Coarse Latency Increment.
A pulse on this pin increases the input to output device latency
by 1/fOSC (approximately 200 ps). Detailed operations and tim-
ing characteristics for this pin may be found in the Any-Rate
Precision Clock Family Reference Manual. There is no limit on
the range of latency adjustment by this method. Pin control is
enabled by setting INCDEC_PIN = 1 (default).
If INCDEC_PIN = 0, this pin is ignored and coarse output
latency is controlled via the CLAT register.
If both INC and DEC are tied high, phase buildout is disabled
and the device maintains a fixed-phase relationship between
the selected input clock and the output clock during an input
clock switch. Detailed operations and timing characteristics for
these pins may be found in the Any-Rate Precision Clock Fam-
ily Reference Manual.
This pin has a weak pull-down.
CKIN1 Active Clock Indicator.
This pin serves as the CKIN1 active clock indicator. The
CK1_ACTV_REG bit always reflects the active clock status for
CKIN1. If CK1_ACTV_PIN = 1, this status will also be reflected
on the C1A pin with active polarity controlled by the
CK_ACTV_POL bit. If CK1_ACTV_PIN = 0, this output tristates.
CKIN2 Active Clock Indicator.
This pin serves as the CKIN2 active clock indicator. The
CK2_ACTV_REG bit always reflects the active clock status for
CKIN_2. If CK2_ACTV_PIN = 1, this status will also be reflected
on the C2A pin with active polarity controlled by the
CK_ACTV_POL bit. If CK2_ACTV_PIN = 0, this output tristates.
Serial Clock.
