4.8 Port Timing
4.8.1 XCore I/O AC Characteristics
The Input Valid window parameter relates to the capability of the XS1-L family devices
with regard to the external clock as measured at the L2 device pins. The output
with respect to the incoming data.
4.9 Link Interface Performance
The asynchronous nature of links means that the relative phasing of CLK clocks is
to capture data input to the chip with respect to an external clock source. This
parameter can be calculated as the sum of the input setup time and input hold time
invalid window specifies the time for which an output will be invalid with respect to
the external clock. Note that these parameters are specified as a window rather than
absolute numbers since the L2 provides functionality to delay the incoming clock
For further details on these parameters and on interfacing to higher speed syn-
chronous interfaces see
Notes:
not important in a multi-clock system, providing each meets the required stability
criteria.
