14-CHANNEL T1/E1/J1 SHORT-HAUL LINE INTERFACE UNIT
REV. 1.0.1
5.2
The XRT83VSH314 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 24
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 12
