HCMOS Oscillators Offer Low Stabilities
Performing at 2.5 V, Fox Electronics’ F540 Series HCMOS oscillators exhibit stabilities of 15 ppm (F547), 10 ppm (F549) and 8 ppm (F54S) with phase noise of -140 dBc/Hz at 10 kHz offset and a jitter period of 3 ps rms. The 5 mm × 3.2 mm RoHS-compliant components presents an input current of 7 mA, output current of 4 mA and output symmetry from 45% to 55% over a frequency range from 4 MHz to 54 MHz. The tape-and-reel packaged oscillators operate over a temperature range from -20°C to 70°C or from -40°C to 85°C, and have a maximum soldering temperature of 260°C at 10 seconds. The devices are suitable for test and measurement equipment, communication equipment and data transfer applications.
