MtronPTI
Applications Note:
The MtronPTI M310x series of voltage controlled cystal oscillators, featuring
QiK Chip
TM
technology, pro-
vides 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 suit-
able 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 six-pad or nine-pad, 5x7x1.9 mm, leadless,
ceramic, surface mount package (see page 4, N package drawing) that is RoHS and +260°C reflow compat-
ible, (no PCB traces should be located directly under the 5x7 product). 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.

Product Description
The M310x series of VCXO’s is designed with a hermetically sealed high precision AT cut quartz crystal,
combined with our QiK Chip
TM
technology. This combination provides an industry setting 0.35 ps RMS jitter
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.
