General Description
The VSC8162 combines a clock recovery unit (CRU) with a 1:16 demultiplexer on a single chip to directly generate 16-bit wide data from an incoming 2.488Gb/s NRZ data stream. An on-chip Phase Locked Loop (PLL) generates a 2.488GHz clock which remains phase locked to the incoming data. The incoming data is retimed and demultiplexed to a 16-bit word. A Loss of Lock (LOL) signal indicates gross conditions where incoming data no longer has sufficient transitions to keep the C...
