ADN2819/ADN2811 are multirate limiting amplifiers and clock and data recovery ICs with adjustable slice level. They integrate limiting amplifiers, clock and data recovery, and diagnostic functions. The ADN2819 supports multi-rate operation up to 2.7 Gbps, while the ADN2811 supports 2.5/2.7 Gbps data rates only. They exceed all SONET/SDH jitter requirements under all operating conditions.
