SILICON LABS 591QB156M250DGR

Available CMOS, LVPECL, LVDS, and CML outputs. 3.3, 2.5, and 1.8 V supply options. Industry Standard 5x7 and 3.2x5 mm packages. Pb-free/RoHS-compliant. –40 to +85 ℃ operating temperature range. The Si590/591 XO utilizes Silicon Laboratories’ advanced DSPLL circuitry to provide a low jitter clock at high frequencies. The Si590/591 supports any frequency from 10 to 810 MHz. Unlike a traditional XO, where a unique crystal is required for each output frequency, the Si590/591 uses one fixed crystal to provide a wide range of output frequencies. This IC based approach allows the crystal resonator to provide exceptional frequency stability and reliability. In addition, DSPLL clock synthesis provides superior supply noise rejection, simplifying the task of generating low jitter clocks in noisy environments typically found in communication systems. The Si590/591 IC based XO is factory configurable for a wide variety of user specifications including frequency, supply voltage, output format, and stability. Specific configurations are factory programmed at time of shipment, thereby eliminating long lead times associated with custom oscillators.
