 LM98513
Rev 3.3 March 2005
LM98513 Dual-Channel, 10-Bit, 50 MSPS Copier Signal Processor
General Description
The LM98513 is a fully integrated, high performance 10-Bit, 50
MSPS CCD signal processing solution for digital copiers and
scanners. High-speed signal throughput is achieved with an
innovative 2-channel architecture including sample and hold,
programmable gain and offset correction and analog-to-digital
conversion. The fully differential processing channels show
exceptional noise immunity, having a very low noise floor of -
68dB each. The fast, temperature stable, 8 bit programmable
gain amplifiers are linear-in-dB which enables fine adjustments
to the signal gain and minimizes cross-channel gain error
caused by mismatch in the CCD output circuitry. The
independently controlled offset correction circuits utilize 8-bit
offset DACs to correct signal and cross-channel offsets. The 10-
bit analog-to-digital converters have excellent dynamic
performance making the LM98513 transparent in the image
reproduction chain.
