description

The TLV990 is a complete CCD and video signal

processor/digitizer designed for video camcorder

applications. The TLV990 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 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.

Designed in advanced CMOS process, the TLV990 operates from a single 3-V power supply with a normal

power consumption of 150 mW at 28 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 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.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
