IQD Frequency Products' IQMT-100 series MCXO offers customers OCXO performance in a standard clock oscillator sized package. The design enables frequency stability of ±50 ppb over the full industrial operating temperature range of -40°C to +85°C while maintaining an excellent typical short-term stability of 2E-10/s. The IQMT-100 is housed in an industry standard sized ceramic package measuring just 7.0 mm x 5.0 mm with both 8- and 10-pad options available over a frequency range of 10 MHz to 50 MHz. Output can be either clipped sine or HCMOS with 15 pF load along with 3.0 V, 3.3 V, and 5.0 V supply voltages. A voltage control option is available to control the frequency drift to compensate for crystal aging and varying circuit conditions with choices of either ±5 ppm to ±10 ppm or ±10 ppm to ±15 ppm. Aging per day is 20 ppb and standard aging over one year is 1 ppm. Typical phase noise performance is -145 dBc/Hz at 100 kHz.

The IQMT-100 is primarily designed to be used in applications such as femto, pico, and macrocell base stations, digital switching, GPS/GNSS, microwave backhaul, digital video broadcast, satellite upconverters, and environmental monitoring equipment. The IQMT lends itself to portable use since its current draw is 10 mA and it is ideal for use where an OCXO cannot be used due to size and power consumption restrictions and where tight frequency stability is required which a TCXO/VCTCXO cannot achieve.
