The TRIXO-10-1000 ULN is an oven controlled pair of two high performance crystal oscillators: a 10 MHz time base providing phase-lock to a 100 MHz quarz oscillator with an integrated x10 multiplier. 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 module features very clean multiplication close to the theoretical 20logN rule as well as high subharmonics suppression. The oscillator provides more than +15 dBm of output power and draws less than 500 mA in the steady state from a +15V power supply. It comes in a compact aluminum milled form-factor and operates over the frequency range of 0…+50°C.
