Multi-rate Telecom Backplane SERDES for 2.5 Gbit/s Interconnect
FEATURES
* High performance backplane interface and cross-connect for 2.5G line cards in SONET/SDH systems. * Provides one low-speed parallel TelecomBus interface operating at 32 bits x 77.76 MHz. * Provides three high-speed multi-rate serial backplane interfaces. * Supports CLOS and memory-based switch fabric systems. * Supports linear, UPSR, and BLSR protection strategies. * Provides two pages of connection memory with software and hardware controlled hitless page swaps at frame boundaries. * Provides integrated delay management that allows for arbitrary SONET/SDH frame alignments on each ingress serial link. * High-speed serial RASIO compatible with CML, LVDS, and LVPECL. * Supports nibble and di-bit slicing on 622 Mbit/s links for sliced switching architectures.
PARALLEL PORT FUNCTIONS
* Supports one 32-bit or four 8-bit 77.76 MHz TelecomBus interfaces to SERIAL PORT FUNCTIONS interface with parallel TelecomBus * Supports three RASIO 3G high-speed framers and mappers. serial backplane interfaces for interfacing * Integrated pointer interpreter reduces with SONET/SDH cross-connects, complexity of external framers and framers, mappers, and other mappers by asserting payload, J0, and TBSTM 2488 devices. J1 indications on the outgoing SWITCHING CAPACITY * Each high-speed serial backplane TelecomBus interface. * Implements a 10G memory switch fabric interface is capable of independent * Allows insertion and extraction of TOH with STS-1/AU-3 switching granularity in operation at 4x622 Mbit/s scrambled bytes through a dedicated low speed a single device.

Released PM5309 TBS 2488 Multi-rate Telecom Backplane SERDES for 2.5 Gbit/s Interconnect
* Provides Bit Error Rate (BER) monitoring for all paths received on the TelecomBus interface. * Detects signal degrade (SD-P) and signal fail (SF-P) threshold crossing alarms based on received B3 errors on the TelecomBus interface. * Provides out of frame alignment status information for each ingress port. * Provides per-link SONET-framed and unframed PRBS-23 generation and monitoring for off-line link verification. * Supports frame synchronization using ESSI smart framing or a global frame pulse input signal. * Compensates for in frame boundary arrival times between serial interfaces using FIFOs and device level software configurable delay registers.
GENERAL
* Low power 1.2 V CMOS core with 2.5 V or 3.3 V CMOS/TTL selectable digital I/O. * Generic 16-bit microprocessor bus interface and full suite of interrupts for configuration, control, and status monitoring. * Standard 5-signal IEEE 1149.1 JTAG test port for boundary scan board testing.
ESSI FUNCTIONS
* Automatically frames to the incoming links based on standard A1/A2 framing. * Provides in-service link verification via bit interleaved parity (BIP-8) of the B1 byte. * Optionally generates B1 byte on egress flows.
APPLICATIONS
* Multi-service Provisioning Platforms. * SONET/SDH Digital Cross-connects. * SONET/SDH Add/Drop and Terminal Multiplexers.
