Connor-Winfield announces the release of a new GPS disciplined oscillator, adding to their successful 125 family of GPS driven timing and frequency products.
The FTS125-CTV frequency and time standard module is a TCXO based GPS driven mixed signal phase lock loop providing a 1PPS CMOS output from a Connor-Winfield GPS timing receiver and generating a 10MHz CMOS and 10MHz SINE output from an intrinsically low jitter voltage controlled crystal oscillator. The FTS125 can lock to a 10MHz reference derived from the onboard GPS receiver or to an external 10MHz or 1PPS reference. Alarms are provided to indicate loss-of-lock, holdover, and antenna fault.
The onboard GPS receiver requires an outdoor mounted GPS antenna for 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. 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.
