Description
Indicator output. High output when Hold Over mode is selected by control pins.
Indicator output. High output when Ref 1 mode is selected by control pins.
Indicator output. High output when Ref 2 mode is selected by control pins.
Indicator output. High output when Free Run mode is selected by control pins.
Ground
Alarm output. High output if module is in Free Run, or Hold Over, or LOR, or LOL, or
PLL_TVL mode.
Mode control input
Mode control input
Tuning Voltage Limit alarm output. High output when Sync_Out is near the extreme
10% ranges of the Pull-in/Hold-in range.
Ground
Primary timing output signal. Signal is sychronized to reference.
Ground
Do not connect. It may affect the module adversely if a signal is apllied.
