Microwave component specialist distributor, Aspen Electronics has announced the introduction of two new high stability crystal oscillators for high performance, high reliability wireless communications infrastructure applications. Designed and built in Germany by multinational market leader, Vectron International, the C4700 and C4550 crystal oscillators are compact in size and competitive in price. The C4700 is an ultra high stability double ov...

TAIYO YUDEN has announced the availability of its AQ105 series of high-frequency inductors for matching-circuit applications in cell phones, notebook PCs and other wireless-enabled computer and communications devices. AQ105 series inductors employ a proprietary simulation technique that optimally characterizes the device’s structural attributes to produce a typical Q value improvement of 100% or higher, compared to the company’s earlier, indu...

The SMD03025 (3.2 x 2.5 x 0.6 mm) SMD crystals series from specialist distributor PETERMANN-TECHNIK is available in frequencies from 13.0 – 40.0 MHz and in an extended temperature range of up to –40 to +105°C. A frequency tolerance of +-5 ppm at 25°C and a frequency stability +-3 ppm over -10°C to +55°C are possible. The standard aging is +-2 ppm max. after the first year, +-1 ppm is available on request. Larger freque...

The HC-49/US-SMD series metal packaged SMD crystal, is said to be the lowest cost SMD crystal ever. It is available in three package heights with a frequency range from 3.5 to 80.0MHz and an extended temperature range from –40°C +125°C which make it suitable for the use in automotive applications.

Specialist distributor PETERMANN-TECHNIK has announced the Series SXO-0507 SMD clock oscillator in a 7x5mm ceramic package and makes the claim that it is the cheapest clock oscillator ever. It is available in the frequency range 10.0kHz to 175.0MHz in CMOS and 1.0MHz to 800MHz in PECL technology with supply voltages of 1.8, 2.5, 3.3 and 5.0 VDC as well as in extended temperature ranges. Low current consumption and low jitter values are further ke...

Just published by Anglia, the 116 page “Frequency Data Book” describes a host of frequency generators, filters and saw devices in depth. Full data sheets are included for thousands of products including ceramic resonators, crystals, femto clocks, varactor and voltage controlled oscillators, temperature and oven controlled oscillators, and real time clock modules.

Intersil has introduced two micropower real-time clock/calendar devices. The ISL1218 and ISL1220 with on-chip timing and crystal compensation deliver accurate timekeeping with very low power dissipation. The introduction of the devices means that using a lower-cost, 32.768kHz quartz crystal is now a practical and accurate option.

New from microwave and RF component specialist Link Microtek is a family of surface-mount clock oscillators and VCXOs that not only offer high performance but are available with exceptionally short lead times of typically 2 weeks or less.

DT Electronics has made available the Logic Devices LF2242 digital filter as a direct replacement for the Fairchild TMC2242 which is now obsolete. The LF2242 is a 12/16-bit half-band interpolating/decimating digital filter that eliminates the tuning needed with analogue filters.
