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.
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 in
Mitel’s ISO
2
-CMOS process.
