Condition
Must assert MOD level within this time
period to ensure that the next PSOUT
period gives correct count. Delay is
with respect to rising edge of PSOUT
(previous count).
With respect to rising edge of PSOUT.
This means that PSOUT need not
continue to be asserted after MOD has
given correct count.
1 kHz offset. Depends on PLL loop
gain.
10 kHz offset. Depends on PLL loop
gain.
100 kHz offset
