The TCXO7500BT-50MHz-A-V from Dynamic Engineers is a High Stability TCXO that operates at 50 MHz. It has a phase noise of -153 dBc/Hz @100 kHz offset and a frequency stability of up to ±0.28 ppm over a temperature range from -40 to 85 degrees Celcius. This TCXO provides an LV (CMOS) output while operating on a supply voltage of 3.3 V. It is available in a surface-mount miniature package that measures 7 x 5 x 1.8 mm and is ideal for use in UHF synthesizers, SATCOM systems, and portable microwave applications.
