The VSC9182 is a 64x64 STS-12/STM-4

Time Slot Interchange Switch IC. A single

device provides 40Gb/s of non-blocking

STS-1 connectivity (768x768 STS-1) with

support for concatenated tributaries. All

STS-12/STM-4 inputs and outputs are

differential serial signals running at 622 Mb/s for efficiency in

switch card and system backplane design. Backplane BER

monitoring and deskew are integrated, and the connection

matrix can be hitlessly reconfigured. Path AIS or UNEQ can

be optionally inserted into all 768 outgoing STS-1 tributaries. A

standard asynchronous CPU interface with event interrupts is

also supported.

GENERAL DESCRIPTION:

VSC9182 - 40G STS-1 Time Slot Interchange

VSC9182 Architectures

Asingle VSC9182 provides sufficient connectivity for a

16x16 OC-48 STS-1 grooming solution. Multiple VSC9182

devices can be used in a three layer Clos architecture to

construct larger switches, up to 1024 OC-48 ports. The

VSC9182 is designed to interface directly with the VSC9186

10Gb/s Pointer Processor & Frame Aligner and VSC9180

2.5Gb/s Backplane Transceiver.
