HA12209F

Audio Signal Processor for Cassette Deck (Dolby B-type NR with Recording System)

ADE-207-221A (Z)

2nd Edition Jun. 1999

Description

HA12209F is silicon monolithic bipolar IC providing Dolby noise reduction system*, music sensor system, REC equalizer system and each electronic control switch in one chip.

Functions

Dolby B-NR

×

2 channel

REC equalizer

×

2 channel

Music sensor

×

1 channel

Each electronic control switch to change REC equalizer, bias, etc.

Features

REC equalizer is very small number of external parts and have 4 types of frequency characteristics built-in.

2 types of input for PB, 1 type of input for REC.

70µ -PB equalizer changing system built-in.

Dolby NR with dubbing double cassette decks.

Unprocessed signal output available from recording out terminals during PB mode.

Provide stable music sensor system, available to design music sensing time and level.

Controllable from direct micro-computer output.

Bias oscillator control switch built-in.

NR ON/OFF and REC/PB fully electronic control switching built-in.

Normal-speed/high-speed, TYPE I/TYPE II and PB equalizer fully electronic control switching built-in.

Available to reduce substrate-area because of high integration and small external parts.

Note: Depending on the employed REC/PB head and test tape characteristics, there is a rare case that the REC-EQ characteristics of this LSI can not be matched to the required characteristics because of built-in resistors which determined the REC-EQ parameters in this case, please inquire the responsible agent because the adjustment of built-in resistor is necessary.

Power Supply Range

HA12209F is designed to operate on single supply.

Power Supply Range

 

 

Single Supply

10V to 15V

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

The minimum value of the overload margin is specified as 12dB by Dolby Laboratories.

Reference Voltage

For this IC, the reference voltage (VCC/2) occurrence device is built-in as AC grand. A capacitor for a ripple filter is greatly small characteristic with 1/100 compared with conventional device.

And, the reference voltage are provided for the left channel and the right channel separately.

Like the figure 6(2), Recovery time is variably possible by value of resistor R12. But Attack time gets about fixed value. Attack time has dependence by input level. When a large signal is inputted, Attack time is short tendency.

Note: 2.

Music Sensor Output (MSOUT)

As for internal circuit of music sensor block, music sensor out pin is connected to the collector of NPN type directly, output level will be “high” when sensing no signal. And output level will be “low” when sensing signal.

Connection with microcomputer, it is requested to use external pull up resistor (RL = 10k to 22k)

Note: Supply voltage of MSOUT pin must be less than VCC voltage.

The Tolerances of External Components

For Dolby NR precision securing, please use external components shown at figure 7.

If leak-current are a few electrolytic-capacitor, it can be applicable to C2 and C15.

External resistor R8, R10 which corresponded with tape positions and bias out voltage are relater with below.

Vbias =

(R10 or R8) + R9

 

 

Bias switch follows to a logic of 14 pin (B 120/70).

Note: A current that flows at bias out pin, please use it less than 5mA.
