Multiplexer
Vitesse Semiconductor

For optical modules requiring SONET/SDH connections, the Vitesse family of multiplexers and demultiplexers provide multiple data rate coverage with a single 3.3 V power supply.

Key Features
* Compliant with requirements of OIF SFI-4 standard
* Single 3.3 V power supply
* Support for SONET/OC-192, SDH/STM64, 10 GbE, G.975 and G.709 FEC, 10 GbE FEC, and SuperFEC™ systems

Multiplexer (VSC1235 and VSC1237)
* Jitter generation compliant with SONET transmission specifications
* Superior data output eye quality
* High-speed data output logic can be inverted
* High-speed clock output configurable as full rate, half rate, or disabled
* PLL-based architecture supports both counter-clocking and forward-clocking modes
* Bit-order reversal of parallel data bus
* Loss of lock (LOL) alarms
* Case heat sink not required

Demultiplexer (VSC1236 and VSC1238)
* Support for reference clocks with 1/512, 1/16, or 1/64 bit rate
* Offers dynamic voltage threshold adjustment
* Significantly exceeds SONET jitter tolerance specifications
* Support for both RZ and NRZ data formats
* Data output mute, invert, or bit-order reversal
* Selectable sub-rate clock outputs
* Stable clock output modes
* Data parity output available
