M310x Series
PECL/LVDS/CML Voltage Controlled Crystal Oscillator – 3.3/2.5/1.8 Volt – 5x7/9x14 mm
Applications Note:
The MtronPTI M310x series of voltage controlled cystal oscillators, featuring
QiK Chip
TM
technology, provides for extremely low
jitter of 0.50 ps RMS, typical at 622.08 MHz. For applications requiring low jitter, frequencies from 150 MHz to 1.4 GHz are
available. LVPECL, LVDS, or CML compatible outputs, as well as operating voltage of 1.8 V, 2.5 V, and 3.3 V are also options on
the M310x.
The M310x is available with a standard APR of ± 50 ppm and ± 100 ppm, over the industrial operating temperature range of -40°C
to +85°C. The M310x achieves this level of performance by utilizing an AT-cut crystal. An enable/disable function is also an
available option on the M310x. An internal 0.01 µF by-pass capacitor also assures optimum noise suppression on the supply
voltage pad.
The superior integrated jitter performance of 0.50 pS RMS, typical at 622.08 MHz, makes the M310x suitable for 10 Gig-E,
broadband networks, network switches, SONET, SDH, SERDES, DWDM, FEC, WLAN, and OC-3 thru OC-192 systems. The
M310x is available in a nine-pad, 5x7x1.9 mm, leadless, ceramic, surface mount package (see page 4, N package drawing) that
is RoHS and +260°C reflow compatible. (No PCB traces should be located directly under the 5x7 product). A six-J-lead, 9x14
mm, ceramic, surface mount package, that is RoHS and +260°C reflow compatible, is also available (see page 4, J package
drawing). Figures 1 and 2 below show load termination conditions for LVPECL and LVDS. The M310x oscillators are backward
compatible to many of the existing products in the industry from Vectron, Epson, and others.
For superior performance in a high frequency clock oscillator, the M310x is a logical choice for designers. The unique design
architecture allows the M310x fast turn around on engineering design samples, as well as production quantities in 2 weeks or less.

M310x Series

Product Dimensions & Pinout Information:
5x7 mm (N) Package
9x14 mm (J) Package
Handling Information:
Although protection circuitry has been designed into the M310 VCXO, 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, 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.
