LM98722  
SNAS487B –SEPTEMBER 2009–REVISED MARCH 2015  
LM98722 3 Channel, 16-Bit, 45 MSPS Analog Front End with LVDS/CMOS Output,  
Integrated CCD/CIS Sensor Timing Generator, and Spread Spectrum Clock Generation  
1 Features  
3 Description  
The LM98722 is a fully integrated, high performance  
16-Bit, 45 MSPS signal processing solution for digital  
color copiers, scanners, and other image processing  
applications. High-speed signal throughput is  
achieved with an innovative architecture utilizing  
Correlated Double Sampling (CDS), typically  
employed with CCD arrays, or Sample and Hold  
(S/H) inputs (for higher speed CCD or CMOS image  
sensors). The signal paths utilize 8 bit Programmable  
Gain Amplifiers (PGA), a +/-9-Bit offset correction  
DAC and independently controlled Digital Black Level  
correction loops for each input. The PGA and offset  
DAC are programmed independently allowing unique  
values of gain and offset for each of the three analog  
inputs. The signals are then routed to a 45-MHz high  
performance analog-to-digital converter (ADC). The
