Input Clock Select/CKIN3 or CKIN4 Active Clock Indicator.
Input
: If manual clock selection is chosen, and if
CKSEL_PIN
= 1, the CKSEL pins control clock selection and
the CKSEL_REG bits are ignored.
If CKSEL_PIN =0, the CKSEL_REG register bits control this
function and these inputs tristate. If configured as inputs, these
pins must not float.
Output:
If auto clock selection is enabled, then they serve as
the CKIN_n active clock indicator.
0 = CKIN3 (CKIN4) is not the active input clock
1 = CKIN3 (CKIN4) is currently the active input to the PLL
The CKn_ACTV_REG bit always reflects the active clock status
for CKIN_n. If CKn_ACTV_PIN = 1, this status will also be
reflected on the CnA pin with active polarity controlled by the
CK_ACTV_POL bit. If CKn_ACTV_PIN = 0, this output tristates.

IANALOG
External Crystal or Reference Clock.
External crystal should be connected to these pins to use inter-
nal oscillator based reference. Refer to Family Reference Man-
ual for interfacing to an external reference. External reference
must be from a high-quality clock source (TCXO, OCXO). Fre-
quency of crystal or external clock is set by the RATE pins.

CKIN4+
CKIN4–
IMULTI
Clock Input 4.
Differential clock input. This input can also be driven with a sin-
gle-ended signal. CKIN4 serves as the frame sync input associ-
ated with the CKIN2 clock when CK_CONFIG_REG =1.

3-Level
External Crystal or Reference Clock Rate.
Three level inputs that select the type and rate of external crys-
tal or reference clock to be applied to the XA/XB port. Refer to
the Family Reference Manual for settings. These pins have both
a weak pull-up and a weak pull-down; they default to M.

CKIN3+
CKIN3–
IMULTI
Clock Input 3.
Differential clock input. This input can also be driven with a sin-
gle-ended signal. CKIN3 serves as the frame sync input associ-
ated with the CKIN1 clock when CK_CONFIG_REG =1.

CKIN1+
CKIN1–
IMULTI
Clock Input 1.
Differential clock input. This input can also be driven with a sin-
gle-ended signal.
