General Description
The FTS125-COO-010.0 MHz frequency and time
standard module is an OCXO based GPS driven,
mixed-signal phase lock loop, providing a 1 PPS CMOS
output from a Connor-Winfield GPS timing receiver and
generating a 10 MHz CMOS and a 10 MHz SINE output
from an intrinsically low jitter voltage controlled crystal
oscillator. The FTS125 can lock to a 10 MHz reference
derived from the on-board GPS receiver or an external
10 MHz reference or to an external 1 PPS reference.
Alarms are provided to indicate Loss-of-Lock, Holdover,
and Antenna Fault. The on-board GPS receiver requires
an outdoor mounted GPS antenna for the best stability
and consistent performance.
The mode control inputs are used to manually
switch between references and/or holdover. The user
application should monitor the alarm outputs and
manually switch modes as needed.
Serial I/O lines provide access to the NMEA messages from the GPS receiver
(referenced in the Connor-Winfield’s Wi125 User Manual. Contact Connor-Winfield Sales
for a copy). The serial I/O lines can be used to access GPS timestamp information, or to
verify that the receiver has recovered from an alarm condition. The reset is used to reset
the GPS receiver (if needed).
