| DATAOUT |
Output |
Delayed data to the pin. When cascading the
ODELAYE5 to the IDELAYE5, DATAOUT should be connected to the
CASC_RETURN pin of the IDELAYE5. |
| CNTVALUEOUT<4:0> |
Output |
The CNTVALUEOUT pins are used for reporting the
current tap value and reads out the amount of taps in the current
delay. |
| TDATAOUT |
Output |
Delayed tristate control connects to the
IOB. |
| CASC_IN |
Input |
Cascade delay from IDELAYE5 CASC_OUT. The CASC_IN
pin is used when cascading the ODELAYE5 delay to the
IDELAYE5. |
| ODATAIN |
Input |
Delayed data to the IOB. |
| CNTVALUEIN<4:0> |
Input |
The CNTVALUEIN pins are used for dynamically
switching the loadable tap value. The CNTVALUEIN is the number of
taps required. |
| CE |
Input |
Clock enable used with INC port to increment
(INC=1) or decrement (INC=0) the delay line. Leaving CE enabled for
multiple CLK cycles will allow consecutive changes in the delay
value. |
| CLK |
Input |
Clock used to sample LOAD, CE, and INC. |
| INC |
Input |
Increment and decrement are controlled by the enable signal (CE).
- INC = 1 increments
- INC = 0 decrements
|
| LOAD |
Input |
Load counter value from the CNTVALUEIN bus when
High. |
| RST |
Input |
The reset pin (RST) is asynchronous with the
CLK. |
| TDATAIN |
Input |
Tristate control input. |
