Description

LPn: Loopback Select 7~0

In hardware control mode, pin LPn configures the corresponding channel in different loopback mode, as

follows:

ADn: Address/Data Bus 7~0

In multiplexed host mode, these pins are the multiplexed bi-directional address/data bus.

In serial host mode, these pins should be grounded.

MCn: Performance Monitor Configuration 3~0

In hardware control mode, A4 must be connected to GND. MC[3:0] are used to select one transmitter or

receiver of channel 1 to 7 for non-intrusive monitoring. Channel 0 is used as the monitoring channel. If a

transmitter is monitored, signals on the corresponding pins TTIPn and TRINGn are internally transmitted

to RTIP0 and RRING0. If a receiver is monitored, signals on the corresponding pins RTIPn and RRINGn

are internally transmitted to RTIP0 and RRING0. The monitored is then output to RDP0 and RDN0 pins.

In host mode operation, the signals monitored by channel 0 can be routed to TTIP0/RING0 by activating

the remote loopback in this channel. Refer to 2.19 G.772 Monitoring for more details.

Performance Monitor Configuration determined by MC[3:0] is shown below. Note that if MC[2:0] = 000, the

device is in normal operation of all the channels.

An: Address Bus 4~0

When pin MODE1 is low, the parallel host interface operates with separate address and data bus. In this

mode, the signal on this pin is the address bus of the host interface.

E14 Pulling this pin low can drive all driver output into high-Z for redundancy application without external

mechanical relays. In this condition, all other internal circuits remain active.
