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.

See how Renesas' clock solutions can help meet system requirements and provide ease of use for configuration.
Hello, my name is Etienne Winkelmueller and I am product line manager for automotive timing at Renesas Electronics. I will talk to you today about clocks.
The challenge today as far as clocks are concerned is that due to the increase in data rates as well as system complexity, an entire new set of requirements are introduced, particularly higher frequency and lower jitter.
This demo shows how integrated clock generators can be used to create all the clock needed by a system. This particular example shows our Renesas R-Car SoC, but the example applies to any kind of electronic system.
Integrated clock generators feature many advantages. They can generate any frequency up to 350 megahertz with single ended or differential signaling and jitter level up to PCI Express Gen 4. They also have other functions such as spread spectrum or frequency reconfigurability.
The most popular feature of the device is the ease of use for configuration. Simply follow the link on the website and fill in your technical requirement in the table.
One of these clock generators can replace several crystal oscillators with lower footprints, more features, more flexibility and lower costs.
