Sync signal input for V sync separation.

Input a 2Vp-p Y signal.

Sync signal input for H sync separation.

Input a 2Vp-p Y signal.

Y signal differential waveform output for VM

(Velocity Modulation). (7.1VDC, 2.0Vp-p) The

signal delayed for 250ns from YIN is output.

The delay time from YIN and the differential

coefficient of the output signal vary according to

sharpness f0 control.

Burst gate pulse output.

This pulse is a 0 to 3V positive polarity pulse.

While this pulse is gated near V-Sync for the

CXA2025S, it is constantly output for the

CXA2095S.
