The VCS8184 combines a clock recovery unit and data retiming with a 1:16 Demultiplexer on a single chip to directly generate 16-bit wide data from an incoming 11.5Gb/s to 12.5Gb/s data stream, for use in SONET STS-192/ SDH STM-64 systems. An on-chip Phase Locked Loop (PLL) with Voltage Controlled Oscillator (VCO) generates a 11.5GHz to 12.5GHz clock, which remains phase locked to the incoming data. The incoming data is retimed and Demultiplexer into 16 parallel outputs. It features a highly flexible reference clock input scheme. The
