The TLV990-40 is a complete CCD and video signal processor/digitizer designed for digital still camera and video camcorder applications. The TLV990-40 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 TLV990-40 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, 40-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. Designed in advanced CMOS process, the TLV990-40 operates from a single 3-V power supply with a normal power consumption of 200 mW at 40 MSPS, and 2 mW in power-down mode. Its very high throughput rate, single 3-V operation, very low-power consumption, and fully-integrated analog processing circuitry make the TLV990-40 an ideal CCD and video signal-processing solution for electronic video-camcorder applications. This device is available in a 48-pin TQFP package and is specified over a –20C to 75C operating-temperature range.
