CL (low-band chroma) signal mode

CENTER BIAS:

The video low-band chroma signal is input to PBRFC pin. CENTER BIAS expands the input dynamic range

and sets a center DC bias so that the center potential of the SIN signal is 2.94V to allow full input. The input

level and frequency are respectively 1490mVp-p (Max.) and DC is up to 1.5MHz.

GCA:

The GCA amplifier controls the gain of the CL signal input to PBRFC. The gain can be varied from 0.4 to

20.5dB by adjusting the RFCONT voltage from 0 to 3V.

CH/CL DC:

CH/CL DC is a DC bias circuit which operates when the CL signal is output to the DRV. The DC bias potential

is 3V.
