ProXO devices are available in multiple package options, including the industry’s smallest XO with sub-120 fs phase jitter performance, measuring just 2.5- x 2.0-mm. The high programmability of the devices gives designers the flexibility to select any frequency including those not readily available in traditional markets. Additionally, the devices have an input voltage range from 1.8-V to 3.3-V and offer four selectable output types (LVDS, CML, LVPECL and HSCL). All of these features are intended to save significant design time and get to market faster.
Additional features of the ProXO family include a self-contained resonator, which eliminates the needs for an external resonator and keeps the footprint small. The analog and digital steerable frequency control simplifies frequency adjustments to synchronize with data recovery clocks and smooths frequency switching to allow frequency tuning on the fly without resetting the system.
