descriptionThe 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 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, 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 –20°C to 75°C operating-temperature
range.
