Description
The Si5326 is a jitter-attenuating precision clock multiplier for applications requiring sub 1 ps jitter performance. The Si5326 accepts dual clock inputs ranging from 2 kHz to 710 MHz and generates two clock outputs ranging from 2 kHz to 945 MHz and select frequencies to 1.4 GHz. The two outputs are divided down separately from a common source. The device provides virtually any frequency translation combination across this operating range. The Si5326 input clock frequency and clock multiplication ratio are programmable through an I2C or SPI interface. The Si5326 is based on Silicon Laboratories' 3rd-generation DSPLL® technology, which provides any-rate frequency synthesis and jitter attenuation in a highly integrated PLL solution that eliminates the need for external VCXO and loop filter components. The DSPLL loop bandwidth is digitally programmable, providing jitter performance optimization at the application level. Operating from a single 1.8, 2.5, or 3.3 V supply, the Si5326 is ideal for providing clock multiplication and jitter attenuation in high performance timing applications.
