GENERAL DESCRIPTION
The AD6643 is an 11-bit, 200 MSPS/250 MSPS, dual-channel intermediate
frequency (IF) receiver specifically designed to support multi-antenna systems
in telecommunication applications where high dynamic range performance, low
power, and small size are desired.
The device consists of two high performance analog-to-digital converters
(ADCs) and noise shaping requantizer (NSR) digital blocks. Each ADC consists
of a multistage, differential pipelined architecture with integrated output
error correction logic, and each ADC features a wide bandwidth switched
capacitor sampling network within the first stage of the differential
pipeline. An integrated voltage reference eases design considerations. A duty
cycle stabilizer (DCS) compensates for variations in the ADC clock duty cycle,
allowing the converters to maintain excellent performance.
FEATURES
