Texas Instruments VSP01M01ZWD

Description
The VSP01M01 and VSP01M02 are mixed-signal ICs for charge-coupled device (CCD) signal processing. They feature a built-in CCD timing generator, analog-to-digital converter (ADC), and CCD vertical driver. The AFE CCD channel uses correlated double sampling to extract image information from the CCD output signal. Signal paths have gains ranging from -9 dB to 44 dB. The black level clamping circuit enables accurate black reference level and quick black level recovery after gain changes. An input signal clamp with CDS offset adjustment function is available. The system synchronizes the master clock, horizontal driver (HD), and vertical driver (VD). The VSP01M01 and VSP01M02 support all signal terminals required by CCD architecture. The RG driver, HG driver, and vertical drivers synchronize the ADC clock phase to realize ideal performance.
