T7289A

The T7289A DS1 line interface is an intergated circuit that provides a line interface between the DS1 cross connect (DSX) and terminal equipment circuits for cable distances of up to 655 ft.for 22-gauge,plastic,instulated cable (PIC).

Features of the T7289A are:(1)fully integrated DS1 line interface;(2)intended for use in systems that must comply;(3)low power dissipation;(4)on-chip transmit equalization;(5)monplithic clock recovery;(6)high jitter accommodation;(7)excellent transmit template performance;(8)single-rail/dual-rail interface;(9)pin-selectable B8ZS encoder and decoder;(10)loopback modes for fault isolation;(11)multiple link-status and alarm features;(12)minimal external circuitry required.

The absolute maximum ratings of the T7289A can be summarized as:(1):the parameter is dc supply voltage range,the symbol is VDD,the Min is -0.5,the Max is 6.5,the unit is V;(2):the parameter is power dissipation,the symbol is Pdis,the Max is 500,the unit is mW;(3):the parameter is storage temperature range,the symbol is Tstg,the Min is -65,the Max is 125,the unit is .
