Addresses the growing need for clock monitoring and fault detection to check the health of system clocks, thus improving design operation
To facilitate monitoring of reference clocks to detect potential faults and provide built-in clock redundancy, new SmartClock features have been introduced to the AEC-Q100 qualified Si5332-AM clock generators
On detection of a fault condition, SmartClock shares this information with an external system microcontroller or system safety manager, which instructs the Si5332-AM to switch to a redundant backup source, ensuring continued safe system operation. In health monitoring applications requiring single frequency, the new Si5118-AM SmartClock synthesiser can be implemented between the reference clock source and endpoint.
These innovative new features help address the increasingly complex timing challenges faced in automotive networking, advanced driver assistance systems, automated driving and IVI/digital cockpit electronic designs.
“Automotive electronics designs have traditionally relied on quartz crystals and oscillators, which are susceptible to failure over their operating lifetime. As timing requirements become more complex within automotive applications, the number of precision clocks needed also continues to increase,” said James Wilson, General Manager of timing products at Silicon Labs. “Our SmartClock technology provides system designers with new tools to actively monitor the health and reliability of their system clocks, improving the resiliency and operation of each design.”
The following new products and features are now available from Silicon Labs:
⦁ SmartClock health monitoring, fault detection and local backup reference with new, customisable features in the Si5332-AM clock generator family. These features can be enabled using Silicon Labs ClockBuilder Pro configuration software.
⦁ New standalone Si5118-AM SmartClock Synthesiser
⦁ New 12-output version of the Si5332-AM clock generator
⦁ New 10-output version of the Si53350-AM buffer
