MCn: Performance Monitor Configuration 4~0
In hardware control mode, A4 must be connected to GND. MC[3:0] are used to select one
transmitter or receiver of the 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 clock and data recovery circuit in receiver 0 can then output the monitored clock to pin
RCLK0 as well as the monitored data to RDP0 and RDN0 pins. The signals monitored by
channel 0 can be routed to TTIP0/TRING0 by activating the remote loopback in this channel.
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.
OE: Output Driver Enable
Pulling this pin to low can make all driver output into high impedance state immediately for
redundancy application without external mechanical relays. In this condition, all the other
internal circuits remain active.
CLKE: Clock Edge Select
The signal on this pin determines the active edge of RCLKn and SCLK in clock recovery mode,
or determines the active level of RDPn and RDNn in the data recovery mode. (Refer to
Functional Description and Table-2).
