AMCC S2052
The S2052 transmitter and receiver chip is designed to perform high-speed serial data transmission over fiber optic or coaxial cable interfaces conforming to the requirements of the ANSI X3T11 Fibre Channel specification. The chip runs at 1250.0, and 1062.5 Mbit/s data rates with associated 10-bit data word. The chip performs parallel-to-serial and serial-to-parallel conversion and framing for block-encoded data.FEATURES

GENERAL DESCRIPTION
The transmitter’s on-chip PLL synthesizes the highspeed clock from a low-speed reference. The receiver’s on-chip PLL synchronizes directly to incoming digital signal to receive the data stream.
