Fox Electronics expanded its HCMOS oscillator line with the FOX251 Ultra Miniature series TCXO. Available in a 2.5 mm x 2.0 mm package, the ultra miniature series can be used as general tight tolerance clocks in digital systems that can take advantage of the small size and HCMOS output. These SMT HCMOS TCXOs feature a frequency range of 4 MHz to 54 MHz with stabilities as tight as ±2.5 ppm over the -30°C to +85°C operating temperature range, ±0.2 ppm over the supply voltage change and ±0.2 ppm over the load change. Storage temperature is -40°C to +125°C. Frequency tolerance is ±1.5 ppm at 25°C. The RoHS-compliant oscillators offer an input current of 3.1 mA to 7.0 mA depending upon the model and frequency. Standby current is 10 µA. Output load is 15 pF. Typical phase noise at a 10 kHz offset is -145 dBc/Hz. The new TCXOs feature a gold termination finish. Pricing is $1.79 in quantities of 10,000.
