10 Gigabit Ethernet MAC and PHY/OC-192c POS Framer/Mapper
Product Brief
Part Number S19205CBI, Revision 1.4, October 2002
Overview and Applications
The S19205 is a dense VLSI device that integrates a 10GbE MAC, a 64B/66B Physical Coding Sublayer (PCS) and a WAN Interface Sublayer (WIS) as baselined by the IEEE P802.3ae task force. Optionally, it can be configured to perform full-duplex mapping of packets into SONET/SDH payloads at OC-192c rate (POS). When configured for SONET/SDH operation, the S19205 supports Automatic Protection Switching (APS) as required in carrier-class equipment.
The MAC block also integrates an extensive set of counters for network statistics collection in support of RMON and IETF standard MIBs. The MAC supports flow control for both serial LAN (10Gbps) or WAN (9.95Gbps) applications through the 802.3x MAC `PAUSE' functionality.
64B/66B Encoder / Decoder
When configured for Ethernet operation, the PCS sublayer performs frame scrambling and bit ordering before passing data to the WAN Interface Sublayer or to the XSBI interface. 64B/66B block coding is used to guarantee run length, transition density and DC balance of the serial data stream. Data frames are delineated using "01" sync header. Control frames are identified with a "10" sync header.
SONET/SDH Processing (WIS)
The S19205 implements SONET/SDH processing functions for a single STS-192/STM-64 data stream. The S19205 performs full section, line, and path overhead processing of all defined TOH/POH bytes, including framing, scrambling/descrambling, alarm signal (AIS) insertion/detection, remote failure insertion/detection (REI/ RDI), section/path trace insertion/capture (J0/J1) and bit interleaved parity (B1/B2/B3) processing. The S19205 provides programmable Signal Fail (SF) and Signal Degrade (SD) thresholds for B2 and B3 monitoring. The S19205 is SONET and SDH standards compliant with Telcordia GR-253, GR-499 and GR-1377, and ANSI T1. 105-1995, and ITU G.707 and G.783.
Line-side Interface
In 10GbE WAN PHY and OC-192c POS mode, the line-side interface supports a 16-bit parallel bus operating at 622.08 MHz, compliant with the OIF SFI-4 and the proposed IEEE P802.3ae XSBI interfaces. In 10GbE LAN PHY mode, the line side interface operates as a XSBI-compliant 16-bit LVDS parallel interface operating at 644.53MHz.
System Interface
A 64-bit, 200MHz FlexBus-4TM interface is used for transferring packets on the system side. FlexBus-4TM is compliant to the OIF SPI-4 Phase 1 Specification.
POS HDLC Processing
The S19205 can be configured for HDLC processing for STS-192c/ AU-4-64c POS applications. When configured for POS HDLC processing, the S19205's transmit HDLC processor will provide the insertion of HDLC framed packets into the STS SPE. It will perform packet framing, provide interframe fill and TX FIFO error recovery. In addition, it optionally performs payload scrambling (x43 + 1), performs transparency processing as required by RFC 2615 and will optionally generate a 32 bit CRC. The receive HDLC processor provides for the extraction of HDLC frames, transparency removal, de-scrambling (if enabled), FCS error checking and optionally deletes the HDLC address and control fields. The S19205 also provides a robust set of counters and status/control registers for performance monitoring via the microprocessor. It is SONET/SDH standards compliant IETF RFC 1662 and RFC 2615.
Microprocessor Interface
The user of the S19205 can select between an 8-bit asynchronous or a 16-bit synchronous microprocessor interface for device control and monitoring. The interface supports both Intel and Motorola type microprocessors, and is capable of operating in either an interrupt driven or polled-mode configurations.
Applications
* * * * Core switches/routers Multi-service switches MAN switches Direct Mapping of any traffic type in SONET/SDH STS-192c/AU-4-64c payloads
10 Gigabit Ethernet MAC Processing
The 10GbE Medium Access Control block supports full-duplex traffic at 10Gbps rates. In the transmit direction, it performs encapsulation of packets received through the system interface into Ethernet frames. It provides pad insertion to insure a minimum frame length, as well as CRC generation. The MAC processing block also provides for preamble, SFD and IFG generation. In the receive direction, the MAC processing consists of Ethernet framing and CRC validation, as well as monitoring of the size of the received frame.
