description

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 –20°C to 75°C operating-temperature

range.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

†

The test register must be set to 1011 for 40 MSPS operation.
