Clocks Clamp Jitter At <100 fs

Clocks Clamp Jitter At <100 fs
Silicon Laboratories Inc.

Launched as the industry’s most frequency-flexible clocks with the lowest jitter, the next-gen Si534x clock-tree-on-a-chip timing devices combine clock synthesis and jitter attenuation functionality to reduce the cost and complexity of a variety of applications. These include optical networking, wireless infrastructure, broadband access/aggregation, Carrier Ethernet, test and measurement, and enterprise/data center equipment including edge routers, switches, storage and servers. The Si5347/46/45/44/42 jitter attenuators and Si5341/40 clock generators provide an I2C-configurable platform with jitter performance less than 100 fsRMS. By combining up to four independent jitter-attenuating PLLs and up to five ultra-low-jitter MultiSynth fractional synthesizers, the family is capable of generating up to 10 outputs with any combination of frequencies from 100 Hz to 800 MHz in a wide range of user-selectable output formats, i.e., LVPECL, LVDS, CML, HCSL and LVCMOS. Factory pre-programmed samples of the Si534x clock generators and jitter attenuators are available in QFN packages as small as 7 mm x 7 mm. Si5341/40 clock generator pricing ranges from $4.75 to $10.60, and Si534x jitter attenuator pricing ranges from $6 to $29 each/10,000. For more information, visit
