Renesas VersaClock Programmable Clock Generators

The Renesas VersaClock® family of programmable clock generators combines low power consumption, flexibility, and high performance to dramatically simplify system design by replacing multiple discrete timing components, while reducing bill of materials (BOM) and board space, effectively lowering overall system cost.

The VersaClock family of products offers excellent technical features, supports a wide operating voltage range of 1.8V to 3.3V, and provides a wide selection of output types, including differential outputs (LVPECL/HCSL/LVDS/LP-HCSL) and LVCMOS outputs. With up to three PLLs (phase-locked loops) and multiple fractional frequency dividers integrated internally, the VersaClock is capable of accurately generating clock signals at virtually any frequency, meeting a wide range of system requirements from replacing simple oscillators to high-precision communication applications such as PCIe® Gen 1/2/3/4/5/6. Particularly noteworthy is that the VersaClock 6 series has RMS phase jitter of less than 500 femtoseconds (fsec), the best performance in the VersaClock family, while maintaining extremely low operating power consumption, with a core current consumption of only 30mA, much lower than the 213mA of comparable products.

Renesas Crystal Oscillator Products

The Renesas family of programmable crystal oscillators is well known in the industry for its extreme design flexibility and superior performance. Unlike traditional fixed-frequency oscillators, Renesas XO products allow users to customise the frequency and other key parameters to meet specific application requirements, significantly reducing lead times and minimising non-recurring engineering (NRE) effort.

On the technical parameter side, the Renesas crystal oscillator family offers industry-leading low jitter clock sources with typical RMS phase jitter as low as 120 fs (femtoseconds), a metric that is critical for high-speed serial communications and RF systems. The family supports programmable frequencies up to 2.1GHz, covering the clocking needs of most modern electronic systems. In addition, Renesas XO products are available in a variety of performance, output type, stability, input voltage, package, pin configuration and temperature ratings, allowing users to select the most appropriate configuration for their specific application scenario. For example, an industrial grade temperature range of -40°C to +85°C may be required for industrial automation equipment, while automotive electronics applications require an automotive grade device that meets AEC-Q100 standards.

Renesas Jitter Attenuator Technology

Renesas jitter attenuator products are designed to address the challenge of phase noise and jitter in clock signals that are critical to the performance of high-speed digital systems and communications equipment. Renesas jitter attenuators utilize low-jitter external references and control circuits to efficiently remove unwanted noise from one or more input clock signals, dramatically improving signal integrity and providing reliable signal integrity for high-speed data transmission and precision measurements. data transmission and precision measurements.

The core technical feature of Renesas jitter attenuators is their innovative architectural design. These products use VCXOs (voltage controlled crystal oscillators) or simple crystals as the reference source, and patented technology allows the use of fixed-frequency crystals in place of hard-to-obtain pullable crystals in traditional designs, greatly simplifying material sourcing and supply chain management. What's more, Renesas jitter attenuators incorporate a frequency conversion function that allows the output frequency to be different from the input frequency, and the ratio of the two can be integer or non-integer, depending on the device model selected. Some high-end models even support multiple frequency ratios, enabling the generation of multiple independent frequencies to meet the needs of complex systems with multiple clock domains.
