LV2285VB
Continued from preceding page.
Pin No.
Pin name
18 SDA
DC voltage (V)
I²C data input.
Function
19 I2CSW
20 TC
The change switch of the I²C data input pin.
When Pin 19 = GND case, Audio control I/F is
selected (Pin 2/23). In one side, when Pin 19 =
VCC case, I²C I/F is selected (Pin 17/18).
2.8
Connect capacitance. Turn-off time is in
proportion to this capacity value.
21 76k OSC OUT
2.0
For stereo modulator pilot signal and sub
carrier. 76kHz crystal should be connected
between Pin 21 and Pin 22.
