M-986-2A1
Overview
40-pin plastic DIP 44-pin PLCC.
- Direct A-Law or ยต-Law PCM digital input
- 2.048 Mb/s clocking
- Operates with standard codecs for analog interfacing
- Microprocessor read/write interface
- Binary or 2-of-6 data formats
- Dual-channel
- 5 volt power Description The M-986-2A1 dual channel MF Transceiver contains all the logic necessary to transmit and receive (North American) CCITT Region 1 multifrequency signals on one integrated circuit (IC). Operating with a 20.48 MHz crystal, the M-986 is capable of providing a direct digital interface to a mlaw or A-law encoded PCM digital input. Each channel can be connected to an analog source using a coderdecoder (codec) as shown in the Block Diagram below. The M-986 is configured and controlled through an integral coprocessor port.
