Epsilon Clock
Model EC1S

• Antenna propagation delay
compensation
• 1PPS TTL output
• 10 MHz sine wave output
• Time of Day output
• Two auxiliary input/output for a
full range of applicability
• RoHS Compliant

An ovenized oscillator (OCXO) slaved to the GPS input source offers outstanding accuracy and phase
noise. The oscillator in conjunction with the EpsilTime™ smart predictive slaving algorithm mitigates
the effects of inherent GPS noise and complies to the most stringent holdover mode requirements,
such as CDMA-3G, if GPS is lost. Furthermore, the 10 MHz frequency reference is cycle locked to
the 1PPS, meaning that there are always exactly ten million cycles between 1PPS occurrences. This
unique feature is essential to avoid phase jumps and wander between time and frequency references.
Two optional SMA connectors along with a customizable internal module allow a range of dedicated
versions in terms of performance and functionality such as software adjustable frequencies for TV
broadcast, SDH/E1 synchronization for SSU functionality.
Set-up and control of the EC1S is via a serial interface. Status is displayed by 2 LEDs. Alarms
are via relay contacts. The antenna cable delay and the choice of time scale (UTC or GPS) are
programmable.
