Connor-Winﬁeld’s GPS Disciplined

Oscillators (GPSDOs) were created speciﬁcally for

all precision timing and synchronization applications

requiring higher end, cost sensitive solutions. By

combining our uniquely designed GPS timing

receivers with our high-quality oscillators, Connor-

Winﬁeld is able to offer a wide variety of superior,

cost-effective GPS timing solutions. The 125 Series

modules provide customer applications with the

precise timing capabilities needed to optimize critical

system performance.

General Description

The FTS250-010.0M Frequency and Time Standard module is a GPS driven, mixed-signal phase

lock loop, providing a 1 PPS CMOS output from a Connor-Winﬁeld GPS timing receiver. The FTS250

generates a 10 MHz CMOS and a 10 MHz SINE output from an intrinsically low jitter voltage controlled

crystal oscillator. The FTS250 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).
