The TLV990B is a complete CCD and video signal processor/digitizer designed for video camcorder applications. The TLV990B performs all the analog-processing functions necessary to maximize the dynamic range, corrects various errors associated with the CCD sensor, and then digitizes the results with an on-chip high-speed analog-to-digital converter (ADC). The key components of the TLV990B include: an input clamp circuit for CCD and analog video signals, a correlated double sampler (CDS), a programmable-gain amplifier (PGA) with 0 to 36-dB gain range, two internal digital-to-analog converters (DAC) for automatic or programmable optical black level and offset calibration, a 10-bit, 28-MSPS pipeline ADC, a parallel data port for easy microprocessor interface, a serial port for configuring internal control registers, two additional DACs for external system control, and internal reference voltages.
