Renesas combines its experience in the automotive market with its expertise in timing to help fuel technology advances in electronics for automotive electronic systems. The Renesas VersaClock® automotive clock generators are PLL-based products that generate one or more clock signals for applications including, but not limited to, infotainment, dashboard, driver assist, Heads-Up Displays, and ADAS.
Fractional output divider technology allows generation of any combination of output frequencies, even those with no simple integer relationship. Clocks can be single-ended or differential, and support the latest in both PCI-Express and USB. One-time programmable (OTP) ROM is built-in, enabling customers to define a single device to power up as needed for multiple use cases.
The generation of dot clocks to drive LCD panels for infotainment or dashboard applications is an example use case where VersaClock devices are an appealing option as a replacement for crystal oscillators. Thanks to the highly configurable nature of VersaClock clock generators, a single PCB and BOM can be used regardless of the required dot clock frequency, alleviating the need to qualify different platforms when frequency needs change.
