General Description
The VSC8131 multiplexes 32 TTL compatible 77.76Mb/s Parallel Data Inputs (D0-D31) into a single
LVPECL 2.488 Gb/s serial output (DO+) for use in SONET STS-48/SDH STM-16 systems. An integrated
Clock Multiplier Unit (CMU) generates a LVPECL 2.488 GHz clock signal (CO+
) from an externally supplied
LVPECL compliant 77.76MHz reference clock (REFCLK+) which is
used to retime the transmitted serialized data.
A Divide-by-32 TTL clock output (CK78OUT) is used as a clock input (CK78IN) for timing of the parallel data
inputs. Parity Checking (PARBIT) is performed on the incoming data with a selectable even or odd TTL parity mode
input (PARMODE) and a TTL Parity Error (PARERR) output. A TTL Loss Of Lock (LOL) output indicator is used to
report the loss of the REFCLK+ or for conditions resulting in the CMU losing lock to incoming clock.
