rev. 0.5 7/06 copyright ? 2006 by silicon laboratories si550 si550 v oltage -c ontrolled c rystal o scillator (vcxo) 10 mh z to 1.4 gh z features applications description the si550 vcxo utilizes silicon laboratories? advanced dspll ? circuitry to provide a low-jitter clock at high fre quencies. the si550 is available with any-rate output frequency from 10 to 945 mhz and selected frequencies to 1400 mhz. unlike traditional vcxo?s 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 provid es 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, including frequency, supply voltage, output format, tuning slope, and temperature stability. specific configurations are factory programmed at time of shipment, thereby eliminating long lead times associated with custom oscillators. functional block diagram available with any-rate output frequencies from 10 mhz to 945 mhz and selected frequencies to 1.4 ghz 3rd generation dspll ? with superior jitter performance 3x better frequency stability than saw based oscillators internal fixed crystal frequency ensures high reliability and low aging available cmos, lvpecl, lvds, & cml outputs 3.3, 2.5, and 1.8 v supply options industry-standard 5 x 7 mm package and pinout lead-free/rohs-compliant sonet / sdh xdsl 10 gbe lan / wan low-jitter clock generation optical modules clock and data recovery fixed frequency xo any-rate 10-1400 mhz dspll ? clock synthesis adc v dd clk+ clk? vc oe gnd ordering information: see page 7. pin assignments: see page 6.
