DESCRIPTION

· The FTS125-CTV-010.0 MHz Frequency and Time Standard module is a TCXO GPS driven, mixed-signal phase lock loop, providing a 1 PPS CMOS output and generating a 10 MHz CMOS and a 10 MHz SINE output from a low jitter voltage controlled crystal oscillator.

FEATURES

· Phase locked 10 MHz output
· 1 PPS output
· 3 selectable references: GPS, External 10 MHz or External 1 PPS
· Holdover
· Three alarm outputs: Loss-of-Lock, Holdover and Antenna Fault
· Serial input and output ports (GPS receiver)
· Master reset
· +3.3 Volt power supply
· Commercial Temp (0-70° C)
· Meets ITU-T G.811 and ETSI-PRC Wander Generation Mask
· MCX GPS Antenna Connection
· Fixed Position Unit
· Package: 32-pin Through-Hole
· Physical Dimensions: 4.15” x 3.3” x 0.718”

APPLICATIONS

· 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. 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.
