_______________General Desc ription
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 includ-
ed 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.
