HA12203NT/HA12204NT

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

ADE-207-222B

Target Specification

3rd Edition

Jun. 1999

Description

HA12203NT is silicon monolithic bipolar IC providing Dolby noise reduction system*1, music sensor system, REC equalizer system and each electronic control switch in one chip.

Note: 1. Dolby is a trademark of Dolby Laboratories Licensing Corporation. A license from Dolby Laboratories Licensing Corporation is required for the use of this IC.

Functions

Music sensor

×

1 channel

Pass amp.

×

2 channel

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

Note: 2. HA12204NT is not built-in Dolby noise reduction system.

Features

REC equalizer is very small number of external parts and have 6 types of frequency characteristics built-in.*3

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, Normal / Crom / Metal*3 and PB equalizer fully electronic control switching built-in.

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

HA12203NT/HA12204NT

Note: 3. HA12204NT have 4 types of frequency characteristics.

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 built-in resistor is necessary.

Each pins are on pulled down with 100 kΩ internal resistor.

 

 

 

 

 

 

 

 

 

 

 

 

Therefore, it will be low-level when each pins are open.

 

 

 

 

 

 

 

 

 

 

 

 

But 19 pin are mid-level when it is open.

 

 

 

 

 

 

 

 

 

 

 

 

2.Over shoot level and under shoot level of input signal must be the standardized (High: VCC, Low: –0.2V).

3.For reduction of pop noise, connect 1µ F to 22µ F capacitor with mode control pins.

But it is impossible to reduce completely in regard to Line mute, therefore, use external mute at the same time.

Like the figure 6(2), Recovery time is variably possible by value of resister R18. 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.

Notes 2. Attack

: Nonmusic to Music

3. Recovery : Music to Non-music

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 = 10 k• to 22 k•) 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 C5 and C23.

Note: As Dolby-NR aren't built-in at HA12204NT, R3, C5 and C23 aren't necessary.

REC Equalizer

The outlines of REC Equalizing frequency characteristics are shown by figure 10. Those peak level can be set up by supplying voltage. (0 V to 5 V, GND = 0 V) to 30pin (GPCAL).

And whole band gain can be set up by supplying voltage (0 V to 5 V, GND = 0 V) to 31pin (RECCAL).

Both setting up range are ± 4.5dB. In case that you don't need setting up, 30 pin, 31pin should be open bias.

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 care, please inquire the responsible agent because of the adjustment of built-in resistor is necessary.

Since an output pin and an input pin for REC-EQ are adjacent, it will easily oscillate if patterns run abreast.
