Si537x 4-PLL Jitter Attenuating Clock ICs

Skyworks Solutions Inc. Si537x 4-PLL Jitter Attenuating Clocks are the first single-chip timing ICs to integrate four independent, high-performance phase-locked loops (PLLs), providing twice the PLL integration and 40 percent lower jitter than competing solutions. Skyworks Si537x clock ICs with DSPLL® technology address the complex timing requirements of high-speed optical transport network (OTN) applications. The Si5374 has eight input clocks and eight output clocks, while the Si5375 offers four input clocks and four output clocks for applications requiring fewer clocks. With its quad-DSPLL configuration, a single Si5374 clock can generate different frequencies simultaneously, enabling the design to support SONET/SDH, 1/10/100G Ethernet, 1/2/4/8/10G Fibre Channel, 3G/HD SDI video, and other protocols simultaneously in the same device.
