84-Channel T1/E1 Multiplexer/Mapper Applications
The XRT83SH314 has the capability of providing the necessary chip selects for multiple 14-channel LIU
devices. The LIU is responsible for selecting itself, up to 5 additional LIU devices, or all 6 devices
simultaneously for permitting access to internal registers. The state of the chip select output pins is
determined by a chip select decoder controlled by the 3 MSBs of the address bus ADDR[10:8]. Only one LIU
(Master) requires the ADDR[10:8]. The other 5 LIU devices use the 8 LSBs for the direct address bus
ADDR[7:0].
Figure 26
is a simplified block diagram of connecting six 14-channel LIU devices for 84-channel
applications. Selection of the chip select outputs using ADDR[10:8] is shown in
Table 13
