• Description: Digital CCD Camera Head Amplifier
• Manufacturer: Sony Corporation

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.
