Description

RST
ILVCMOS
External Reset.
Active low input that performs external hardware reset of device.
Resets all internal logic to a known state and forces the device reg-
isters to their default value. Clock outputs are disabled during reset.
The part must be programmed after a reset or power-on to get a
clock output. See Family Reference Manual for details.
This pin has a weak pull-up.

NC
No Connection.
Leave floating. Make no external connections to this pin for normal
operation.

INT_C1B
O
LVCMOS
Interrupt/CKIN1 Invalid Indicator.
This pin functions as a device interrupt output or an alarm output for
CKIN1. If used as an interrupt output,
INT_PIN must be set to 1. The
pin functions as a maskable interrupt output with active polarity con-
trolled by the
INT_POL register bit.
If used as an alarm output, the pin functions as a LOS (and option-
ally FOS) alarm indicator for CKIN1. Set
CK1_BAD_PIN = 1 and
INT_PIN =0.
0 = CKIN1 present.
1 = LOS (FOS) on CKIN1.
The active polarity is controlled by
CK_BAD_POL. If no function is
selected, the pin tristates.
Note: Internal register names are indicated by underlined italics, e.g., INT_PIN. See Si5324 Register Map.
