SYNCHRONOUS EQUIPMENT
TCXO BASED STRATUM 3 CLOCK UNIT – SY01-S3T
On the picture below it is shown the pin-out for the SY01-S3T. The design is done in such a way that is can support
basically any other pin-out without changes in the hardware. For other pin-out requirement please contact the Raltron.

Description
Holdover Signal -> the output is high when the unit is in holdover mode
Reference 1 Signal -> the output is high when the unit is using the reference 1
Reference 2 Signal -> the output is high when the unit is using the reference 2
Free-run Signal -> the output is high when the unit is in the free run mode
Alarm signal -> the output is high when there is an alarm in the module, alarm
condition is during free-run mode, holdover mode,
Control Input 1 -> the external input for selecting mode of the unit – see table.
Control Input 2 -> the external input for selecting mode of the unit – see table.
PLL Unlocked Signal -> the output is high when the unit is not locked to any of the
references
Ground
Positive Voltage Supply
Synchronized Output -> the output of the synchronized signal, for frequency
range see table below.
Optional Output -> the secondary output of the synchronized signal, for frequency
range see table below.
External Reference 1 Input -> the input signal from reference 1
External Reference 2 Input -> the input signal from reference 2
