MT9173AP集成电路（IC）的电信规格书PDF中文资料

描述 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 a digital output pin indicating the temporal position of the 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.

特性 Features

• Receive sync output pulse

• Full duplex transmission over a single twisted pair

• Selectable 80 or 160 kbit/s line rate
