RST - Reset
The reset input pin (RST) is an active-High asynchronous reset. IDELAYCTRL must be
reset after configuration (and the REFCLK signal has stabilized) to ensure proper
IODELAY operation. A reset pulse width T
must be reset after configuration.
REFCLK - Reference Clock
The reference clock (REFCLK) provides a time reference to IDELAYCTRL to calibrate all
IODELAY modules in the same region. This clock must be driven by a global clock buffer
(BUFGCTRL). REFCLK must be F
(IDELAYCTRL_REF_PRECISION) to guarantee a specified IODELAY resolution
(T
PLL, or from the DCM, and must be routed on a global clock buffer.
RDY - Ready
The ready (RDY) signal indicates when the IODELAY modules in the specific region are
calibrated. The RDY signal is deasserted if REFCLK is held High or Low for one clock
period or more. If RDY is deasserted Low, the IDELAYCTRL module must be reset. The
implementation tools allow RDY to be unconnected/ignored.
