Electronic Components & Devices

Miniature TCXOs consume 2 mA max.

Housed in 2.0 x 2.5 x 0.8 mm ceramic package, IQXT-260 Series employs analog ASIC for oscillator and high order temperature compensation circuit that provides smooth signal. Digitally compensated devices offer stabilities down to ±0.5 ppm over operating temperature range of -40 to +85°C with clipped sinewave output. Operating from 1.8–3.3 V, series is available in 3 versions: TCXO,...

GPS Frequency Reference offers atomic clock stability.

Designed to operate in conjunction with GPS or compass satellite signal, Model IQFR-100 delivers frequency accuracy of < ±1E-12 after 24 hr of stable satellite signal lock. In event of signal loss, unit maintains accuracy of better than 5E-11 until restoration of lock due to internal reference oscillator. Housed in 1U rack mountable cabinet, IQFR-100 provides two 10 MHz square wave outputs,...

Tight Stability Clock Oscillators come in two package sizes.

Respectively supplied in 2.5 x 2.0 mm and 3.2 x 2.5 mm ceramic packages, IQXO-445 series and IQXO-430 series deliver frequency stabilities as low as ±10 ppm over full -40 to +85°C range. Both series are available over 4–54 MHz range, consume 3.1 mA at 40 MHz, and offer phase noise performance of -145 dBc/Hz at 10 kHz offset. Output is CMOS-compatible with up to 15 pF load, and both...
