µPD6464A,6465

VSYT and VPED levels of composite video signal

VPED

VSYT

GND

Match the level output from the VBSI pin in the external video signal mode with the level output from the same

pin in the internal video signal mode.

Input level in external video signal mode (when video signal of 1 Vp-p is input)

5 V

RVCNT

VCNT

VBSI

VBSO

Voltage applied to VCNT pin by RVCNT = 2.5 V

VSYT = 1.0 V clamp input

To input an external video signal with an amplitude of 2 Vp-p, input a 1.0-V clamp signal to VSYT, apply 5.0 V to the

VCNT pin, and set the amplitude of 2 Vp-p by using the “output level control command”.
