GPS Disciplined Oscillators
General Description
The FTS125-CTV-010.0 MHz Frequency and Time
2111 Comprehensive Drive
Aurora, Illinois 60505
Phone: 630-851-4722
Fax: 630-851-5040
Standard module is a TCXO 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
www.conwin.com
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).

NOTES:
1. Stresses beyond those listed under “Absolute Maximum Rating” may cause permanent damage to the module.These are stress ratings only and functional operation of the device at these or any other
conditions beyond those indicated under “Operating Specifications” is not implied. Exposure to absolute maximum rated conditions for extended periods may affect device reliability.
2. Requires external regulation and supply decoupling.
3. Cold Power-up.
4. Holdover will be re-calculated with each successful lock.Yearly aging represents 1 continuous year in Holdover.
5. Relative to 25°C.

Reset Generation (I/O pin 10 - RESET)
The power-on-reset for the FTS125 is generated on-board. If it is desired to extend the power-on-reset signal or provide a manual
reset of the GPS receiver, pull this signal low.

Soldering and Cleaning Recommendations
Hand solder, leaded wave solder, and lead-free wave solder processes are recommended for attaching the FTS125 after reflow
processes are complete. Since the FTS125 does not have hermetic enclosure, hand cleaning the leads is recommended and the
module should not be completely immersed.
