Description
The CXA2056Q is a bipolar IC developed as a head amplifier for digital CCD cameras. This IC provides the following functions: correlated double sampling, AGC for the CCD signal, GCA for the low band chroma signal, AMP for high-band chroma and line signals, A/D sample and hold, blanking, A/D reference voltage, and an output driver.

FEATUREs
• High sensitivity made possible by a high-gain AGC amplifier
• Blanking function provided for the purpose of calibrating the CCD output signal black level
• Regulator output pin provided for A/D converter reference voltage
• Built-in GCA and AMP for amplifying video signals (chroma and line signals) from external sources
• Built-in sample-and-hold circuits for camera signals required by external A/D converters
