In-Circuit Test Input
:
Setting this pin "Low" causes all digital and analog outputs to go into a high-
impedance state to allow for in-circuit testing. For normal operation, set this pin
"High".
N
OTE
:
This pin is internally pulled “High".

HOST/HW
I
HOST/Hardware Mode Select:
Tie this pin “High” to configure the XRT75R03 in HOST mode. Tie this “Low” to
configure in Hardware mode.
When the XRT75R03 is configured in HOST mode, the states of many of the dis-
crete input pins are controlled by internal register bits.
N
OTE
:
This pin is internally pulled up.

Jitter Attenuator Select 0:
In Hardware Mode, this pin along with pin 42 configures the Jitter Attenuator as
shown in the table below.

OTES
:
1.
The setting of these input pins applies globally to all three (3) channels
in the XRT75R03.
This input pin is ignored and should be tied to GND if the XRT75R03 is
configured to operate in the Host Mode.
