An important advantage of SecureSync is its unique rugged and flexible modular chassis
that can be configured for your specific needs. Built-in time and frequency functions are
extended with up to six input/output modules.
You can choose from a variety of configurable option cards, each with an assortment of
input/output timing signal types and quantity, including additional 1PPS, 10 MHz, timecode
(IRIG, ASCII, HAVE QUICK), other frequencies (5MHz, 2.048MHz, 1.544MHz, 1MHz), Pre-
cision Timing Protocol (PTP) input/output, multi-Gigabit Ethernet (10/100/1000Base-T),
telecom T1/E1 data rates and multi-network NTP, allowing SecureSync to be customized
for your exact requirements.
A variety of internal oscillators is available, depending on your requirements for holdover
capability and phase noise.
Note: Some of the features described are not available on all SecureSync
variants.
1.2.1 SecureSync's Inputs and Outputs
SecureSync provides multiple outputs for use in networked devices and other syn-
chronized devices. A 10MHz frequency reference provides a precise, disciplined signal for
control systems and transmitters. A 1-Pulse-Per-Second (1PPS) output acts as a precise
metronome, counting off seconds of System Time in the selected timescale (such as UTC,
TAI or GPS); this BNC connector can also be configured to produce IRIG, HaveQuick, or
GPO signals. A multi-I/O 15 pin connector provides default IRIG, ATC, and HaveQuick
Inputs, as well as IRIG, IRIGAM, HaveQuick, and ATC Outputs. These options can all be con-
figured to suit your application (see "Configurable Connectors" on page136).
SecureSync's outputs are driven by its inputs – most notably, Global Navigation Satellite
System (GNSS), or IRIG signal generators and other available input references. GNSS-
equipped SecureSyncs can track up to 72 GNSS satellites simultaneously and synchronize
to the satellite’s atomic clocks. This enables SecureSync-equipped computer networks to
synchronize anywhere on the planet.
