WSE-40 45Gbit/s Wideband VT/TU Cross-connect
Key Features
• * Multi-purpose SONET/SDH VT/TU and SONET/SDH STS/STM crossconnect
• * With a memory-switch architecture, implements a strictly nonblocking switch that supports a VT/TU level fabric of up to 45 Gbit/s
• * Supports 18 high-speed Enhanced SONET Serial Interface (ESSI) CML links each independently configurable for STS-48/STM-16 at 2.488 Gbit/s or STS-12/STM-4 at 622.08 Mbit/s operation
• * Supports system frame synchronization using an external frame pulse or ESSI smart frame synchronization using the frame boundary of the receive links
• * Compensates for differences in frame boundary arrival times between ingress ports using FIFOs and device level software configurable delay registers
• * Each SONET STS-1 or SDH VC3/VC4-TUG3 may be independently configured as a single unit and/or as a container of VT/TUs. The contents may be switched intact or switched as VT/TUs
• * Allows each SONET VT Group to be independently configured to carry VT1.5, VT2, VT3, or VT6 tributaries
• * Allows each SDH TUG2 to be independently configured to carry TU11, TU12, or TU2 tributaries
• * Provides a device latency of 5.62 (+/-0.17) µs for 2.488 Gbit/s links and 6.21 (+/-0.67) µs for 622 Mbit/s links Supports extraction of the transport overhead (TOH) from the ingress ports (both high and low-speed) as well as the insertion of transport overhead into the egress ports via low bandwidth two-bit 77.76 MHz interfaces
• * Supports a hardware-based Automatic Protection Switching mechanism (MAPS) for centralized link protection control when operating with other Microchip devices such as the PM5369 TUPP-9953
• * Provides fully automatic protection switching for Class 1 protection services including 1+1 protection, UPSR, SNCP, and static mesh protection services
• * Provides hardware assists for Class 2 protection services including 1:N protection, BLSR-2/4, MSSPRING-2/4, and dynamic mesh protection schemes
• * All high-speed ingress and egress links are 1.2 V CML and are ELVDS-compatible with programmable pre-emphasis on transmit, equalization on receive, and support for both AC and DC coupled interfaces
• * Each high-speed link supports SONET/SDH framed or unframed PRBS-23 or PRBS-7 generation and monitoring for off-line link verification
• * Configured, controlled, and monitored using a generic 32-bit microprocessor interface
• * Provides a standard 5-signal IEEE 1149.1 JTAG test port for boundary scan test purposes
• * Implemented in 1.2 V core and 2.5 V I/O 0.13µm CMOS technology. Inputs are 3.3 V tolerant
• * Packaged in a 672-ball FCBGA top-hat, 27 mm x 27mm
