Bit 7: Fine Phase Limit Enable (FLEN). This configuration bit enables the fine phase limit specified in the
FINELIM[2:0] field. The fine limit must be disabled for multi-UI jitter tolerance (see PHLIM2 fields). See Section
0 = Disabled
1 = Enabled
Bit 6: No Activity Loss-of-Lock (NALOL). The T0 and the T4 DPLLs can detect that an input clock has no activity
very quickly (within two clock cycles). When NALOL = 0, loss-of-lock is not declared when clock cycles are missing,
and nearest edge locking (
±180°) is used when the clock recovers. This gives tolerance to missing cycles. When
NALOL = 1, loss-of-lock is indicated as soon as no activity is detected, and the device switches to phase/frequency
locking (
±360°). See Sections 7.5.3 and 7.7.5.
0 = No activity does not trigger loss-of-lock.
1 = No activity does trigger loss-of-lock.
Bit 5: Leave set to 1 (test control).
Bits 2 to 0: Fine Phase Limit (FINELIM[2:0]). This field specifies the fine phase limit window, outside of which
loss-of-lock is declared. The FLEN bit enables this feature. The phase of the input clock has to be inside the fine
limit window for two seconds before phase lock is declared. Loss-of-lock is declared immediately if the phase of the
input clock is outside the phase limit window. The default value of 010 is appropriate for most situations. See
Section 7.7.5.
000 = Always indicates loss-of-phase lock—do not use
001 = Small phase limit window,
±45° to ±90°
010 = Normal phase limit window,
±90° to ±180° (default)
100, 101, 110, 111 = Proportionately larger phase limit window
