Product Description
MtronPTI’s M618x Series TCXO’s and TCVCXO’s provide design engineers with low voltage, surface mount products
with extremely tight stability (down to ±0.10 ppm) over temperature and time. Specially processed crystals enable the
M618x to achieve consistent long-term stability and minimal frequency shift after reflow. The low phase noise (-155 dBc/
Hz at 100 kHz) makes the M618x ideal for the design engineer working on all types of systems as the reference timing
source.
Product Applications
The M618x Series is ideally suited for a wide range of applications such as GPS, military, avionics, test and measurement,
WLAN, WiMax base stations, point to point/multi-point radios, medical equipment, frequency synthesis, frequency translation
and land mobile radio. Standard output for the M618x series is HCMOS compatible or clipped sine wave. The product is
ideally suited for battery and remote applications where it draws as little as 1.5 mA of current with a 3.3 volt supply at 13
MHz. This low power consumption provides an advantage over similarly specified ovenized oscillators for power-sensitive
applications. The M618x series offers ±10 ppm minimum pull range with excellent tuning linearity performance for critical
PLL applications. This series is available in selective frequencies from 8 MHz to 52 MHz.

Although protection circuitry has been designed into the M618x 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.
