OV Timing
Assertion:
Write to
OV LOW: tSKEW1 + RCLK + tROV
If tSKEW1 is violated there may be 1 added clock: tSKEW1 + 2 RCLK + tROV
De-assertion:
Read Operation to
OV HIGH: tROV
NOTE:
D = Queue Depth
FF Timing
Assertion:
Write Operation to
FF LOW: tWFF
De-assertion:
Read to
FF HIGH: tSKEW1 + tWFF
If tSKEW1 is violated there may be 1 added clock: tSKEW1+WCLK +tWFF
