description
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 max-
mize 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.
