Application Videos

The TRIXO-10-100 ULN is an oven controlled pair of two high performance crystal oscillators: a 100 MHz oscillator locked to a 10 MHz quartz time base. While the 100 MHz oscillator provides a very low noise floor, the 10 MHz oscillator determines the optimum phase noise profile at close-in offsets and guarantees excellent frequency stability. The oscillator provides more than +13 dBm of output power and draws 800 mA in the steady state from a +12V power supply. It comes in a compact aluminum milled form factor and operates over the frequency range of 0…+50°C.
