FEATURES

DESCRIPTION

The SA3488 is a non-blocking digital

switching matrix that is capable of routing

256 input channels to any of 256 output

channels. Data is fed into and out of the

device via eight serial PCM input and

output channels at 2MBits/sec. The device

can connect or disconnect each input

channel with any output channel, as well as

carry out other functions which are user

programmable via an eight bit parallel

microprocessor interface.

The SA3488

sees its primary use as a building block in

high volume electronic exchanges, voice

data PABX and other standard data

communications applications. It can be

easily configured for operation in PCM 24

or PCM 30 formats.
