MAX3270

155Mbps/622Mbps Clock Recovery and Data Retiming IC with Fully Integrated Phase Frequency Detector


Please check latest availability status for a specific part variant.

Description

The MAX3270 is a complete Clock Recovery and Data Retiming IC for 155Mbps and 622Mbps SDH/SONET and ATM applications. The MAX3270 meets Bellcore and CCITT jitter tolerance specifications ensuring error-free data recovery. Recovered clock and data are phase aligned using a fully integrated phase-locked loop (PLL). An output frequency monitor (FM) is included to detect loss of PLL acquisition or a loss of input data.

The MAX3270 has differential ECL input and output interfaces, so it is less susceptible to noise in a high-frequency environment. The fully integrated PLL includes an integrated phase-frequency detector that eliminates the need for external references.
