Mini SMD Crystal is ideal for wireless applications
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...
Low cost SMD crystal available in three package heights
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.
Low-cost clock oscillator is cheapest available says PETERMANN-TECHNIK
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...

Intersil's Real-Time Clocks can use lower-cost crystals
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.
Surface-mount clock oscillators and VCXOs available in two weeks (or less)
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.
Pin-compatible replacement for obsolete Fairchild TMC2242 filter
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.
Fully Integrated Filter Front End Module For GPS-Equipped Dual-Band CDMA Handsets
Avago Technologies has announced what it says is the first module to combine five individual FBAR (Film Bulk Acoustic Resonator) filters to produce a totally passive solution for dual-band cellular communications with GPS. The ACFM-7101 quintplexer module directs PCS and cellular signals from the same antenna without the use of switches and control logic, eliminating the cost and electrical loss of the switch, as well as routing and matching loss...
