TLV990-13PFBG4

AFE Video 1ADC 10Bit 2.5V/3V/3.3V 48Pin TQFP

description

The TLV990-13 is a complete CCD signal processor/digitizer designed for digital still camera and PC camera applications. The TLV990-13 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 TLV990-13 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, 13-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.
