The new Si51x XO/VCXOs offer excellent value for < 250 MHz applications that require a combination of frequency agility, good jitter performance, high reliability and competitive pricing. These products migrate the oscillator frequency synthesis function to Silicon Labs’ programmable DSPLL IC while simplifying the crystal oscillator manufacturing flow, enabling mass customized XO/VCXOs with low jitter and short, predictable lead times.
The Si51x complement the existing high frequency, ultra low jitter Si53x/5x/7x product family, enabling Silicon Labs to target lower frequency applications with more competitive pricing. This part can be cross-sold with the entire Silicon Labs timing portfolio, including the Si531x/2x/6x jitter attenuating clocks and Si533x/5x any-frequency, any-output clock generators in addition to the Si53x/5x/7x XO/VCXOs.  They also compete against fixed frequency crystal and SAW oscillators, programmable XO/VCXOs and clock IC solutions.

IQD Frequency Products launched a new ultra miniature crystal, the IQXC-26. This ultra miniature 4-pad crystal is housed in a 1.6 x 1.2 x 0.4mm ceramic package which has a seamed sealed metal lid. This lid is grounded in order to reduce the effects of EMC radiation. This makes the IQXC-26 ideal for use in all wireless based applications. The IQXC-26 is available at any frequency from 26.0 to 80.0MHz, all operating in the fundamental mode. This frequency range covers the required frequency bands for the majority of RF chipsets. The maximum operating temperature range available is -40 to +85 degrees C and frequency stabilities can be as low as +/-10ppm. The IQXC-26 can also be used in medical monitoring equipment, computer peripherals & industrial instrumentation.

XL280 Ultra-compact AC/DC power supply family

Ten models deliver output voltages from 12V to 56V, and up to four units can be wired together to increase the total main output power up to 1,015 watts. 
The XL280 Series supplies leverage N2Power’s unique “green packaging technology to deliver more power in less space, while reducing wasted input power and lowering cooling requirements.  N2Power’s patented design leaves the heat in the load, not in the power supply, reducing power consumption, improving reliability and lowering the cost of ownership. 
The XL280 Series delivers 280 watts of output power from just 15.9 square inches of system design real estate.  Very low profile packaging yields more than 13 watts per cubic inch power density in less than 1U, making the system designer’s job much easier.
