Data Transmission of Fixed Equalizer Setting

• Faulty operation in the communication error occurrence.

Fixed equalizer setting premise no-change setting after setting is done once.

By this premise, A noise countermeasure circuit of the setting change isn’t built in.

Therefore, It has the possibility that noise is made by communication error.

These countermeasures are taken by this IC as it is shown in next page.

 Fixed equalizer setting change in the communication error occurrence.(example)

LATCH condition

D10 D11 D12 D13 D14 D15

[ Transmitting data of normal.]

DATA

CLOCK

LATCH condition

D10 D11 D12 D13 D14 D15

[ Transmitting data of communication error. ]

DATA

CLOCK

D4 is lack.

Communication error occurrence.

SLOT 1, f0 setting: 300Hz, Q setting:3.0, Gv setting: -8.0dB

SLOT 1, f0 setting: 300Hz, Q setting: 3.0, Gv setting: 0dB

* In the case of the upper figure, Fixed equalizer gain setting of FRONT Lch low range

occur faulty operation, and it has the possibility that noiseis made.

Gv= -8.0dB

⇒ Gv= 0dB
