VSC8173
9.9-10.7Gb/s 16:1 Multiplexer with Clock Generator
GENERAL DESCRIPTION:
The VSC8173 consists of a 16:1 multiplexer and a clock generator
for use in SONET STS-192/SDH STM-64 systems. The 16:1
multiplexer accepts 16 parallel LVDS inputs at a data rate of
622.08Mb/s to 669.31Mb/s. This parallel data stream is then
serialized into a 9.953Gb/s to 10.709Gb/s output. 622MHz data
clock input mode is supported. The clock generator creates the 9.953GHz to 10.709GHz
clock signal used to re-time the transmitted serialized data. The clock generator
requires a 155 to 168MHz or 622 to 670MHz LVPECL reference clock input. To ease
timing constraints on the parallel interface, a 16-bit wide FIFO is included. A divided-by-
16 or divide-by-64 LVDS clock output is available for use as a clock input to the parallel
data source. Additional features include Bit Order Swap and Data Polarity Invert. To
assist in monitoring device operation a Loss-of-Lock alarm and internal temperature
sensing are provided. The device is packaged in a modified 90-Ball Grid Array (BGA).
