Renesas leverages its experience in timing as well as in automotive to create next-generation clock devices. The Renesas VersaClock® automotive clock generators are PLL-based products that generate one or more clock signals for applications such as infotainment, dashboard, driver assist, ADAS, and more.

Fractional output divider technology allows generating any set of output frequencies unrelated to each other. Clocks can be either single-ended or differential, with sufficient performance for PCI-Express Gen3 or USB 3.0. Built-in one-time programmable (OTP) ROM enables the use of one device with different configurations over many platforms. A typical use case where VersaClock devices excel is in the generation of dot clocks to drive LCD panels for infotainment or dashboard applications, replacing 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 and alleviates the need to qualify different platforms when frequency needs change.

Integrated Clock Generator for Automotive

See how Renesas' clock solutions can help meet system requirements and provide ease of use for configuration.

Video Transcript

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.
