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.
