Si550

Si550 REVISION D VOLTAGE-CONTROLLED CRYSTAL OSCILLATOR (VCXO) 10 MHZ TO 1.4 GHZ Features  Available with any frequency from  Internal fixed crystal frequency 10 to 945 MHz and select ensures high reliability and low frequencies to 1.4 GHz aging  3rd generation DSPLL® with  Available CMOS, LVPECL, superior jitter performance (0.5 ps) LVDS, and CML outputs  3x better temperature stability than  3.3, 2.5, and 1.8 V supply options SAW-based oscillators  Industry-standard 5 x 7 mm  Excellent PSRR performance package and pinout  Pb-free/RoHS-compliant Applications  SONET/SDH  xDSL  10 GbE LAN/WAN  Low-jitter clock generation  Optical modules  Clock and data recovery Description The Si550 VCXO utilizes Skyworks Solutions’ advanced DSPLL® circuitry to provide a low-jitter clock at high frequencies. The Si550 supports any frequency from 10 to 945 MHz and select frequencies to 1417 MHz. Unlike traditional VCXOs, where a different crystal is required for each output frequency, the Si550 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 Si550 IC-based VCXO is factory-configurable for a wide variety of user specifications, includi...
