QiK Chip™
Product Description
The multiple frequency VCXO utilizes MtronPTI’s Qik Chip
TM
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 Chip
TM
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
5x7 mm, 3.3/2.5/1.8 Volt, LVPECL/LVDS/CML/HCMOS Output
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.
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.
