1.
This input pin is ignored and should be connected to GND if the
XRT75L04D is operating in the HOST Mode
2.
This pin is internally pulled down.

I
Hardware Mode: Receiver Turn ON Input
Host Mode: Serial Data Input:
Function of this pin depends on whether the XRT75L04D is configured to oper-
ate in Hardware mode or Host mode.
In Hardware mode, setting this input pin “High” turns on and enables the
Receivers of all three channels.
N
OTES
:
1.
If the XRT75L04D is configured in HOST mode, this pin functions as
SDI input pin (please refer to the pin description for Microprocessor
Interface)
2.
This pin is internally pulled down.

I
Hardware Mode: RxClk INVERT
Host Mode: Chip Select
:
Function of this pin depends on whether the XRT75L04D is configured to oper-
ate in Hardware mode or Host mode.
In Hardware mode, setting this input pin “High” configures the Receiver Sec-
tion of all channels to invert the RxClk_n output signals and outputs the recov-
ered data via RPOS_n and RNEG_n on the falling edge of RxClk_n.
N
OTE
:
If the XRT75L04D is configured in HOST mode, this pin functions as CS
input pin (please refer to the pin description for Microprocessor
Interface).
85
RxMON/
SDO
I
Hardware Mode: Receive Monitoring Mode
Host Mode: Serial Data Output:
In Hardware mode,
when this pin is tied “High” all 4 channels configure into
monitoring channels. In the monitoring mode, the Receiver is capable of moni-
toring the signals with 20 dB flat loss plus 6 dB cable attenuation. This allows
monitoring very weak signal before declaring LOS.
In HOST Mode each channel can be independently configured to be a monitor-
ing channel by setting the bits in the channel control registers.
N
OTE
:
If the XRT75L04D is configured in HOST mode, this pin functions as
SDO pin (please refer to the pin description for the Microprocessor
Interface).
