High Performance Six Output OCXO in a Compact Package-Band Gap Reference for Improved Stability

Category: References
SKU: NR3626-O

Six Output 10 MHz OCXO Low Phase Noise -PPS Source

NR3626-O


The NR3626-O was designed for those applications requiring a simple, high performance 10 MHz reference in a very small form factor.The NR3626-O uses the same low phase noise OCXOs as our high end GPS locked frequency references as well as the same low noise amplifiers. The frequency is set using a band gap reference to assure excellent temperature stability and minimal noise contribution. Frequency synthesizer option allows frequencies from 14 kHz to 10 MHz. A singe PPS output is available on the rear panel. Power can be AC (with optional power adapter) or from -60 to +60 VDC in a three ranges. The power supply is a shielded, low electromagnetic emission design and provides electrical isolation between the reference and the incoming power.

  • OCXO frequency stability  5ppb/day,  50 ppb/year (optional < 200 ppb/ 10 year projected)
  • PPS option with programmable pulse width
  • self-test provides unit status with indicator and relay contact signal
  • operates from AC power adapter or -60 to +60 VDC in three ranges
  • low phase noise  -145dBc/Hz @ 1 KHz (lower phase noise options available)
  • compact chassis 1.6"H x 6"D x 6" W
  • front panel status indicator for built-in test
