Bit D3 - LOSMUT(n) (Recovered Data MUTing dur-
ing LOS Condition - Channel(n))
This Read/Write bit-field is used to configure Chan-
nel(n) in the XRT7302 to NOT output any recovered
data from the line while it is declaring an LOS condi-
tion.
Writing a "0" to this bit-field configures the chip to out-
put recovered data even while the XRT7302 is declar-
ing an LOS condition. Writing a "1" to this bit-field
configures the chip to NOT output the recovered data
while an LOS condition is being declared.
N
OTE
:
In this mode, RPOS(n) and RNEG(n) is set to "0"
asynchronously
Bit D2 - RxOFF(n) (Receive Section - Shut OFF Se-
lect)
This Read/Write bit-field is used to shut-off the Re-
ceive Section of Channel(n) in the XRT7302. The
purpose of this feature is to permit conservation of
power consumption when this is the back-up device
in a Redundancy System.
Writing a "1" into this bit-field shuts off the Receive
Section of Channel(n). Writing a "0" into this bit-field
turns on the Receive Section of Channel(n).
Bit D1 - RxClk(n)INV (Invert RxClk(n))
This Read/Write bit-field is used to configure the Re-
ceiver of Channel(n) of the XRT7302) to output the
recovered data on either the rising edge or the falling
edge of the RxClk(n) clock signal.
Writing a "0" to this bit-field configures the Receiver to
output the recovered data on the rising edge of the
RxClk(n) output signal. Writing a "1" to this bit-field
configures the Receiver to output the recovered data
on the falling edge of the RxClk(n) output signal.
Bit D0 - Reserved
This bit-field has no defined functionality.
Command Register CR4-(n)
The bit-format and default values for Command Reg-
ister CR4 are listed below followed by the function of
each of these bit fields.
