Frequency products Keep the noise down
Crystek's CVCO55FL-0183-0219 voltage controlled oscillator (VCO) operates from 183 to 219MHz with a control voltage range of 0.5 to 4.5V. It is ideal for use in applications such as digital radio equipment, fixed wireless access, satellite communications systems and base stations.
Engineered andmanufactured in the USA, this VCO features a typical phase noise of -
123dBc/Hz at 10kHz offset. Output power is typically +8.5dBmand units are housed in an industry-standard 0.5 by 0.5in SMD package. Input voltage is 5.0V, with a maximumcurrent consumption of 25mA. Pulling and pushing areminimized to 0.5MHz and 0.5MHz/V, respectively. Second harmonic suppression is said to be typically -20dBc.
Time to introduce smart batteries
Timing specialist, Cardinal Components, is now a global second source supplier for Cymbet's EnerChip rechargeable solid state battery packaged products. Produced in the USA, EnerChip smart batteries are synergistic with Cardinal’s real time clock products.
CEO of Cardinal, E. Carl Fabend, said:
“EnerChip batteries will be used in threemajor application areas. The first is to supply power backup for Cardinal's real time clock (RTC) products, as well as other RTC devices in the
market. The second is for Cardinal’s line of modules using embedded rechargeable solid state batteries that are RoHS, REACH, and WEEE compliant. The third area is the energy harvesting powermarket, which uses ambient energy sources such as light, vibration,motion, thermal gradients, air and fluid flow and RF induction.”
Cymbet CEO, Bill Priesmeyer, added:
“EnerChip rechargeable solid state batteries are ideal formany of Cardinal’s customers in
TCXOs provide customfrequencies with quick delivery
Fox Electronics has enhanced its XpressO line of low jitter configurable oscillators with the XpressO-TC, a new temperature compensated crystal oscillator
(TCXO) with customfrequencies up to 250MHz. As with all XpressO oscillators, the new TCXOs can be delivered in less than ten working days.
Part of the FXTC-HE73 series, the new oscillators boast a tight
frequency stability of ±2.5ppmacross a temperature range of -40 to 85°C.With customfrequencies up to 250MHz, the new TCXOs are said to offer a significant advantage over traditional TCXOs with a typicalmaximumfrequency of 50 to 60MHz.
The new devices are ideal for applications requiring high
precision and extremely low jitter, includingmedicalmonitoring andmeasurement, telecommunications and networking, as well asmilitary communications.
Samples are available in one to two days.
