Automotive clock generator family gets built-in clock redundancy

26 January 2021

Silicon Labs has introduced SmartClock features to its family of AEC-Q100 qualified Si5332-AM clock generators.

The technology actively monitors reference clocks to detect potential faults and provides built-in clock redundancy. The technology also shares fault condition information with an external system microcontroller or system safety manager that can instruct the device to switch to a redundant backup source. This ensures operations will continue to operate safely.

Where health monitoring of only a single frequency is needed, Silicon Labs’ Si5118-AM SmartClock synthesizer can be implemented between the reference clock source and endpoint. These features are beneficial in applications such as automotive networking, advanced driver assistance systems (ADAS), automated driving and IVI/digital cockpit electronic designs.

Additionally, Silicon Labs has introduced a new standalone Si5118-AM SmartClock synthesizer, a new 120 output version of the Si5332-AM clock generator and a new 10 output version of the Si53350-AM buffer.
