M21x Series Multiple Frequency Clock Oscillator
5x7 mm, 3.3/2.5/1.8 Volt, LVPECL/LVDS/CML/HCMOS Output
Product Features
* * * * * * Multiple Output Frequencies (2, 3, or 4) - Selectable QiK ChipTM Technology Superior Jitter Performance (less than 0.25 ps RMS, 12 kHz - 20 MHz) SAW replacement - better performance Frequencies from 50 MHz - 1.4 GHz (LVDS/LVPECL/CML) Frequencies from 10 MHz - 150 MHz (HCMOS)
QiK ChipTM
Product Description The multiple frequency oscillator utilizes MtronPTI's Qik ChipTM technology to provide a very low jitter clock for all output frequencies. The M21x is available with up to 4 different frequency outputs from 10MHz through 1.4 GHz. The M21x utilizes the stable fundamental 3rd overtone crystal and the Qik ChipTM IC to provide the wide range of output frequencies. Using this design approach, the M21x provides exceptional performance in frequency stability, jitter, phase noise and long term reliability.
Product Applications

Handling Information Although protection circuitry has been designed into the M21x 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. ESDvoltagethresholdsaredependentonthecircuitparametersusedtodefinethemode.Althoughnoindustrywide standard has been adopted for the CDM, a standard HBM (resistance = 1500 , 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.
