Texas Instruments LM98714 3 Ch 16-Bit 45 MSPS Digital Copier AFE w/ Integrated CCD/CIS Sensor Timing Generator & LVDS Output LM98714BCMT/NOPB

The LM98714BCMT/NOPB is a high-performance, fully integrated analog front end (AFE) designed for digital color copiers and scanners. It features three channels with 16-bit resolution and a sampling rate of 45 MSPS, making it suitable for high-speed image processing applications. The device employs an innovative architecture that includes Correlated Double Sampling (CDS) for CCD arrays and Sample and Hold (S/H) inputs for Contact Image Sensors (CIS) and CMOS image sensors. This AFE incorporates programmable gain amplifiers (PGA) with 256 gain steps, allowing for a gain range of 0.7 to 7.84x, and independent gain and offset correction for each channel. The integrated timing generator supports flexible operation with both LVDS and CMOS output options. The device operates with a supply voltage of 3.3 V and has a low noise floor of -74 dB, ensuring high-quality image reproduction. It is packaged in a 48-pin TSSOP and is rated for operation in temperatures from 0 to 70¬8C. The LM98714BCMT/NOPB is ideal for applications requiring precise image processing and high-speed data conversion.
