Pin #
Connection
Description
1
Hold Over
Indicator output. High output when Hold Over mode is selected by control pins.
2
Ref 1
Indicator output. High output when Ref 1 mode is selected by control pins.
3
Ref 2
Indicator output. High output when Ref 2 mode is selected by control pins.
4
Free Run
Indicator output. High output when Free Run mode is selected by control pins.
5
GND
Ground
6
Alarm _Out
Alarm output. High output if module is in Free Run, or Hold Over, or LOR.
7
CNTL A
Mode control input
8
CNTL B
Mode control input
9
PLL_Unlock
Indicates that the PLL is not locked to a reference.
10
Tri-State/GND
0 = Normal operation, 1= Tri-State. Pin is pulled low internally.
Ground pin for normal operation.
