Renesas Electronics Corporation has released the VersaClock 7, a programmable clock with an internal crystal oscillator. It is part of the VersaClock family of programmable clock generators that offer a combination of low power consumption, flexibility and performance. VersaClock 7 can simplify system design by replacing many discrete timing components and lower costs by reducing BOM and board space. VersaClock 7 enables users to configure frequencies, I/O levels and GPIO Pins. The programmable comes in a compact space-saving package. These features offer greater versatility in consumer, data communications, telecommunications, and networking applications.

Configurable clock generators with internal crystal oscillators are suitable for use in PCIe and networking applications in high-end computing, wired infrastructure and data center equipment. The clock generator provides a lot of flexibility, thus enabling designers to configure frequencies, Input/Output (I/O) levels, and General Purpose I/O (GPIO) pin functionality. VersaClock 7 combines low power consumption, cost-efficiency, and small package size. The high level of integration and the flexibility of programmability help manufacturers to reduce component counts, save board space and power. Additionally, using fewer components reduces the risk of supply chain issues disrupting production.

“Timing requirements can vary greatly between different applications and equipment, and will often change during a product design cycle,” said Zaher Baidas, Vice President of Renesas’ Timing Products Division. “VersaClock 7 gives our customers the flexibility to configure many design parameters while offering the best value available for their particular performance needs.”
