GPS Disciplined Oscillator includes holdover functionality.
May 27, 2010 -
Providing 1 PPS CMOS output, Model FTS375 generates 10 MHz CMOS and 10 MHz SINE output from intrinsically low jitter voltage controlled crystal oscillator. Mixed signal, phase lock loop device can lock to 10 MHz reference derived from on-board GPS receiver, or to external 10 MHz or 1 PPS reference. Alarms are provided to indicate Loss-of-Lock, Holdover, and Antenna Fault. Housed in 3.937 x 1.969 x 0.708 in. package, device operates from +3.3 V supply at temperatures from 0-70°C.

Connor-Winfield's New TiMax FTS375 GPS Disciplined Oscillator with Holdover and Exceptionally Low Jitter Ideal for High Precision GPS Based Timing Applications
Aurora, IL - Connor-Winfield Corporation announces the release of a new high performance GPS disciplined oscillator, adding to the successful line of GPS driven timing and frequency products. The FTS375 is an OCXO based module that offers superior timing and frequency characteristics with outstanding phase noise and holdover in a compact, cost-effective design.
Connor-Winfield's new FTS375 is a GPS driven, mixed signal phase lock loop, providing a 1 PPS CMOS output and generating a 10 MHz CMOS and 10 MHz SINE output from an intrinsically low jitter voltage controlled crystal oscillator. The FTS375 can lock to a 10 MHz reference derived from the on-board GPS receiver, or to an external 10 MHz or 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 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 and can be used to access GPS timestamp information or to verify that the receiver has recovered from an alarm condition.
The FTS375's flexibility in configuration and minimal cost, minimal space design make it ideal for use radio base stations, digital video broadcast equipment, 3G and WiMax base stations, synchronization source applications, and power, utilities and public service applications.
