be interrupted, the unit instantaneously switches to the external DC power supply without any interruption in the operation. When the external DC power supply and the battery pack are used jointly, the external DC power supply powers the unit, with the battery pack acting as a back-up.
Power Save Mode
The playback circuit and the LCD backlight can be turned off during recording to reduce power consumption to a minimum.
Heavy Duty
The unit has been designed with an emphasis on durability, making it suitable for outdoor use.
RAW (Read After Write) Error Check
Equipped with a 4-head drum, the unit can play back data immediately after recording with the RAW function. During recording, errors are detected and indicated on the display panel.
Wide Dynamic Range
With a 16-bit linear-quantized pulse-code modulation (PCM) system, the PC216A offers a wide dynamic range of more than 80 dB. Since extra head room (2.5 dB) is provided above the reference level (±100%* or 0 dB) to capture signals within the given dynamic range, input signals which are in the vicinity of the reference level can be recorded without distortion, and the input level can be set easily.
All 16 bits of the PCM area are used for data. Announcements, amplifier setting information, and index information are stored in a separate sub code area.
* ±100% level, for example, is the level that corresponds to ±1 Vp input signal when the input range is set to "1V", or ±2 Vp input signal when the input range 1is set to "2V", and so on.
Reduction of Inter-channel Phase Difference
Multiplexing of data generated by simultaneous AD conversion of analog signals, together with careful handling of analog circuit, makes it possible to reduce the inter-channel phase difference to less than three degrees.
Automatic Calibration of DC Offset/Gain
When the power is turned ON, when the cassette is inserted, or in SLF CHK mode, the DC offset and the gain errors are automatically corrected by the builtin DSP (Digital Signal Processor). Any drift due to aging is eliminated, and high precision recording and playback can be performed without the need for adjustment.
Built-in Test Signal
The user can select various test signals; ±100% AC, ±100% DC or 0 V. These signals can be monitored at the data output connectors or recorded onto tape to be used as reference signals.
Highly Luminescent Display
The PC216A display panel incorporates a wide angle view LCD with a highly luminescent backlight, providing a high degree of readability. The bar meter can be displayed using either a percentage scale or a dB scale, as required.
Memory Search Function
Two search targets can be stored in the memory by marking location points on the tape using special keys for the simple search.
Fan Control Mode
This mode serves to stop the ventilation fan when the unit's internal temperature is low enough. This function makes the PC216A well-suited for applications such as acoustic measurement in an anechoic chamber when silence is required.
Highly Efficient Remote Control Unit (optional)
The remote control unit PCRM22 has a display almost identical to the main unit's display. Data input level, tape remaining and error check message are just a few of the functions provided. Furthermore, as the remote control interface conforms to the RS-232C standard, it is possible to use a host computer to control the main unit.

During playback, the MIC LED lights according to the voice annotation level (ANN/DATA switch is set to ANN) or signal level of the monitored channel (ANN/DATA switch is set to DATA).
Bar meter
The bar meter indicates the level for each channel.
• When the percentage scale is selected, the data signal level is displayed as a percentage (+100%, 0%, -100%, etc.) relative to the reference level (±100%).
The reference level (±100%) is defined as the level 33% below the full scale of the A/D or D/A converters. When the range setting is 1V, for example, the input level of ±1 Vp indicates ±100%.
In the case of DC signal or signals with slow amplitude change, a signal level (the peak level) of each channel is indicated by a single LCD segment. If signals with faster amplitude change are displayed, the level indications look like bars indicating positive and negative peak values. Therefore the percentage scale is useful to monitor the signals with DC offsets.
• When the dB scale is selected, the data signal level is displayed as a dB value (+2 dB, -6 dB, -20 dB, -∞ dB, etc.) relative to the reference level (0 dB).
The reference level (0 dB) is defined as the level 2.5dB below the full scale of the A/D or D/A converters. When the range setting is 1V, for example, the input level of ±1Vp indicates 0 dB.
The level is indicated in one direction regardless of the signal polarity. The percentage scale or the dB scale can be selected by using the dB/%
• The percentage scale of the dB scale can be selected by using the dB/% switch on the rear panel (Refer to 2-2 (2) ). The dB scale is suitable for acoustic measurements, while the percentage scale is suitable for measuring the data signals, which include a DC
component, i.e. stress, distortion, etc.
- The dots, 0% dots (for percentage display) or -∞ dB dots (for dB display), blink for monitored channels.
- The bar meters for valid channels only are displayed according to the mode selection.
O OVR
The OVR marks for each channel lights up when the signal level is at the over range. When the percentage scale is selected for the bar meter display, the OVR marks positive <+> or negative <-> side or both sides light up according to the signal level. The lighting mode can be selected between real-time and peak-holding. To select the mode, use the HLD/RAL switch on the rear panel (Refer to 2-2 (2 )).
🕑 ID
Any three digit number can be used as an ID number for discrimination, and it can written to any portion of the tape during recording. This ID number is shown on the ID display section.
In the SOURCE mode, the ID number displays the source index (values in the machine). In the TAPE mode, the ID number displays the tape index (Values recorded on the TAPE).
The auto-increment mode is set when A is displayed on the right side, and each time a recording operation is stopped the ID number increases by one.
SID/EVT
- The SID lights when START-ID is being recorded or played back. At each start of the recordings, START-ID is automatically recorded with 15-second duration (at normal speed).
- The EVT lights when EVENT-ID is being recorded or played back. EVENT-ID can be recorded via RS-232C commands. Refer to 12-2.
O CAUTION
Warning messages concerning low DC voltage, mechanical malfunction, condensation in the machine and data errors are displayed in this section. For details, refer to section 3-6.
MONI
Displays the channel number of monitored channel.
@ RANGE
Displays, for each channel, the values for the monitored channel input range either in the machine (SOURCE mode) or on the tape (TAPE mode).
| Display | 20 V | 10 V | 5 V | 2 V - | 1 V | 0.5 V |
|---|---|---|---|---|---|---|
| Input range | ±20 Vp | ±10 Vp | ±5 Vp | ±2 Vp | ±1 Vp | ±0.5 Vp |
±20 Vp, for example, is the range which becomes the reference level (±100% or 0 dB) when the +20 V peak or -20 V peak voltage is input.

3-6 Warning Display
If a malfunction occurs in the unit, the appropriate symbol will be shown by the warning display in the CAUTION area.
In this situation, perform the measures outlined below before operating the unit further.
(Low DC voltage)
This is displayed when either the battery voltage or the external DC voltage has dropped below the required level.
Replace the battery pack with a charged one, or check the DC power supply (11 to 30 V).
To prevent malfunction, and for longer operating times, replace the battery pack with a fully-charged one as soon as the low DC voltage symbol is displayed.
The durability of NP-1B (new and fully-charged) for continuous operation are as follows:
| NORMAL mode | P-SAVE mode | |
|---|---|---|
| PC216A | Approx. 40min | Approx. 60min |
| PCCX32 | Approx. 80min | Approx. 150min |
(Mechanical malfunction)
This is displayed when the drum or reel malfunctions, or if the cassette has not been loaded properly.
- 1. When a mechanical malfunction is detected, the tape will stop.
- 2. Eject and reload the cassette, then run the tape.
- 3. If the warning symbol is still displayed after step 2 has been performed, turn the power OFF, and then ON again.
- 4. If the malfunction is still present, contact a Sony service center.
(Condensation)
This is displayed when the moisture is condensed on the head drum caused by using the unit in an excessively cold or humid location, or moving from a cool to a warm location.
During this display, the tape will stop and the condensation will be removed by the internal heater.
Do not use the unit until the warning display has been extinguished.
Having a 4-head drum, the unit's read-after-write (RAW) system enables recording and playback to be performed (track recorded is immediately traced by two playback heads) simultaneously, and writing errors to be detected. If writing errors are detected by tracing the track, an error indication is shown on the display.
Causes of the writing error are either scratches or wrinkles on the tape, or head clogging (dirt build-up on the heads). Therefore, if writing errors occur, replace the cassette or clean the heads as appropriate using the supplied cleaning cassette. When the error check mark is randomly displayed, the analog data can be reproduced by the interpolation function of the unit.
This error message will also be displayed when an unrecorded portion of the tape is played back. If the error mark is persistently displayed beyond that section of tape, replace the tape or perform head cleaning.
If the error mark is still displayed, contact a Sony service center.
3-7 Notes on Key Operations and Operation Modes
Calibration
The DC offset and gain errors are automatically calibrated at POWER ON and in the self-check mode. When a self-check is conducted without a cassette inserted, only calibration is performed.

START ID Search
During the first 15 seconds of recording, a START ID is automatically recorded on the tape to allow the position of the start of recording to be accessed swiftly. Press the SEARCH key, then either the FF key or the REW key to start forward START ID searching or reverse START ID searching respectively.
Press the STOP key to exit the search mode.
Manual Search
Manual Search is used to search for the target point using the displayed index (i.e. address, time, etc.) in the forward and reverse directions on the tape. The forward manual search mode is set by pressing the FF key during playback. The reverse manual search mode is set by pressing the REW key. The manual searches are conducted at 16× normal tape speed.
The PC216A can perform the recording and playback of the analog data signal up to 32 channels at one time, using the optional channel expansion unit PCCX32.
5-1 Precautions
- Connect the PCCX32 to the PC216A when its power is turned OFF.
- The PCCX32 operates with independent power supply from the PC216A. Supply the specified power (external AC/external DC/built-in battery) to the PCCX32.
- When the power voltage of the unit becomes under the specified level, the POWER LED of the unit will blink to alert.
- A ventilation fan is attached to rear side of the unit. So, be careful not to block it.
5-2 Names and Functions of Each Part
Front Panel
O POWER LED
Lights when power is supplied to the unit, and blinks when the power voltage lowers the specified level.
Turn the power ON/OFF with the POWER switch on the PC216A rear panel.
Ø Bar meters
Displays the analog data signal level of channels 17 to 32. Using the dip switches on the PC216A rear panel, either percentage display or dB display is selected. Set the switch to lower position to display in percentage scale (10 %, 50 %, 100 %, 125 %) in the left, and set to upper position to display in dB scale (-20 dB, -6 dB, 0 dB, +2 dB) in the right. In either case, the uppermost LED will light up when the level is beyond the range of each channel.
Since the bar meter of the PCCX32 indicates the level in one direction regardless of the signal polarity, even when the level is displayed in percentage scale, the indication may differs from that of the PC216A. The analog data signal level for channels 17 to 32 can also be displayed on the PC216A. Refer to 2-1 (2) .
O INPUT connectors
Used to input the analog data signals of channels 17 to 32.
32ch LED
Lights during the 32-channel mode.

Side Panel
OUTPUT connectors
Used to output the analog data signals of channels 17 to 32.
Output level adjustment potentiometers
Used to increase and decrease the output level for each channel (17 to 32). Refer to 2-3 (2 ).
5-3 Connecting to the PC216A
- 1 Make a connection between the EXPANSION connectors of PC216A and PCCX32, using the supplied cable.
- 2 Turn ON the power of the PC216A.
3 Using the supplied combining frames (totally 4 for the front and back, right and left), attach the PCCX32 to the PC216A, so that will make it easy to carry and fix onto a base rack. Refer to the following for attachment.
Attaching the Combining Frames
- 1 Prepare a 3 mm Phillips screwdriver.
- 2 Turn over the PC216A. Using the screwdriver, remove the six screws ⊕PS3 × 8 (with spring washers) fastening the front and back feet. Remove the feet from the PC216A.
- 3 Remove the four small binding screws ⊕B3 × 6 (black) at the right and left sides of the PC216A.
- 4 Remove the four small binding screws ⊕B3 × 6 (black) at the right and left sides of the PCCX32.
5 Mount the PC216A onto the PCCX32. With the guard sheet sides facing inside, temporarily fix the combining frames with the supplied four small binding screws ⊕B3 × 12 (black). The four combining frames are all same type.
Fix all four combining frames temporarily in the same way.
6 After temporarily fixing the four frames, fix them securely.
Connecting Data Signals
Using an optional BNC cable, connect the INPUT connector of each channel to a signal source. The data signals of channels 17 to 32 can be monitored with the MONI connector of PC216A.
Recording (Analog Mode)
Use the SPEED key and the CH/NEXT key of the PC216A to set the 32-channel mode.
Note
When the 32-channel mode cannot be selected, reconfirm the connection. Refer to section 4-2, since the data-recording procedure is the same as using the PC216A alone.
Playback (Analog Mode)
The PCCX32 is only active for the 32-channel mode playback. Refer to section 4-3, since the data playback procedure is the same as using the PC216A alone.
When a tape which has been recorded in the 32-channel mode is played back using the PC216A without PCCX32, the analog data of 17 to 32 channels cannot be output while the analog data of 1 to 16 channels and the parallel digital data can. And in this case, which channel mode (16-channel or 32-channel) was selected at the recording can be recognized by the following method: 32-channel mode: The channel number between 17 to 32 can be selected and
indicated at the MONI area on the display.
16-channel mode: The above channel number can not be selected and indicated.
With two PC216As in synchronizing mode, the number of channels can be doubled without changing the frequency band. As the slave machine is locked to the master's clock, word-accurate synchronous recording is possible. The recording and playback can also be performed in different channel modes or analog/digital modes according to the setting of the master and slave machines.
6-1 Precautions
- The power of both machines must be turned OFF when connecting the both machines with the SYNC cable (PCCK21).
- The power is supplied separately. Supply the specified power (external AC/ external DC/built-in battery) to both machines.
- First turn ON the power of the master machine, and then the slave machine.
- If both machines are set to the same mode, i.e. master or slave, they can not enter into the synchronizing mode and will be operated independently.
- When the master machine is automatically stopped by EOT, the slave machine will be stopped at the same time. On the other hand, the master machine will keep running even when the slave machine is stopped by EOT due to the difference in tape length.
- •Without the connection for the synchronizing mode, the each machine operates as a master regardless of the positions of the DIP switches on the rear panel.
- 1 Make a connection between the EXT. CONTROL connectors of PC216As, using the optional SYNC cable PCCK21 when the power of both machines are turned OFF.
- 2 Using the SLV/MST switch on the rear panel, set one machine as a master and the other as a salve. Set the switch to lower position to use the machine as master, and set to upper position to use as slave. See page 2-19.
- 3 First turn ON the power of the master machine, and then the slave machine.
- 4 Make sure that the SYN LED on the front panel of the master machine starts blinking and the SYN LED of the slave machine does not light or blink.
6-3 Operations
1. SPEED (Tape speed)
The SPEED setting on the slave machine follows the setting on the master machine.
2. Tape transport control
The modes on the slave machine follow ones on the master machine, such as REC, PLAYBACK, FF, REW, E-E, PAUSE and manual search. They are also linked when the machine is externally controlled from the REMOTE connector.
Note
The slave machine can not control the operation of the master unit.
3. Counter/Address
The tape counters (COUNT) of both machines are automatically reset to zero at the each start of recording. The COUNT of the slave machine follows that of the master machine during recording. Thus the data recorded on the master and the slave tapes at the same ADDRESS are exactly synchronized.
4. ID number
The ID number can be preset for the master and the slave machines independently.
The ID increment of both machines can be performed simultaneously by pressing ID key of the master machine.
If the master machine is set to auto ID increment mode (refer to the page 4-3), the ID numbers of the both machine are auto-incremented at each stop of recording.
Except above-mentioned settings, the master and slave machines can be set individually, such as analog/digital mode, B/C mode, Input range, etc.
Note 1: Synchronous playback
Although the master and the slave machines run synchronously in FWD mode, the slave machine does not automatically chase the master machine for the same ADDRESS.
However, the data at the same ADDRESS for the both tapes are the data captured at the same sampling time. So "off-line synchronization" is possible by transferring the data from the specific ADDRESS on both the master tape and the slave tape to a host computer.
Note 2: SYN LED
In the setting for synchronous mode, the indication of the SYN LED varies according to the status of the machines.
| Status | MASTER | SLAVE |
|---|---|---|
| Recording in sync condition | ON | OFF |
| All other status other than above | BLINK | OFF |
| Erroneous operation* | OFF | OFF |
* Check setting and cabling.
Note 3: Abnormal conditions
The error code on the LCD display and SYN LED indication will appear if abnormal conditions happen during synchronizing operation.
| MAS | TER | SLAVE | |||
|---|---|---|---|---|---|
| Error code | SYN LED | Error code | SYN LED | ||
| Power down at Master | BLINK | ||||
| Power down at Slave | E05 | BLINK | |||
| Failure in the connection* | E05 | BLINK | E05 | BLINK | |
* When both machines are restarted by Power-on, each machine will run as a master independently.

12-2 Command Contents
Communication between the computer and PC216A is performed by transmitting commands from the computer and returning status from the unit in response to the commands. Each unit of both transmission and reply is called a "record". The terminator characters which indicate the end of the records are "CR" (carriage return) and "LF" (line feed).
(The unit acknowledges CR as the record terminator even if LF is missing.) Before setting the commands, check that the unit is in the "receiving possible" condition with the "RDY?" command. The unit returns the "RDY" command when it is ready for receiving. When transmitting the status command, confirmation using with the "RDY?" command is not necessary. All communications are performed using ASCII codes.
The symbols on the command/status display are as follows:
indicates space (blank). (1), (2), (3)... are characters in the command, and indicate 0 to 9 or the ASCII characters of the alphabets. [] indicates PCCX32 only. RSVD indicates reserved.

The PC216A is a data recorder capable of analog data input/output but data is stored on the magnetic tape as a digital (binary) formatted code. The digital formatted code can be output during playback in addition to analog data. This makes data transfer possible (either directly or via the digital data interface unit PCIF11A/PCIF-1) for high-accuracy data analysis.
An LSB channel is provided in addition to the main analog data channels (2, 4, 8, 16, and 32 channels), facilitating the recording/playing back of digital data simultaneously with main-channel analog data.
Also, when the digital mode is selected and the serial digital input/output function (conformed to RS-422A) is available, the PC216A can also be used as a digital data recorder.
13-1 Function
Parallel Data Output (analog mode)
The playback of the analog main data signal (2, 4, 8, 16, or 32 channel) can be output in a 16-bit parallel format (main data 15-bit + LSB 1-bit). Data coding is offset binary*.
Data transfer rate is 96 k words/s (normal speed), or 192 k words/s (double speed). Interface output level is TTL.
LSB Channel Input/Output (analog mode)
Use of the least significant bit (LSB) of quantized 16 bits for digital I/O, the LSB channel can be used to record/play back digital signals (i.e. engine rotation pulse, control signal, time code signal, etc.) independently from the main channel analog signals (2, 4, 8, 16, or 32 channel). Although the dynamic range of 80 dB and other analog characteristics are secured as quoted. Both input and output levels are TTL compatible. Sampling frequency is 96 kHz (normal speed) or 192 kHz (double speed).
Serial Input/Output (digital mode)
The serial digital data can be input and output between the PC216A and an external PCM encoder/decoder. The transfer rate is 1.536 Mbps (normal speed) or 3.072 Mbps (double speed) when synchronized, and less than 0.768 Mbps (normal speed) or less than 1.536 Mbps (double speed) when unsynchronized. The input/output level conforms with RS-422A.
* Offset binary
Offset binary is a variation of the 2's complement system, in which the MSB is inverted. In the PC series, 0% data is assigned to 8000H. For more details, see item "DATA" on page 13-5.

13-6 LSB Channel
Input/output digital signals to the specified pins of the DIGITAL DATA I/O connector (see page 13-2). When the data recorder is in record mode, LSB input signal through the DIGITAL DATA I/O connector is recorded at the same time as the main data signals. When the unit is in playback mode, the LSB signal is output through the DIGITAL DATA I/O connector.
Note
Care should be exercised in the selection of the sampling rate, in order to avoid the distortion inherent in discrete sampling.
Fig. 13-6-1. AN EXAMPLE OF PHASE SHIFT CAUSED BY SAMPLING
13-7 Serial Digital Input/Output
By setting the PC216A into Digital Mode, it is possible to record an incoming serial digital signal generated by an external PCM machine (such as a digital telemetry system) where analog signals, typically generated from multiple transducers, are A/D-converted and formatted (encoded and multiplexed). The serial input and output terminals are provided in the DIGITAL DATA I/O connector.
In the Digital Mode the PC216A functions as a transparent storage device, i.e. the played back digital signal is equivalent to the incoming signal to the recorder. Thus, the Digital Mode is well suited to record a digital bit stream which is pre-formatted/ encoded by external PCM equipment.
There are two types of data transfer between the PC216A and external PCM equipment: synchronous mode and asynchronous mode.
Synchronous Mode
In this mode, the incoming digital signal generated by the external PCM equipment must be synchronized by the PC216A and the bit rate must match the bit clock SCLK. The SCLK is provided in the DIGITAL DATA I/O connector to lock the external PCM equipment (PC216A can not be synchronized by an external clock). The incoming digital signal (NRZ) is in sync with the rising edge of the SCLK, and the playback digital signal is generated by clocking the data within the recorder as illustrated in Fig. 13-7-1. In synchronous mode, it is possible to record and play back a digital signal at the maximum bit rate, i.e. 1.536 Mbits/ sec. at the normal speed mode or 3.072 Mbits/sec. at the double speed mode.
Fig. 13-7-1. AN EXAMPLE OF SYNCHRONOUS MODE (NRZ SYSTEM)
Asynchronous Mode
In asynchronous mode the bit rate of the external PCM equipment is independent of the clock frequency (SCLK) of the PC216A. In this mode, the data transfer is made without using SCLK. The incoming digital signal (NRZ) is sampled using the SCLK and then recorded. Because of asynchronous sample timing, the length of the sampled data bits of the incoming data will vary. The data can not be correctly reproduced if the amount of fluctuation exceeds one half of the original bit length. In other words, the maximum bit rate must be less than half of the sampling rate, i.e. 0.768 Mbits/sec at the normal speed or 1.536 Mbits/sec at the double speed. Figure 13-7-2 shows an example of timing when the incoming bit rate is more than half of the sampling rate, and Fig. 13-7-3 shows the case when the incoming bit rate is less than half of the sampling rate.
Fig. 13-7-2. AN EXAMPLE OF ASYNCHRONOUS MODE (INPUT BIT RATE IS NOT BELOW HALF OF THE SAMPLING RATE, NRZ SYSTEM)
