STS-12/STM-4 OR STS-3/STM-1 SONET/SDH TRANSCEIVER
REV. 1.0.3

FEATURES
Targeted for SONET STS-12/STS-3 and SDH STM-4/STM-1 Applications
Selectable full duplex operation between STS-12/STM-4 standard rate of 622.08 Mbps or STS-3/STM-1
155.52 Mbps
Single-chip fully integrated solution containing parallel-to-serial converter, clock multiplier unit (CMU), serial-
to-parallel converter, clock data recovery (CDR) functions, and a SONET/SDH frame and byte boundary
detection circuit
Ability to disable and bypass onchip CDR for external based received reference clock recovery thru
Differential LVPECL input pins XRXCLKIP/N
8-bit LVTTL parallel data bus paths running at 77.76 Mbps in STS-12/STM-4 or 19.44 Mbps in STS-3/STM-1
mode of operation
Uses Differential LVPECL or Single-Ended LVTTL CMU reference clock frequencies of either 19.44 MHz or
77.76 MHz for both STS-12/STM-1 or STS-3/STM-1 operations
Optional use of 77.76 MHz Single-Ended LVTTL input for independent CDR reference clock operation
Able to Detect and Recover SONET/SDH frame boundary and byte align received data on the parallel bus
Diagnostics features include LOS monitoring and automatic received data mute upon LOS
Provides Local, Remote and Split Loop-Back modes as well as Loop Timing mode
Optional flexibility to re-configure the transmit parallel bus clock output to a clock input and accept timing
signal from the framer/mapper device to permit the framer/mapper device time domain to be synchronized
with the transceiver transmit timing.
Meets Telcordia, ANSI, Bellcore TR-NWT-000253 and GR-253-CORE, and G.783 ITU-T jitter requirements
Operates at 3.3V with 3.3V I/O
Less than 660mW in STS-3/STM-1 mode or 800mW in STS-12/STM-4 mode Typical Power Dissipation
Package: 10 x 10 x 2.0 mm 100-pin QFP
