Product Summary
VSC8141
Multi-Rate 16:1 SONET/SDH Transceiver with Integrated Clock Generator
Features
General Description
The VSC8141 is a SONET/SDH compatible 3.3V multi-rate transceiver with integrated clock generator for
use in SONET/SDH systems operating at OC-48, OC-24, OC-12, OC-3, or Gigabit Ethernet data rates. The
internal clock generator uses a phase-locked loop (PLL) to multiply either a 77.76MHz or 155.52MHz reference
clock for internal logic and output retiming. The 16-bit parallel LVPECL interface incorporates an on-board
FIFO to address loop timing design issues. Facility and Equipment Loopbacks can be configured separately or
simultaneously. The VSC8141 supports 3.3V operation with 2.3 Watts maximum power (1.8 Watts typical) and
is packaged in a thermally-enhanced 128-pin PQFP or 208-pin TBGA package.
