The DOCXO3628BM-10MHz-312 from Dynamic Engineers is a 10 MHz Oven-Controlled Crystal Oscillator (OCXO). It produces a CMOS output waveform with a frequency stability (vs operating temperature) of ±0.5 ppb and has an SSB phase noise of -155 dBc/Hz (at 10 kHz offset). This OCXO is designed for applications where exceptional frequency stability and timing are required. It has an operating temperature range of -10°C to +70°C and has excellent temperature performance and short-term stability. This oscillator requires a DC supply of 5 V and consumes less than 2.5 W of power. It is available in a package that measures 36 x 27 x 18 mm and is ideal for instruments, data communication, test and measurement, GPS and telecom applications.
