General Description
• Up to 90°C Case Temperature
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
• On Chip Termination for all

user can select between 180-195MHz
or 719-781MHz PECL reference clock
inputs. The input serial data sampling
point voltage threshold can be adjusted.
Additional features include a parity bit
(PARITY±) that is clocked out with the
16 parallel data, Bit Order Swap
(BITORDER) and Data Polarity Invert
(DINVERT). To assist in monitoring
device operation a Loss-of-Lock
(LOLN) alarm and no reference clock
(NOREFN) alarm are provided. The
device is packaged in a modified 90ball, Ball Grid Array (BGA).
