GPS Frequency Reference offers atomic clock stability.

January 27, 2015

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, 2 square wave outputs at 2.048 MHz, and two 1 PPS impulse outputs with holdover specification of ≤1.5 µs.

Miniature VCXOs range from 40-170 MHz.

November 24, 2014

Packaged in 3.2 x 2.5 mm 6-pad ceramic package with hermetically sealed metal lid to reduce EMI radiation, Model IQXV-80 offers LVPECL output while Model IQXV-81 offers LVDS. Both operate from 3.3 V power source and are available with stabilities of ±25 ppm or ±50 ppm over operating temperature range of -40 to 85°C. In either case, frequency can be adjusted externally by application of control voltage (1.65 V ±1.5 V) which can pull output frequency by minimum of ±80 ppm. Read More

Oven Controlled Crystal Oscillator incorporates GPS receiver.

November 4, 2014

Housed in 14-pin 60 mm² package, IQCM-110 Series incorporates internal GPS receiver with 1 PPS output. When coupled to external aerial via SMA connector, in event of loss of GPS signal, 10 MHz OCXO will switch-in with holdover capability of 1.5 µs for 24-hour period, maintaining lock until restoration of reference signal. Internal alarm indicates lock failure and subsequent restoration of signal. Operating from -20 to +75°C with 5 V power supply, oscillator delivers standard HCMOS output. Read More

Shock-Resistant Oscillator performs in high-temperatures.

September 18, 2014

Supplied in TO-39 package, SQXO-2ATHG can withstand shock levels up to 8,000 g for 0.5 msec, ½ sine, for use in such applications as underground boring tools, down hole instrumentation, and avionics. Frequencies are available from 32.768 kHz to 50 MHz, and products can be specified to operate from 3.3 or 5 V supply. Providing CMOS output and start up time of under 5 msec, fully RoHS-compliant oscillators consume as little as 3.0 mA and come in variants available for operation up to 200°C. Read More

Tight Stability Clock Oscillators come in two package sizes.

July 22, 2014

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 models include tri-state capability. Available supply voltages are 2.5, 3.0, or 3.3 V. Read More

OCXO delivers ±0.2 ppb frequency stability.

June 13, 2014

Covering 10–40 MHz range, IQOV-164 series comes in 5-pin euro package measuring 36 x 27 x 13.5 mm and delivers ±0.2 ppb frequency stability from -20 to +70°C or ±0.5 ppb from -30 to +75°C. Frequencies are available up to 100 MHz with stability of ±10 ppb from -30 to +75°C. Consuming 7.0 W max during 3 min warm up, series operates from 3.3 V supply and offers output that can be specified as HCMOS, 15 pF load, or Sinewave into 50 Ω load. Phase noise is typ -158 dBc/Hz at 100 kHz offset. Read More

TCVCXO delivers ±0.14 ppm stability in 5 x 3.2 mm package.

June 3, 2014

Powered from 3.3 V supply, IQXT-210 Series offers frequency stabilities down to ±0.14 ppm over industrial temperature range of -40 to 85°C. Units typically draw 12 mA, dependent upon frequency, which can be specified between 10–50 MHz. Output can be specified as either HCMOS, 15 pF load, or Clipped Sine, into 10 kΩ load. In addition, oscillator can be specified to include various pulling range options, from ±5 to ±10 ppm and ±10 to ±15 ppm. Phase noise is -148 dBC/Hz at 10 kHz offset. Read More

Miniature OCXO delivers ±5 ppb stability.

May 2, 2014

Supplied in 14 x 9.0 x 6.5 mm package, IQOV-162 series is available in 10–100 MHz frequency range and provides frequency stability down to ±5 ppb from -40 to +85°C. OCXO operates from 3.3 V supply, consumes 600 mA during warm up, and takes <5 min to be within <100 ppb of final specification and 300 mA max at steady state at 25°C. Output can be specified as HCMOS, 15 pF load, or Sinewave into 50 Ω load, and phase noise performance is better than -150 dBc/Hz @ 1 kHz offset. Read More
