PIN DESCRIPTION
V
CC
Positive Power Supply (Pin 15)
This pin is normally tied to the + 5.0 V . A 0.1 µF decoupling
capacitor should be used.
GND Ground Pin (Pin 5)
This pin is normally tied to 0 V.
GNDA Analog Ground (Pin 3)
Analog ground is internally biased to (VCC – VSS) / 2. It should be tied to ground through a 0.1 µF and 1 00 µF capacitor.
X1 Crystal Oscillator Output (Pin 7)
Connecting a 3.579545 MHz ± 0.1% crystal between X1 and X2 will cause the transmit frequencies to be within ± 64 MHz of nominal. X1 is capable of driving several CMOS gates. An external clock may be applied to X2. X1 should then be left open.
X2 Crystal Oscillator Input (Pin 8)
Refer to X1.
SCK Shift Resister Clock Input (Pin 13)
This pin is the clock input for the 15–bit shift register. Serial data is loaded into the shift register on the rising edge of this clock.
DATA Serial Data Input (Pin 12)
This pin is the 15–bit serial data input. This data deter­mines the mode, DTMF signal, transmit attenuation, carrier detect time, channel, and transmit squelch.
ENB Enable Input (Pin 14)
Data is loaded into the 15–bit shift register when this pin is at a logic low. When this pin transitions from a logic high to low, the data is transferred to the internal latch on the falling edge of ENB. New data loaded into the shift register will not affect the device operation until this pin transitions from high to low. (See Figure 2.)
TxD Transmit Data Input (Pin 11)
This pin is the transmit data input, The mark frequency is generated when this pin is at the logic high level. The space frequency is generated when the pin is at a logic low.
RxD Receive Data Output (Pin 10)
This pin is the receive data output. A high logic level of this pin indicates that the mark carrier frequency has been re­ceived, and a low logic level indicates the space carrier fre­quency has been received.
SD Carrier/Call Progress Tone Detect (Pin 9)
This pin is the output from the carrier detector or call prog­ress tone detector. This pin works as a carrier detector in the FSK mode and as the call progress tone detector in the CPTD mode. The output goes to a logic low level when the input signal reaches the minimum threshold of the detect level that is adjusted by the CDA voltage. When SD
= H, the receive data output (RxD) is clamped high to avoid errors that may occur with loop noise. The SD
pin is also clamped high in the other modes except during the power–down mode.
TxA1 Non–Inverting Transmit Analog Carrier Output (Pin 18)
This pin is the line driver non–inverting output of the FSK and tone transmit analog signals. A + 6 dBm (max) differen ­tial output voltage can be obtained by connecting a 1.2 k load resistor between Tx1 and Tx2. Attention must be set so as not to exceed this level when an external input is added to the DSI pin. A telephone line (600 ) is driven through an external 600 resistor. In this case, the output level be­comes about half of differential output.
Page 6
MC145444 MOTOROLA 6
TxA2 Inverting Transmit Analog Carrier Output (Pin 17)
This pin is the line driver inverting output. The signal is equal in magnitude, but 180° out of phase with the TxA1 (refer to TxA1).
RxA Receive Signal Input (Pin 19)
This pin is the receive signal input. The pin has an input impedance of 50 k (min).
RxGC Receive Gain Adjust (Pin 20)
This pin is used to adjust the receive buffer gain. To adjust the gain, the signal from the RxBO through a divider is added as a feedback. This pin may be held open when the gain adjustment is not needed.
RxBO Receiver Buffer Output (Pin 1)
This pin is the receive buffer output.
DSI Driver Summing Input (Pin 16)
This pin is the inverting input of the line driver. An external signal is transmitted through an external series resistor R
DSI
.
The differential gain G
DSI
= (V
TXA1

)/V
DSI
is deter-
mined by the following equation.
G
DSI
= – 2Rf / R
DSI
, Rf 20 k
DSI should be left open when not used.
CDA Carrier Detect Level/CPTD Level Control (Pin 4)
The carrier/call progress tone detect level is programmed with a CDA pin voltage.
When this pin is held open, the CDA voltage is set to
1.2 V with an internal divider. The detect level is set at – 44 dBm (typ) for off to on, and – 47 dBm (typ) for on to off. The minimum hysteresis is 2 dB. This pin has a very high input impedance so it should be connected to GND with a
0.1 µF capacitor to keep it well regulated. An external voltage may be applied to this pin to adjust the carrier detect threshold. The following equations may be used to find the CDA voltage required for a given threshold voltage.

FTLC Filter Test (Pin 2)
This pin is a high–impedance filter output. It may be used to check the receive filter. This pin also may be used as a demodulator input. In normal operation, this pin is connected to the GNDA through a 0.1 µF bypass capacitor. This pin handles very small signals so care must be used with the capacitor’s wiring.
TLA Transmit Carrier Level Adjust (Pin 6)
This pin is used to adjust the transmit carrier level that is determined by the value of the resistor (RTLA) connected
between this pin and GND. The maximum transmit level is obtained when this pin is connected to GND (RTLA = 0).

data.

Figure 3 presents the 15–bit serial data timing, starting with the carrier detect time, CD1, followed by the channel, the tone frequency, the transmit squelch, the transmit attenu­ator, and the function mode. This data is loaded into the inter­nal shift register at the rising edge of the SCK signal and latched at the falling edge of the ENB signal.
FUNCTION MODE
Modes are selected from the following 3–bit data (M2 – M0, see Table 1).
Table 1. Function Mode Truth Table
M2 M1 M0 Function Mode

The following paragraphs describe each function. Table 2 presents each output status.
FSK Mode
The transmitter and the receiver work as a FSK modula­tor/demodulator. The SD
pin output is the carrier’s detect
signal.
Analog Loopback Mode
TxA1 connects to the receiver internally and FSK signals are demodulated. The frequency of the receiver is set up with the same frequency as the transmitter. The SD
pin output is the carrier detect signal. An IC self test is supported with this function.
CPTD Mode
The receiver detects a 400 Hz call progress tone. The
detect signal comes from the SD
pin. The transmitter is
disabled.

The transmitter works as a DTMF tone generator. The

Single Tone Mode
The transmitter output is one of the DTMF eight frequen-
cies. The receiver is disabled.
Power–Down Mode 1
Internal circuits except the oscillator are disabled, and all outputs except the X1 pin go to the high impedance state. The supply current decreases to 300 µA (max).
Power–Down Mode 2
All circuits including the oscillator stop working and all out­puts go to the high impedance state. The supply current de­creases to 1.0 µA (max).
Transmit Attenuator
Four–bit serial data (A3 – A0) sets up the analog transmit level in the FSK, answer tone, DTMF, analog loopback, and single tone mode. The range of the transmit attenuator is 0 – 15 dB in 1 dB steps. The external signal (DSI) is not affected by this attenuator.
TONE FREQUENCY
The DTMF tones or the single tone mode is selected by the 4–bit serial data (T3 – T0).
