| DATAOUT |
Output |
Delayed data from the IOB |
| 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. |
| CASC_OUT |
Output |
Cascade delay to ODELAYE5 in cascade. The
CASC_OUT pin is used when cascading from an IDELAYE5 to an ODELAYE5.
The CASC_OUT port of the IDELAYE5 is connected to the CASC_IN of the
ODELAYE5 in cascade. |
| IDATAIN |
Input |
Data from input pin |
| CASC_RETURN |
Input |
Cascade delay returning from the ODELAYE5 DATAOUT
port. This port is used when cascading the ODELAYE5 and
IDELAYE5. |
| 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 in conjunction 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 |
