CS4804 Datasheet PDF - Applied Micro Circuits Corporation

The S4804 is a highly-integrated VLSI device that provides full-duplex mapping of packets or ATM cells to SONET/SDH payloads. It provides support for both uni-directional and bi-directional rings.

FEATUREs
• Provides a SONET/SDH STS-48/STM-16, 4 STS-12/STM- 4, or 16 STS-3/STM-1 line interfaces.
• STS-48/STM-16 data stream supports a single STS-48c/AU-4-16c, or any valid combination of STS-12c/AU-4-4c and/or STS-3c/AU-4 SONET/SDH payloads.
• Each STS-12/STM-4 data stream supports a single STS- 12c/AU-4-4c or 4 STS-3c/AU-4 SONET/SDH payloads.
• Each STS-3/STM-1 data stream supports a single STS-3c/AU-4 SONET/SDH payload.
• Supports mixed STS-3 / STS-12 line rates
• Provides full-duplex mapping of ATM cells or packets in each payload tributary.
• Supports termination of mixed ATM and POS tributaries.
• Terminates/generates SONET/SDH section, line, and path layers with transport/section E1, E2, F1, and DCC overhead interfaces in both transmit and receive directions.
• APS port to support protection-switching configurations between two RHINE devices.
• 16-bit, bus interface at 155 MHz for STS-48/STM-16 mode, or serial interfaces operating at 622/155 MHz for STS-12/3 (STM-4/1) modes on the line side.
• 32-bit, parallel interface (FlexBus-3TM) operating at 100 MHz on the system side.
• .25 micron, 2.5V core, and 3.3V tolerant I/O.
• Packaged in a 624 Pin CBGA.
