RFMW announces design and sales support for a high reliability, Microprocessor Controlled Crystal Oscillator (MCXO) from Microsemi. With low power consumption and excellent phase noise and Allan deviation, the MX-503 series oscillators offer +/- 5 ppb frequency stability in a 24 hour period at constant temperature. Operating temperature range is -40 to 85 degrees Celsius, making the device suitable for 4G and 5G implementations. Frequencies are available between 8 and 50 MHz with standard frequencies of 10, 12.8, 20, 16.384, 19.2, 20, and 22.1184 MHz. For example, the MX-5030-EAE-3080-10M0000000 provides a 10 MHz output frequency with +/- 30 ppb stability with a HCMOS output operating on a 3.3 V supply. Package size is 9.5 x 14.4 x mm.
