MXO-PLMX

Description

The Multiplied Crystal Oscillator (MXO-PLMX) is a fixed frequency industry leading ultra-low noise OCXO, which is phase locked to an internal HF ULN OCXO, and highly integrated with one or more low noise multiplier stages to create a high performance frequency signal between 200 MHz and 12 GHz.  The MXO-PLMX also provides excellent aging, temperature stability and spectral purity performance. Additional frequency multipliers are used to multiply the internal reference up to phase lock at the internal VHF oscillator frequency. A higher loop bandwidth (~250 Hz, typ) allows the close-in phase noise of the MXO output to be improved since the ultra-low noise HF internal reference provides superior close-in phase noise. The internal ULN reference signal, typically 10 MHz, is also provided and can be used for system synchronization or simply as a clean reference signal when needed. The package varies depending on the number of multiplier stages needed to create the desired frequency and range in size from 5.56” x 4” x 1”, 6.51” x 4” x 1” and 7.46” x 4” x 1”.  The base VHF oscillator frequency and multiple outputs are available as options. (i.e. If ordering a 10 GHz MXO-PLMX, you may also request the 100 MHz, 500 MHz and 5 GHz outputs since they are also being created in the multiplier string.) 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.
