GPS-TCXO Series
GPS Synchronized TCXO Module
March 2014
PRELIMINARY
• The Pletronics GPS-TCXO Series is a high precision GPS-disciplined
•
•
reference oscillator.
The GPS-TCXO utilizes a high precision TCXO oscillator, synchronized
to the GPS atomic clock.
The GPS-TCXO offers unmatched price and performance over traditional GPS-OCXO reference solutions.
Allan Deviation < 2x10-11 at 25°C.
•
• The GPS-TCXO has a standard LVCMOS output.
• Power is 3.3v.
• The GPS-TCXO has very low power consumption due to its high performance TCXO.
• An ideal solution for low power applications.
• Very low phase noise.
• Available in 10 MHz standard reference oscillator frequency. Contact
Pletronics for additional frequencies.
• Evaluation modules are available.
