- The nominal frequency of
TRACE_CLK
is 200 MHz. If another clock frequency is used, the parameter
C_TRACE_CLK_FREQ_HZ is set from the
connected input clock (by propagation in AMD Vivado™
IP integrator) if possible, but must
otherwise be manually changed accordingly.
- The frequency of
TRACE_CLK_OUT
is TRACE_CLK divided by 2, nominally 100 MHz
with a 90° phase shift, to create a sample point at a stable
point of the outputs. The phase shift can be adjusted manually
with the parameter C_TRACE_CLK_OUT_PHASE if
necessary.
