TAFE1040

The TAFE1040 is a complete area CCD analog front-end/digitizer designed for digital camera applications. The TAFE1040 performs all the analog processing functions necessary to maxmize 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 TAFE1040 include:
input clamp circuitry for the CCD and analog video signals, a correlated double sampler (CDS), a programmable
gain amplifier (PGA) with 0 dB 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, 42 MSPS pipeline ADC, a parallel data port
for easy microprocessor interface and 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 TAFE1040 operates from a single 3-V power supply with a normal
power consumption of 180 mW at 42 MSPS and a 2-mW power-down mode.

Very high throughput rate, single 3 V operation, low power consumption, and fully integrated analog processing
circuitry make the TAFE1040 an ideal area CCD signal processing solution for the high-resolution digital camera
and camcorder applications.

The part is available in a 48-pin TQFP package and is specified over 20°C to 75°C operating temperature
range.
