Applications
To maintain a fully differential topology in the
transmit path the suggested connection scheme for
the transmit microphones is shown in Figure 8.
However, it is possible to use a single-ended
arrangement as shown in Figure 9 for the transmit
interface. In this case the dynamic range of the
MT9092 is reduced by half. In both figures the output
drivers are connected in a fully differential manner.
The MT9092 is a member of the Mitel family of digital
terminal equipment components. There are two
transmisssion devices which connect directly with
the MT9092 to complete an application; the MT8930
(SNIC) and the MT8971/72 (DSIC/DNIC). An ISDN
4-wire "TE" function is implemented with the
MT8930/MT9092 combination. A 2-wire digital phone
for PABX, key-systems and other proprietary
applications is implemented with the MT8971/72/
MT9092 combination.
Figures 10 and 11 show the 4-wire and 2-wire
applications, respectively.
