Preliminary Data Sheet
VSC8163
Features
General Description
ating at a 2.48832Gb/s data rate. The internal clock generator uses a Phase-Locked Loop (PLL) to multiply
either a 77.76MHz or 155.52MHz reference clock in order to provide the 2.48832GHz clock for internal logic
and output retiming. The 16-bit parallel interface incorporates an on-board FIFO, eliminating loop timing
design issues by providing a flexible parallel timing architecture. The device operates using a +3.3V power sup-
ply, and is packaged in a thermally-enhanced plastic package. The thermal performance of the 128PQFP allows
the use of the VSC8163 without a heat sink under most thermal conditions.
