TCVCXO achieves ±0.14ppm stability in a 5 x 3.2 mm outline

May 27, 2014 // By Graham Prophet
IQD’s IQXT-210 series TCVCXO offers frequency stabilities down to ±0.14ppm over the full industrial temperature range of -40 to 85C. This is approaching OCXO performance levels, whilst being packaged in a miniature 8-pad 5 x 3.2 mm package.

Powered from a 3.3V supply the IQXT-210 has a typical current draw of only 12 mA dependent upon the frequency, which can be specified between 10 MHz to 50 MHz. 11 standard frequencies are initially offered, including 12.8 MHz, 19.2 MHz and 26.0 MHz.

Output can be specified as either HCMOS, 15 pF load or Clipped Sine, into 10 kOhms load. The oscillator can be specified to include various pulling range options, from ±5 ppm to ±10 ppm and also ±10 ppm to ±15 ppm. 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 -148 dBC/Hz at 10 kHz offset and short term stability is down at 5E-10/sec.
