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...
