Silego Technology Intros Low Power EMI Reduction Clock Generators

Silego Technology, a provider of timing generators, has unveiled a complete line of low power, low jitter 1x, 2x, and 4x frequency multiplier Electro-Magnetic Interference (EMI) reduction spread spectrum clock generators (SSCG). By spreading clock energy by a fixed amount, these SSCGs reduce EMI radiation.

 

Featuring low power consumption of less than 20mA, the SLG431x is a 1x, 2x, and 4x frequency multiplication SSCG family. It also provides low cycle-to-cycle jitter in the sub 100ps range with an input frequency range of 4MHz to 32MHz. The SLG4318 is equipped with both a spread spectrum output and a non-spread spectrum reference output and is a 1x EMI reduction -1.25% SSCG with a power down mode. Also, the SLG4318 is ideal for video graphics and other applications requiring -1.25% down spread as the input frequency range of the device is from 20MHz to 40MHz.

 

SSCGs design faces many challenges such as maintaining a symmetrical spread profile and generating less jitter and consuming less power. When benchmarked against competitive products, SLG431x and SLG4318 demonstrate best in class performance.

 

SSCGs offer many benefits such as eliminating the need for expensive shielding, lowering BOM costs, and reducing time to market. SSCGs are used in consumer applications such as HDTVs, set-top boxes, and printers, computing applications such as servers, and PCs and high-speed communication routers, switches.

 

Located in Santa Clara, California, Silego specializes in silicon timing solutions. The company has two design centers located in Santa Clara, California, and in Seoul, Korea and has a sales office in Taipei. Catering to the computation, communication, consumer, and DIMM markets, Silego offers a complete line of timing products. Silego has shipped more then 50M units in 2007 to numerous top-tier OEMs and ODMs.

 

“We are pleased to offer both the SLG431x and SLG4318. The SLG431x and SLG4318 are SSCGs that offers lowest power consumption and the lowest jitter in the industry. These products were built from the ground up using the latest fabrication process technology,” says Herbe Chun, Sr. Product Marketing Manager, Silego Semiconductor.
