The TLV990-28 is a complete CCD signal  
processor/digitizer designed for digital still  
camera and PC camera applications. The  
TLV990-28 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 TLV990-28 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, 28-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 TLV990-28 operates from a single 3-V power supply with a normal  
power consumption of 150 mW at 28 MSPS and 2 mW in power-down mode.  
Its very high throughput rate, single 3-V operation, very low-power consumption, and fully-integrated  
analog-processing circuitry make the TLV990-28 an ideal CCD signal-processing solution for digital still  
cameras and electronic video camcorder applications.  
This device is available in a 48-pin TQFP package and is specified over a –20°C to 75°C operating-temperature  
range.  
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of  
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
