Wireless Infrastructure Applications 

Silicon Labs offers a comprehensive clock and oscillator portfolio for wireless infrastructure applications. These devices eliminate the need for discrete VCXO and loop filter components, simplifying design, and minimizing overall solution costs. Silicon Labs’ clock products are highly frequency flexible, generating any combination of frequencies from any input frequency with unparalleled performance and enabling “clock-tree-on-a-chip” BOM consolidation. Silicon Labs also offers ultra-low jitter programmable oscillators customizable to any frequency, with samples available in less than two weeks. Silicon Labs’ PCI Express timing products provide fully compliant PCIe Gen 1/2/3 clock generation and distribution.
