RF Crystal Oscillator Suppresses Jitter, Phase Noise

Sonet, SDH, ATM, and WAN applications are the main targets for the RFX300 series (rfXO) of high-performance RF crystal oscillators. The devices feature just 3-ps RMS jitter, 0.5-ps phase jitter, and 30-ps cycle-to-cycle jitter. Frequency stability is ±20 to ±100 ppm and covers from 600 MHz to 1.25 GHz. Output symmetry is 45% to 55% V p-p over the frequency range. Standard operating-temperature ranges from −20°C to 85°C. The unit comes in a standard package measuring 7.5 by 5.0 by 1.5 mm. It has complementary LV-PECL outputs in 3.3- and 2.5-V versions. A 622.8-MHz unit starts at $32 each in 1000-unit lots, with delivery in 10 to 12 weeks.
