description
The TLV987 is a highly integrated monolithic analog signal processor/digitizer designed to interface the area
charge-coupled device (CCD) sensors in digital camera applications. The TLV987 performs all the analog
processing functions necessary to maximize the dynamic range, corrects various errors associated with the
CCD sensor, and then converts the results from analog to digital using the on-chip high-speed analog-to-digital
converter (ADC). The key components of the TLV987 include input clamp circuitry, a correlated double sampler
(CDS), and a programmable gain amplifier (PGA). The PGA has 0-dB to 36-dB gain range. In addition, the
TLV987 has two internal digital-to-analog converters (DACs) for automatic or programmable optical black level
and offset calibration. The TLV987 also has two additional DACs for external system control, and internal
reference voltages. The TLV987 has a parallel data port for easy microprocessor interface and a serial port for
configuring internal control registers.
Designed in advanced CMOS process, the TLV987 operates from a single 3-V power supply with a normal
power consumption of 200 mW 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 TLV987 an ideal CCD sensor interfacing solution for digital camera applications.
The device is available in a 48-pin TQFP package and is characterized for operation over 0
°C to 70°C operating
free-air temperature range.
