DS3 Reference Clock Input/SFM Synthesizer Clock Output:
The function of this chip depends upon whether or not the XRT75L03D has
been configured to operate in the SFM Mode.
If NOT operating in the Single-Frequency Mode
If the XRT75L03D has NOT been configured to operate in the SFM Mode, and if
at least one channel of the XRT75L03D is configured in the DS3 Mode, then a
clock signal with a frequency of 44.736 MHz ± 20ppm must be applied to this
input pin.
If the XRT75L03D is not configured to operate in the SFM Mode and none of the
channels are to be operated in the DS3 Mode, tie this input signal to GND.
If operating in the Single-Frequency Mode
If the XRT75L03D is configured to operate in the SFM Mode, and if pin 107
(E3CLK/CLKEN) is pulled to a logic "High", then the SFM Clock Synthesizer
PLL generated line rate clock signal for Channel 1 will be output via this output
pin.
In this mode, this particular output pin can be used by the user's system as a
timing source.

STS-1 Reference Clock Input/12.288MHz SFM Reference Clock Input:
The function of this pin depends upon whether or not the XRT75L03D has been
configured to operate in the SFM Mode.
If NOT operating in the Single-Frequency Mode
If the XRT75L03D has NOT been configured to operate in the SFM Mode and if
at least one channel is intended to operate in the STS-1 Mode, then the user
must supply a clock signal with a frequency of 51.84MHz ± 4.6ppm to this input
pin
If the XRT75L03D is not to be operatedin the SFM Mode and none of the chan-
nels are to be operated in the STS-1 Mode, tie this input signal to GND.
If operating in the Single-Frequency Mode
If the user has configured the XRT75L03D has been configured to operate in
the SFM Mode a clock signal with a frequency of 12.288MHz ± 20ppm MUST
be applied to this input pin. The SFM Synthesizer will then synthesize one of the
appropriate line rate frequencies (e.g., 34.368MHz for E3, 44.736MHz for DS3,
and 51.84MHz for STS-1) based upon this 12.288MHz Reference Clock source.
