PM5377 Overview
PM5377 TSE 240 Released Single Chip 96-Port STS-1/STM-0 Cross-Connect.
PM5377 Key Features
- Implements a 240G memory switch fabric with STS-1/AU-3 switching granularity
- 96 ingress and 96 egress STS48/STS-12 ports for a maximum of 4608 STS-1/AU-3 streams in a single device
- Supports a single-stage, anycast switching capacity of 240G
- Provides a 108 byte FIFO for each ingress port to support 102 byte maximum skew among the input links (1312 ns for 622 M
- Provides 13 delay management (DM) blocks that can be allocated to a subset of devices ports (1 through 25) as either inp
- Supports ganging of 4 DM blocks to form a delay management group (DMG) capable of processing a STS192 signal
- Each port can be individually configured for 2.488Gbit/s or 622Mbit/s operation. Ingress and egress links of a port can
- Optionally inserts AIS on ingress links that are out-of-frame
- Supports unequipped overwrite, and path AIS overwrite on a per egress port and per egress grain basis
- Implements the ESSI Frame layer
