Tiny TCVCXO gets close to oven–controlled crystal stability
on
IQD frequency products have introduced a new range of temperature compensated voltage controlled crystal oscillators (TCVCXO) in a miniature 8-pad 5 x 3.2 mm outline. The IQXT-210 series TCVCXO, offers frequency stability down to ±0.14ppm over the full industrial temperature range of -40 to 85ºC.
Powered from a 3.3V supply the IQXT-210 has a typical current draw of only 12 mA (dependent upon oscillator frequency). The frequency can be specified between 10 MHz to 50 MHz. Initially there are 11 standard frequencies available including 12.8 MHz, 19.2 MHz and 26.0 MHz. Output can be specified as either HCMOS, 15pF load or Clipped Sine, into 10k Ohms load.
The oscillator can be specified to include various pulling range options, from ±5ppm to ±10ppm and also ±10ppm to ±15ppm. This enables the frequency to be adjusted by a fixed amount for various applications and also allows for the oscillator to be used remotely. The IQXT-210 is primarily designed for low power consumption applications such as Femtocells, Smart Wireless Devices, Fibre Optic Networking (PON), Microwave Satellite Communications, LTE/4G Base Stations, Backhaul Infrastructure, Packet Transport Network (PTN) Computer Networking, RF Modules, Wi-Fi plus Test & Measurement Equipment. Phase noise performance is -148dBC/Hz at 10kHz offset and short term stability is down at 5E-10/S.
All devices are RoHS compliant, reflow soldering compatible and supplied on tape and reel. Further information and the full data sheet is available at www.iqdfrequencyproducts.com.
