SA9101 - PCM FRAME ALIGNER
The SA9101 (Frame Alignment unit for PCM30 Systems) is a C-MOS device which implements the interface to PCM30 Transmission Systems.
In the receive direction, the device performs HDB3 decoding, Frame alignment (selectable between doubleframe and CRC-Multiframe) and extraction of signalling data.
