Ultra stable TCXO from Precision Devices targets femtocells and base stations
Precision Devices (www.pdixtal.com) has announced the TS05, an ultra stable temperature compensated crystal oscillator (TCXO) in a 5mm by 3.2mm by 1.5mm package. The TS05 provides exceptional stability of only ±0.2ppm over an operating temperature range of -40°C to +85°C. When operating over a restricted temperature range of -10°C to 70°C, stability is even lower at ±0.1ppm.
Stability is ±0.05ppm for supply voltage variations up to 5%, and for load variations up to 10%. With aging, the maximum change is only ±0.5ppm per year, to ensure reliable long-term performance.
The new oscillator has excellent phase noise characteristics. At a frequency of 26MHz, typical phase noise figures are -117dBc/Hz at an offset of 100Hz, -138dBc/Hz at an offset of 1kHz and -152dBc/Hz at an offset of 10kHz.
Targeted at femtocell and base station applications, the TS05 covers the frequency range from 10MHz to 52MHz.
The oscillator operates from a 3V supply voltage, and draws 2mA current when generating a clipped sinewave output, and 4mA when generating a CMOS squarewave output.
The new TS05 precision oscillator can be supplied in 1,000 units on tape and reel. It is available immediately from Precision Devices and through distribution and representative partners across the world.
