LM98714 Three Channel, 16-Bit, 45 MSPS Analog Front End with LVDS/CMOS Output and  
Integrated CCD/CIS Sensor Timing Generator

FEATURES  
DESCRIPTION  
The LM98714 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 Contact Image Sensors and CMOS

image sensors). The signal paths utilize  
8 bit  
Digital Black Level Correction Loop for Each  
Channel  
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 inputs. The signals are then routed to a  
45MHz high performance analog-to-digital converter  
(ADC). The fully differential processing channel  
shows exceptional noise immunity, having a very low  
noise floor of –74dB. The 16-bit ADC has excellent  
dynamic performance making the LM98714  
transparent in the image reproduction chain.
