Standard HF PLO

DESCRIPTION

The Standard HF PLO is a 5 MHz to 25 MHz fixed frequency OCXO integrated with a low noise phase lock loop circuit, and is ideal for use as a phase noise clean-up oscillator when phase locking to a more stable source such as a rubidium, cesium or GPS reference. The PLO offers low aging and good temperature stability (when free-running), and a low phase noise floor to -165 dBc/Hz. Frequency dividers are used to prescale the internal HF oscillator and the external reference frequencies to phase lock at a common lower frequency. The standard PLL loop bandwidth options are ≤ 0.1 Hz or ≤ 1 Hz. The PLO is housed in a 2.94” x 2.25” x 0.6” solder sealed steel can, which includes a mounting flange. An internal voltage regulator is provided for excellent power supply line rejection. Please consult the factory if you need any specifications to be modified to better suit your application.
