description
The TLV977-10 is a highly-integrated monolithic analog signal processor/digitizer designed to interface the area
charge-coupled device (CCD) sensors in digital camera applications. The TLV977-10 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 TLV977-10 include: input clamp circuitry and 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 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 TLV977-10 operates from a single 3-V power supply with a normal
power consumption of 140 mW and a 2 mW power-down mode.
High throughput rate, single 3-V operation, low power consumption, and fully integrated analog processing
circuitry make the TLV977-10 an ideal CCD sensor interfacing solution for the digital camera applications.
The part is available in a 48-pin TQFP package and is specified over 0
_C to 70_C operating temperature range.
