Hot-selling and scarce ADN2855ACPZ Burst Mode Clock and Data Recovery IC with Deserializer 32-VFQFN spot stock

Product Descriptions

The ADN2855 is a burst mode clock and data recovery ICdesigned for GPON/BPON/GEPON optical line terminal (OLT)receiver applications. The part can operate at 155.52 Mbps,622.08 Mbps, 1244.16 Mbps,or 1250.00 Mbps data rates, selectablevia the I²C interface 

The ADN2855 frequency locks to the OLT reference clock andaligns to the input data within 12 bits of the start of the preamble .The device provides a full rate or an optional half rate outputclock for a double data rate (DDR) interface to an FPGA ordigital ASIC .

All specifications are quoted for −40°C to +85°C ambient temperature, unless otherwise noted . The ADN2855 is available in acompact 5 mm × 5 mm, 32-lead chip scale package .
