HA12167FB/HA12169FB

Audio Signal Processor for Cassette Deck (Deck 1 Chip)

ADE-207-110B (Z)

3rd. Edition

June 1997

Description

HA12167FB/HA12169FB is silicon monolithic bipolar IC providing REC volume system, Level meter system and Dolby noise reduction system in one chip.

Functions

• REC equalizer × 2 channel

• Equalizer volume × 2 channel

• Dolby B/C NR × 2 channel

• REC/PB input electronic volume × 2 channel

• Level Meter × 2 channel

• DAC for adjusting bias × 2 channel

Features

• Available to create characteristics of REC equalizer by changing external resistor, no coil

• Equalizer volume is available to calibrate recording automatically with micro-controller

• Electronic volume built-in is available to set the level of recording and play back automatically with

micro-controller

• 4 types of input (3 out of 4 are by way of electronic volume)

• Input electronic control switching is irrelevant to REC/PB electronic control switching

• Dolby noise reduction system is available with double cassette decks (Unprocessed signal output

available from recording out terminals during PB mode)

• Log-compressed level meter output is range from 0 V to 5 V (Usable as music search switchable gain of

0 dB and 20 dB respectively)

• Normal-speed/high-speed, normal/metal/ch rom e fully electronic control switching built-in

• NR-ON/OFF, Dolby B/C, MPX ON/OFF fully electronic control switching built-in

• Reduction of the number of pins by transfered serial data to electronic volume control switching and

another control switching (Controllable from micro-controller directly)

• Small the number of external parts

HA12167FB/HA12169FB

Application Note

Power Supply Range

HA12167FB/HA12169FB are designed to operate on either single supply or split supply.

The operating range of the supply voltage is shown in table 1.

Table 1 Supply Voltage

Type No. Single Supply Split Supply

HA12167FB 12 V to 15 V ±6.0 V to 7.5 V HA12169FB 11 V to 15 V ±6.0 V to 7.5 V

The lower limit of supply voltage depends on the line output reference level.

The minimum value of the overload margin is specified as 12 dB by Dolby Laboratories. HA12167 series are provided with two line output level, which will permit an optimum overload margin for power supply conditions.

Reference Voltage

For the single supply operation these devices provide the reference voltage of half the supply voltage that is the signal grounds. As the peculiarity of these devices, the capacitor for the ripple filter is very small about 1/100 compared with their usual value. The Reference voltage are provided for the left channel and the right channel separately. The block diagram is shown as figure 1.

Operating Mode Control

HA12167FB/HA12169FB provides fully electronic switching circuits. All switches are controlled by serial data.

Table 2 Threshold Voltage (VTH)

Pin No. Lo Hi Unit

42 –0.2 to 1.5 3.5 to 5.3 V 39, 40, 41 –0.2 to 1.0 4.0 to 5.3 V Notes: 1. Voltages shown above are determined by internal circuits of LSI when take pin 47 (DGND pin) as

reference pin. On split supply use, same VTH can be offered by connecting DGND pin to GND pin.

This means that it can be controlled directly by micro processor.

2. Each pins are on pulled down with 100 kΩ internal resistor . Therefore, it will be low-level when each pins are open.

3. Note on serial data inputting (a) The clock frequency on CLK must be less than 500 kHz. (b) Over shoot level and under shoot level of input signal must be the value shown below.

When connecting microcomputer or Logic-IC with HA12167FB/HA12169FB directly, there is apprehension of rash-current under some transition timming of raising voltag e or falling voltage at V ON/OFF.

CC

For this countermeasure, connect 10 kΩ to 20 kΩ resistor with each pins. It is shown in test circuit on this data sheet.

In case of changing NR-ON/OFF at the C-mode, for the countermeasure of the noise of pop, perform the following processes.

In case of changing NR-OFF to NR-ON at C-mode. C-mode, NR-OFF → B-mode, NR-OFF → B-mode, NR-ON → C-mode, NR-ON.

In case of changing NR-ON to NR-OFF at C-mode. C-mode, NR-ON → B-mode, NR-ON → B-mode, NR-OFF → C-mode, NR-OFF.

Serial Data Formatting

14 bit shift register is employed.

CLK and data are stored during STB being high and data is latched when STB goes high to low.

Reset goes reset a state when reset low and high releasles reset. (High fixed at use time)

Attention Point of Serial Interface

• Reset goes low condition when a power supply is ON or OFF.

• Characteristics select of Bias DAC is connected with equalizer tape selector.

• Bias DAC register is all low when a time of tape select.

• Bias DAC register is all low and Bias DAC out is dropped low level at compulsion by force.

• Input pin select, REC/PB select and Input volume gain select does not select at the same time.

• Input volume must go mute condition when selected of RPI is input pin select.
