The 2038A from NEL Frequency Controls is a Phase-Locked Clean-up ULPN VCXO that operates at 10 MHz. It provides an output power of 10 dBm and has a rise/fall time of 4 ns. This VCXO has a G-sensitivity of ±0.5 ppb/G and a phase noise of -160 dBc/Hz @ 10 kHz offset. It requires a DC supply of 3.3/5 V and consumes 50 mW of power. It is available in a compact SMD package that measures 17.02 x 14.00 x 5.60 mm and is ideal for improving the phase noise of incoming signals, atomic clocks, GNSS-based clocks, test & measurement and COTS/dual-use applications.
