Function

26

Sync out

This pin is for output a

self-diagnostic sync signal. The

signal separated from VinTV VinV1,

VinV2, Y/VinS1, Vout1, Vout2, Yout,

or Cout is outputted from this pin. In

addition, the signal derived from

Lout1, Rout1, Lout2, or Rout2 is also 26

output from this pin for use in audio

block diagnosis.

This is an open-collector output.

Make sure that the current flowing

into this pin is 2.0 mA or less.

VinV2

This pin is for input a composite

video signal from an external source

(V2 channel). This pin can also be

used for PIP signal input. The signal

fed into this pin is presented to

Vout1, Vout2, Yout, and Cout. The

same signal is also output from Det

Select as a sync separation signal.

The input dynamic range of this pin

is 2.0 Vp-p and the input resistance is

30 kΩ.

LinV2

This pin is for input a left audio

signal from an external source (V2

channel). This pin can also be used

for PIP signal input. The signal fed

into this pin is presented to Lout1

and Lout2.
