OCXOs boast improved phase noise performance
A series of ultra-miniature Oven Controlled crystal Oscillators (OCXOs) from IQD Frequency Products are available at Richardson RFPD with full design support. The IQOV-162 Series of OCXOs is offered in 14.4x9.5x6.5mm SMD metal can packages. Standard frequencies include 10.0, 12.8, 19.2, 20.0 and 38.88MHz, with either an HCMOS or sinewave output.
The OCXOs also feature phase noise performance better than -150dBc/Hz (at 1kHz) and extremely good ageing performance of +/-500ppb (max) per year.
Operating from a 3.3V supply voltage, the OCXOs feature a warm-up current draw of 560mA (max) and a steady state of 250mA (max) at 25°C. They require less than five minutes to be within 100 ppb of the final frequency.
Stability of +/-20ppb over an operating temperature range of -40 to +85°C makes the IQOV-162 Series suitable for base station, femtocell, satellite communication, and SATA applications.
