description
The TLV990A is a complete CCD and video signal
processor/digitizer designed for video camcorder
applications. The TLV990A 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 TLV990A 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 TLV990A 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 TLV990A 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.
