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/chrome 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

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.

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 k

 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 voltage or falling voltage at V

CC

ON/OFF.

For this countermeasure, connect 10 k

 to 20 k

 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

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.

MPX ON/OFF Switch

MPX-OFF mode means that signal from input amp doesn’t go through the MPX filter, but signal goes

through the NR circuit after being attenuated 3 dB by internal resistor.  Refer to figure 5.  For not cause any

level difference between MPX-ON mode and MPX-OFF mode, it is requested to use MPX-filter which has

definitely 3 dB attenuated.  And when applying other usage except figure 5,

take consideration to give bias voltage to NR-IN terminal by resistor or so on because internal of NR-IN

terminal has no bias resistor.

Application as for the Dubbing Cassette Deck

HA12167FB/HA12169FB series has unprocessor signal from recording out terminals during playback

mode.  So, it is simply applied for dubbing cassette decks.

Injector Current

HA12167FB/HA12169FB has logic circuit which is fabricated by I

2

L into IC.  To operate this circuit, it is

required enough injector current.  Injector current goes into from the INJ pin (pin 38) and external resistor

is required to connect to this pin for adequate current.  The value of external resistor is obtained by using

following equations.  And put them with ±10% tolerance value which is calculated.  V

INJ

 can allow to

connect to V

CC

 shown below.  Large injector current fear to cause mis-operation of Logic under the

condition of high temperature.  Also, small injector current fear to cause mis-operation (stop operation).

Under the condition of low temperature.  Therefore, pay attention to have good stability of V

Gain Control of Electronic Volume

HA12167FB/HA12169FB is designed in order to change the gain by DAC fabricated into IC.  To reduce

the click noise when changing volume gain instantaneously, required to connect the capacitor and resistor

(CR time constant) to CONT pin (pin 13, 48, 68, 73).  These terminals are also be used as output pin of

DAC.  Therefore, by forcing voltage and current to these terminals, it is applicable to control volume gain

directly.  But, voltage forced to these terminals must be from V

CC

/2 –2 V to V

CC

/2 (for split supply use, –2 V

to 0 V) in this case.  And, this case, change of a gain depending on a temperature gets large.

Figure 14   Equalizer Peak Gain vs. DAC Step Characteristics (2)

When the (variable) width of the DAC step is to be changed, the gain at step 0 or at step 63 must be

changed.  The step 0 gain can be changed using R’

GP

 as shown in figure 13. Also, R’

GP

 can be switched

using the tape selector, as shown in figure 15.  However, it is necessary to take into account that the value

of R

ADJ

, which sets the step 63 gain, is also used for the output bias.  When the load resistance on pin 33 is

R

L

, the following formula gives the output bias, V

BMAX

.

V

BMAX

 = 2.4 

×

 R

L

 / R

ADJ

Therefore, it is possible to compensate the output bias, V

BMAX

 for the R

ADJ

 setting by changing R

L

.

Note:

R

ADJ

 should be in the range 16 k

 to 75 k

.
