3-V, 10-Bit, 21-MSPS Area CCD Analog Front End
The TLV990-21 is a complete CCD signal processor/digitizer designed for digital still camera and PC camera applications. The TLV990-21 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 TLV990-21 include: an input clamp circuit for CCD signal, a correlated double sampler (CDS), a prog 611 rammable-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, 21-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 TLV990-21 operates from a single 3-V power supply with a normal power consumption of 150 mW at 21 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 TLV990-21 an ideal CCD signal-processing solution for digital still cameras and 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.
