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
