MT8930C

CMOS ST-BUS FAMILY MT8930C Subscriber Network Interface Circuit Data Sheet Features ETS 300-012, CCITT I.430 and ANSI T1.605 S/T interface Full-duplex 2B+D, 192 kbit/s transmission Link activation/deactivation D-channel access contention resolution Point-to-point, point-to-multipoint and star configurations Master (NT)/Slave (TE) modes of operation Exceeds loop length requirements Complete loopback testing capabilities On chip HDLC D-channel protocoller 8 bit Motorola/Intel microprocessor interface Controllerless or microprocessor-controlled operation Zarlink ST-BUS interface Low power CMOS technology Single 5 volt power supply The MT8930C Subscriber Network Interface Circuit (SNIC) implements the ETSI ETS 300-012, CCITT I.430 and ANSI T1.605 Recommendations for the ISDN S and T reference points. Providing point-topoint and point-to-multipoint digital transmission, the SNIC may be used at either end of the subscriber line (NT or TE). An HDLC D-channel protocoller is included and controlled through a Motorola/Intel microprocessor port. A controllerless mode allows the SNIC to operate without a microprocessor. The MT8930C is fabricated in Zarlink’s CMOS process.
