performance and excellent Phase Noise for your demanding circuit. The M310x is available in LVPECL, LVDS,
or CML output and can be built to a variety of power requirements, 3.3, 2.5, and 1.8V. Tight thermal stability
performance, broad frequency range, in a small 5x7 mm package, and the ability to build and provide product
in approximately 2 weeks, gives the designer a quick, solid foundation to build a solution with.

Handling Information
Although protection circuitry has been designed into the M310x 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.
ESD voltage thresholds are dependent on the circuit parameters used to define the mode. Although no industry-
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.
