ISO2-CMOS ST-BUS ™ FAMILY MT9173/74 Digital Subscriber Interface Circuit with RxSB Digital Network Interface Circuit with RxSB
●Description
■The MT9173 (DSIC) and MT9174 (DNIC) are functionally identical to the MT9171/72 except for the addition of one feature. The MT9173/74 include adigital output pin indicating the temporal position ofthe received "SYNC" bit of the biphase transmission. This feature is especially useful for systems such as PCS wireless base station applications requiring close synchronization between microcells.
■The MT9173 and MT9174 are identical except for the MT9173 having a shorter loop reach. The generic "DNIC" will be used to reference both devices unless otherwise noted. The MT9173/74 are fabricated inZarlink's ISO²-CMOS process.
●Features
■Receive sync output pulse
■Full duplex transmission over a single twisted pair
■Selectable 80 or 160 kbit/s line rate
■Adaptive echo cancellation
■Up to 3km (9173) and 4 km (9174) loop reach
■ISDN compatible (2B+D) data format
■Transparent modem capability
■Frame synchronization and clock extraction
■Zarlink ST-BUS compatible
■Low power (typically 50 mW), single 5V supply
