The Si530/2/4 crystal oscillators utilize Silicon Laboratories advanced DSPLL® circuitry to provide a very low jitter clock for a wide range of output frequencies.
These oscillators provide an any-rate output from 10 to 945 MHz with selected frequencies up to 1400 MHz.
Unlike traditional high-frequency oscillators that require a different surface acoustic wave (SAW) resonator or high-frequency fundamental (HFF) crystal for each output frequency, the Si530 family uses DSPLL clock synthesis to generate all clock frequencies from one fixed, low-frequency crystal.
This new mixed-signal IC based approach allows the crystal resonator to be optimized for superior frequency accuracy, stability and reliability.
From a design perspective, the DSPLL clock synthesis IC provides superior supply noise rejection, simplifying the task of generating low jitter clocks in noisy environments often found in communications systems like SONET/SDH, 10GbE LAN/WAN and xDSL.
The Si530 operates at a fixed output frequency, while the output Si532 and Si534 support operation at two or four different frequencies, respectively.
For the dual frequency Si532 and the quad frequency Si534, the output frequency is determined via frequency select pins.
