Multirate Clock and Data Recovery with Limiting Amplifier

Status: Active
Series: MAX3872
RoHS: Unknown
View Datasheet Manufacturer Site View Pricing & Stock

The MAX3872 is a compact, multirate clock and data recovery with limiting amplifier for OC-3, OC-12, OC-24, OC-48, OC-48 with FEC SONET/SDH and Gigabit Ethernet (1.25Gbps/2.5Gbps) applications. Without using an external reference clock, the fully integrated phase-locked loop (PLL) recovers a synchronous clock signal from the serial NRZ data input. The input data is then retimed by the recovered clock, providing a clean data output. An additional serial input (SLBI±) is available for system loopback diagnostic testing. Alternatively, this input can be connected to a reference clock to maintain a valid clock output in the absence of data transitions. The device also includes a loss-of-lock (active-low LOL) output. The MAX3872 contains a vertical threshold control to compensate for optical noise due to EDFAs in DWDM transmission systems. The recovered data and clock outputs are CML with on-chip 50Ω back termination on each line. Its jitter performance exceeds all SONET/SDH specifications. The MAX3872 operates from a single +3.3V supply and typically consumes 580mW. It is available in a 5mm x 5mm 32-pin thin QFN with exposed-pad package and operates over a -40°C to +85°C temperature range.
