Silicon Labs introduces broad portfolio of automotive grade timing solutions

Silicon Labs has launched the industry’s broadest portfolio of automotive grade timing solutions designed to meet the demanding clocking needs of in-vehicle systems. The new AEC-Q100-qualified timing devices include Si5332 any-frequency programmable clock generators, Si5225x PCIe Gen1/2/3/4/5 clocks, Si5325x PCIe buffers and Si5335x fanout clock buffers. These timing devices help automotive OEMs and Tier 1 suppliers simplify clock tree design, reduce system points of failure, increase system reliability and optimize the performance of high-speed serial data transfer. The devices target a wide range of automotive applications including camera sub-systems, radar and LIDAR sensors, ADAS, autonomous driving control units, driver monitoring cameras, infotainment systems, Ethernet switches, and GPS and 5G connectivity.

The Si5332 clock leverages Silicon Labs’ proven MultiSynth technology to provide any-frequency, any-output clock synthesis with more than 60 percent lower jitter than competing automotive clock solutions. Supporting up to eight clock outputs, selectable signal formats per output clock (LVDS, LVPECL, HCSL, LVCMOS) and independent 1.8-3.3V VDDO, the Si5332 clock easily interfaces to a broad range of FPGAs, ASICs, Ethernet switches/PHYs, processors, GPUs, SoCs, and PCIe Gen1/2/3/4/5 and NVLink SerDes. Clock synthesis, clock distribution and format/level translation are consolidated on-chip, enabling optimized single-IC clock tree solutions for automotive designs. 

The Si5332 clock generators and Si5335x clock buffers are configurable and customizable using Silicon Labs’ flexible ClockBuilder Pro software, enabling developers to create optimized solutions that exactly match specific clock tree requirements, with samples shipping in less than two weeks.
