Low cost SMD crystal is good between -40 +125°C
Petermann-Technik's SMD crystal in a metal package, the HC-49/US-SMD series, is the lowest cost SMD package and now also available in the extended temperature range of –40°C to +125°C. The 3pad package is new. The 3rd pad can be connected to ground. This package grounding has the big advantage of EMI reduction and the amelioration of the crystal fixation on the board - 33% more soldering connection than the common 2pad package.
Crystal designed for applications requiring a small SMD solution
The SMD03025 series was developed for applications that require a highly stable crystal generator in a very small ceramic SMD package, like for example: Bluetooth, GSM, GPS, WLAN, USB-Sticks, etc.. Frequency tolerances of down to +-5 p.p.m. are possible.

Low-cost automotive SMD-quartz crystals
The product assortment “Automotive SMD-quartz crystals” of PETERMANN-TECHNIK includes low-cost/high-performance SMD-quartz crystals in a series HC-49/US-SMD metal housing with 2 and 3 pins (3-pin housing with grounding pin greatly improves the EMC-behaviour in comparison with a normal 2-pin housing) produced in clean rooms, as well as ceramic housing with the dimensions 7x5, 6x3.5 5x3.2, and 3.2x2.5 mm.
40 MHz fundamental quartz oscillator
The product range of PETERMANN-TECHNIK includes a 40 MHz fundamental quartz oscillator in a 5.0 x 3.2 x 1.2 mm ceramic package, with a supply voltage of 1.8 VDC, which is especially adapted to the Atheros WLAN 802.11n IC AR9220-AC1E-R (2.4 / 5GHz 2x2 IC AR9220 Processor MAC/BB/Radio for WLAN BGA337).
National Semiconductor’s Clock Jitter Cleaners Eliminate Need for VCXO Modules
National Semiconductor has introduced the industry’s first family of clock jitter cleaners capable of providing ultra low-noise clocks without external high-performance voltage-controlled crystal oscillator (VCXO) modules. Using a simple external crystal and cascaded PLLatinum architecture, National’s new clock jitter cleaners provide sub-200 femtosecond (fs) root-mean-square (RMS) jitter to improve system performance and accuracy. This leve...
