The multiple frequency VCXO utilizes MtronPTI’s Qik ChipTM technology to provide a very low jitter clock for all
output frequencies. The M31x is available with up to 4 different frequency outputs from 10MHz through 1.4
GHz. Unlike traditional VCXO’s where multiple crystals are required for each frequency, the M31x utilizes a
rock solid fundamental 3rd overtone crystal and the Qik ChipTM IC to provide the wide range of output frequen-
cies. Using this design approach, the M31x provides exceptional performance in frequency stability, jitter,
phase noise and long term reliability.

Handling Information
Quality Parameters
Part Marking Guide
Although protection circuitry has been designed into the M31x oscillator, proper precautions should be taken to
avoid exposure to electrostatic discharge (ESD) during handling and mounting. MtronPTI utilizes a human-body
model (HBM) and a charged-device model (CDM) for ESD-susceptibility testing and protection design evaluation.
ESDvoltagethresholdsaredependentonthecircuitparametersusedtodenethemode.Althoughnoindustry-
wide standard has been adopted for the CDM, a standard HBM (resistance = 1500 Ω, capacitance = 100 pF) is
widely used and therefore can be used for comparison purposes. The HBM ESD threshold presented here was
obtained using these circuit parameters.
