The Timekeeper oscillator is an OCXO with a fixed output frequency between 5 MHz and 25 MHz, and offers excellent overall performance at a modest cost. The oscillator provides aging rates as low as 3E-10 per day and phase noise floor performance to -165 dBc/Hz. The Timekeeper is housed in a solder sealed steel can which is 2” x 2” x 4”, and includes an SMA(f) connector and 7-pin header on one end.  A low noise voltage regulator is included to minimize power supply line related spurious signals. Please contact technical staff to discuss custom requirements.
