Oscillators save space for the same
performance
TCXO offers similar phase noise performance to Vectron's proven VTC4 and VTC1 TCXOs in a 50% smaller package.
Vectron International has released its smallest temperature compensated crystal oscillator (TCXO) to date The new VTM3 TCXO offers similar phase noise performance to Vectron's proven VTC4 and VTC1 TCXOs in a 50% smaller package (3.2 x 2.5mm), enabling customers in the communications, industrial, test and military markets to benefit from the flexibility of a smaller, lower power oscillator without compromising the tight stability and superb phase noise performance they have come to expect from Vectron TCXOs

SAW oscillators extend beyond 1GHz
Vectron International has extended the output frequency range of its surface acoustic wave based oscillators beyond the gigahertz barrier.
"Vectron is continually working to combine its investment in innovation and next-generation technology with creative uses of existing technology to develop advanced solutions that meet ongoing demands for smaller, low cost, high performance designs", says Alan Mond, Vice President of Global Sales, Vectron International.
"Our new VTM3 TCXO provides customers with superior phase noise performance and enhanced frequency stability in a smaller footprint, enabling them to lower total cost of ownership, bring products to market faster and achieve their product visions".
A key challenge in miniaturising any oscillator platform is that, typically, oscillator phase noise increases as its size is reduced.

New choke eliminates common mode noise
Pulse's ChipChoke series for USB2.0 standard applications are said to eliminate common mode noise in high-speed networks.
Leveraging advanced crystal design and simulation techniques, Vectron was able to ensure the VTM3 offers phase noise performance comparable to its previous VTC1 and VTC4 generations (with a phase noise floor of -155dBc/Hz) in a significantly smaller package.
At the same time, the new VTM3 improves further on previous TCXO generations by providing enhanced frequency stabilisation in an expanded temperature range (enabling the stabilisation of frequencies between 8 to 45MHz in a temperature range of -30 to +80C at equal to or better than +/-0.5ppm).
The new VTM3 TCXO is optimised for use in a wide range of wireless RF applications, including in GPS, in-car navigation, pilot locator, security/tracking, WLAN, WiMAX and Wi-Fi basestations, Bluetooth, digital cameras, PHS, RFID, test equipment, and wireless meter readers.
Generally available as a fixed-frequency TCXO, the VTM3 can be ordered with a voltage controlled crystal oscillator (VCTCXO) function for applications such as seismic exploration, basestation, video transport and WiMAX timing, where it will be used in a PLL or where the output frequency needs fine tune adjustments.
And, with typical current consumption as low as 1mA, the new VTM3 TCXO is ideally suited for battery powered applications, such as PDAs, satellite radios, mobile TV, point-to-point radio and handsets.
