Extension module CFIP-ASI-EXT with Time Synchronization Interface (TSI)
The CFIP-ASI&TSI-EXT is extension module for CFIP Phoenix C IDU with built-in Timing module
featuring temperature stabilized oscillator (OCXO).
Its function is one-direction distribution of precise time synchronization pulses (1PPS = 1 pulse per
second) and 10MHz precise frequency signal from Master side to Slave side over the link. The CFIP-
ASI&TSI-EXT requires external source of precise time synchronization pulses. External source has to
support pulse stability 10e-8 or better.
The source of precise time is taken from TSI1/1PPS input port. If the Timing module recognizes stable
reference input signal then the Timing module synchronizes to this input signal. If the source signal is
not presented or it is not stable enough
,
the Timing module will switch to "holdover" mode. In this
mode the Timing module is able to operate as standalone and hold and generate both 1PPS and
10MHz signal with precision of 10e-8. This signal is transmitted to the Master IDU. The IDU
’
s internal
clock is synchronized with this signal. Then this signal is re-distributed to remote side. Any signal
delays and fluctuations are automatically compensated by built-in precision time algorithm. Complete
and precise synchronization should be available in 10 minutes after turning on the devices. The
synchronization is periodically corrected over time
-
longer run means more precise synchronization.
The long time stable and synchronized frequency is stored into non-volatile memory once per day and
such stored value is used during holdover state for generating stable frequency and time output
signals.
The source of precise time synchronization can be altered by means of GPS. It requires active external
antenna with gain app. 25dB.
