The Quartz Crystals for Wireless Applications product range from PETERMANN-TECHNIK contains quartz crystals specially designed for Melexis Wireless ICs (RFIC and RFID). The cost-effective SMD quartz crystal from the HC-49/US-SMD series is mainly used, which can also be supplied with three solder pads (central pin for earthing). By using the 3-pin quartz crystal version, the quartz crystal's EMC performance can be significantly improved. Frequency...

Link Microtek has expanded its range of MtronPTI frequency control products with the addition of the XO5120 series oven controlled crystal oscillator (OCXO), which delivers high stability and excellent phase noise performance over a wide range of operating temperatures. The new device achieves a stability of +/-2ppb over commercial temperatures and +/-3ppb over industrial temperatures, while phase noise is specified as -155dBc/Hz for a 10kHz offs...

Focus EDL has announced that it has added leading frequency management specialist Raltron to its franchise line-up. Established 25 years ago, Raltron is recognised as an industry leader in crystal and oscillator technology producing a very broad range of frequency control products from simple tuning fork crystals up to high stability oven controlled crystal oscillators.

A high dynamic range active upconverting mixer from Linear Technology replaces the best of today’s passive mixers. The LT5579’s wide frequency range of 1.5GHz to 3.8GHz covers the 1.9GHz cellular bands as well as the 2.6GHz and 3.5GHz WiMAX frequency bands. At 2.14GHz, the device offers 27.3dBm Output IP3 linearity and 9.9dB Noise Figure to deliver outstanding transmitter dynamic range. Moreover, the mixer has 2.6dB of conversion gain, the hi...

Just announced by Vectron International is a temperature-compensated crystal oscillator in a package just half the size of its predecessor. The VTM3 TCXO offers equivalent phase noise performance to the proven VTC4 and VTC1 TCXOs but in a smaller package measuring just 3.2mm x 2.5mm.

Silicon Laboratories has announced the expansion of its portfolio of reconfigurable, frequency-agile precision clocks to include a single input, single output jitter-attenuating clock multiplier IC. The new Si5319 Any-Rate Precision Clock is capable of generating any output frequency from either a crystal or reference clock input with 0.3 picoseconds jitter generation.

Intersil has introduced the world’s first full-featured, AC-driven Real Time Clock (RTC) devices. The new ICs will be designed into a wide range of industrial and consumer products, from power meters and security devices to white goods and other high-end appliances that require precise measurement of time. With integrated functionality such as dual alarms, event detection and a “brownout” alert, the new ISL12030 and ISL12032 have the broa...

Precision Devices, the frequency control solutions manufacturer, has today announced a franchise distribution agreement with electronic component distributor Abacus. This agreement enables the Abacus Group to distribute and supply PDI’s frequency control products in the UK and Ireland.

Silicon Laboratories has announced the Si570/1 family, said to be the industry’s first user-programmable crystal oscillators (XO) and voltage-controlled crystal oscillators (VCXO) supporting any-rate frequency synthesis. Using patented DSPLL technology and an industry-standard I2C interface, a single device can generate any output frequency from 10 MHz to 1.4 GHz at jitter levels of 0.3 picoseconds rms. The Si570 Any-Rate XO and Si571 Any-Ra...
