SA9101 Description
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. Wander absorption between the PCM carrier and the system internal highway is performed using an internal 2 frame memory.
SA9101 Key Features
- clock (4096 kHz/ 8192 kHz) Selectable Interface mode (2048/4096 kBit/s) to system internal highway Programmable offsets
