Notes:

1.The numbers in this table are based on the operating conditions set forth in Table 7 and Table 39.

2.The maximum variable phase shift range, MAX_STEPS, is only valid when the DCM is has no initial fixed phase shifting, that is, the PHASE_SHIFT attribute is set to 0.

3.The DCM_DELAY_STEP values are provided at the bottom of Table 36.
