EBO3 Epsilon Board OEM 30 pages

Epsilon Board
Model EBO3

• GPS Clock OEM module
• Variety of external references
o GPS 12 channels reception on L1
(1575 MHz) C/A code
o 1PPS input
o 10 MHz input
o NMEA standard ToD via RS-232
• 1PPS TTL output

The Epsilon Board Model EBO3 provides synchronization solutions with very accurate and stable
time and frequency signals. The high performance and the optimized architecture are well-suited for
transmitter synchronization of Digital Broadcast (DVB-T, DVB-H, DVB-SH, T-DMB, MediaFLO, DAB or
DRM) in SFN modes, or wireless synchronization of BTS (CDMA, TD-SCDMA).
Epsilon Board Model EBO3 is mechanically and electrically compatible with the Epsilon Board Model
EBO2, allowing a smooth transition for those who have already integrated the EBO2 in their design.
The EBO3 can also be provided without a GPS receiver (MFN modes), using an external 1PPS or
other references.

• 10 MHz sine wave output
• NMEA/Time of Day output
• RoHS Compliant

An ovenized oscillator (OCXO) slaved to the input source offers outstanding accuracy and phase
noise. The smart EpsilTimeTM Kalman based algorithm allows intelligent input signal ltering and
provides real adaptability to the quality of the active input reference (GPS, external pps, etc.). In case
of total input reference disruption, the highly stable oscillator allows a very efcient holdover mode
where Time (SFN) and Frequency (MFN & SFN) accuracies are maintained.
