An edge detect circuit detects the relationships between the 125 MHz clock and the
250 MHz rising edge to properly sequence the 16-bit data into the 8-bit output
register.

<variation name>.vhd and includes a PLL. refclk (pclk from the external PHY) drives
the PLL inclock. The PLL has the following outputs:

An optional 62.5 MHz TLP Slow clock is provided for ×1 implementations.
A 125 MHz output derived from the 250 MHz refclk. This 125 MHz PLL output is
used as the clk125_in for the IP core.
A 250 MHz early output that is skewed early in relation to the refclk the 250 MHz
early clock PLL output clocks an 8-bit SDR transmit data output register.
An optional 62.5 MHz TLP Slow clock is provided for ×1 implementations.
