General Description
In a world where precise timing is critical, the FTS500
Xenith TBR (Time Base Reference) is the ultimate partner
for your DVB/DAB, wireless communications, time-
stamping or any other timing vital application.
The Xenith TBR module is a GPS driven, mixed-signal
phase lock loop, providing a 1 PPS CMOS output and
generating a 10 MHz SINE output from an intrinsically
low jitter voltage controlled crystal oscillator (VCXO).
The 10 MHz output is disciplined from an on-board GPS
receiver, which drives the long term frequency stability.
The on board GPS receiver at the core of the Xenith TBR
is the highly successful and well established CW25 timing
receiver. This GPS engine along with a dual oven system
provides the highest quality timing and synchronization
signals combined with superb holdover characteristics.
The unit is housed in a 106x125x56mm stylishly
designed, strong aluminum enclosure. The 10 MHz and
1 PPS signal are available on BNC connectors. The
antenna input is also a BNC connector and will operate a
5V active antenna. The Xenith TBR requires this antenna
to placed outdoors for best stability and consistent
performance. The Xenith TBR communicates via RS232
and can be operated and monitored through NMEA or
TSIP protocol. The user can observe the status of the
unit, time of day, position and satellite quality information
via either of the two protocols. The unit has a wide DC
power input range, between 8 and 28VDC, via a secure 2
pin Molex type connector. Accessories such as: AC Mains
adaptor (all regions), antenna cable, high performance
outdoor antenna and serial cable are available as a kit or
can be individually purchased as needed.
