Description

15k

Sync signal input for V sync separation.

147

46

Input a 2Vp-p Y signal (or a 0.6Vp-p

4.1V sync signal).

20µA

47 HSIN

48 SYNCOUT

49 VM

50 SCL

14k

Sync signal input for H sync separation.

147

Input a 2Vp-p Y signal (or a 0.6Vp-p sync

47

3.2V signal).

10µA

Sync signal output for VSIN and HSIN.

1.2k

The output can be selected from the

internal sync signals (Pin 53 or Pin 55) or

147

48

the external sync signal (Pin 56) by the

40k

I2C bus.

Output signal level: 2Vp-p

240µA

(0.6Vp-p sync only)

Input/output gain: 6dB

Outputs the differential waveform of the

VM (Velocity Modulation) Y signal.

500

(6.6VDC, 1.1Vp-p)

1.2k

The signal advanced for 200ns from

147

49

30k

YOUT is output. The delay time versus

YIN is determined by the DL setting of

the I2C bus. This output can be turned off

400µA

through the I2C bus.

This output can also be turned off by

YS1, YM, and YS2.

4k

50

I2C bus protocol SCL (Serial Clock) input.
