Check for Samples: LM97593 FEATURES DESCRIPTION The LM97593 Dual ADC / Digital Tuner / AGC IC is a
two channel digital downconverter (DDC) with
integrated 12-bit analog-to-digital converters (ADCs)
and automatic gain control (AGC). The LM97593
further enhances TI’s Diversity Receiver Chipset
(DRCS) by integrating a wide-bandwidth dual ADC
core with the DDC. The complete DRCS includes one
LM97593 Dual ADC / Digital Tuner / AGC and two
CLC5526 digitally controlled variable gain amplifiers
(DVGAs). This system allows direct IF sampling of
signals up to 300MHz for enhanced receiver
performance and reduced system costs. A block
