Frequency Products
Growing timing IC portfolio
Real
Silicon Laboratories has expanded its timing IC portfolio, adding over 100 clock generation and clock distribution products designed for cost-sensitive, high-volume consumer, enterprise, communications and embedded applications.
General purpose low voltage CMOS clock generators are
programmable clocks offering 1-11 outputs and frequencies up to 200MHz. They are used in digital cameras, printers, graphics cards, set-top boxes, HDTVs and home gateways.
PCI Express (PCIe) Generation 1/2/3 clock generators are
customizable and fixed-function clocks with programmable output frequencies up to 400MHz. They are optimised for the PCIe interconnect standard used in consumer, server, storage, IP gateway and industrial systems.
X86 clock generators for embedded systems are said to offer
the lowest power consumption for industry-leading x86 platforms and are widely used in applications such as storage, blade servers, STBs, home/industrial automation andmedical equipment.
Clock distribution products include: zero-delay buffers and
LVCMOS fanout buffers used in servers, routers and switches; temperature-controlled XO (TCXO) fanout buffers for smart phones, tablets and other handheld products; and PCIe buffers for a range of PCIe applications.
