Notes: 1.

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.

A standard level of MS input pin 25.9 mVrms, therefore, the sensitivity of music sensor (S) can request it , by lower formulas.

A = MS Amp Gain

B = PB input Gain × (1/2)*1 C = Sensed voltage

20log (A × B) = D [dB] C = 130 [mVrms]

	S = 14	D [dB]

Notes: 1. Case of one-sided channel input

•Time constant of detection

Figure 6(1) generally shows that detection time is in proportion to value of capacitor C16. But, with Attack *2 and Recovery *3 the detection time differs exceptionally.

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.
