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.
Designed in advanced CMOS process, the TLV990-13 operates from a single 3-V power supply with a normal power consumption of 150 mW at 13 MSPS and 2 mW in power-down mode.
Its single 3-V operation, very low-power consumption, and fully-integrated analog-processing circuitry make the TLV990-13 an ideal CCD signal-processing solution for digital still cameras and PC camera applications.
This device is available in a 48-pin TQFP package and is specified over a -20°C to 75°C operating-temperature range.
