VSC8117 - Vitesse Semiconductor

VSC8117 ATM/SONET/SDH 622/155 Mb/s Transceiver Mux/Demux

The VSC8117 is an ATM/SONET/SDH-compatible transceiver that integrates an on-chip clock multiplication unit (CMU) for the high-speed clock, as well as a clock and data recovery (CDR) unit with 8-bit serial-to-parallel and parallel-to-serial data conversion. The phase-locked loop (PLL) clock is used for serialization in the transmit direction (Mux). The recov.
