Clocks & Timing

Renesas jitter attenuators make use of a low-jitter external reference and control circuitry to remove unwanted noise from one or more input clock signals. Different members of this category of products make use of VCXOs or simple crystals as this reference. Innovative techniques allow the use of fixed-frequency crystals rather than hard-to-find pullable crystal devices. In addition, the jitter attenuator products also include a frequency translation stage that allows the output frequency or frequencies to be different than the input frequency. This input-output frequency may be an integer or non-integer ratio depending on the device selected. Several devices within the family will allow multiple such ratios to be supported, resulting in multiple independent frequencies or even non-integer relationships between output frequencies.

The integration of a jitter attenuator and frequency translator simplifies the circuit and minimizes the bill-of-materials (BOM). Renesas' rich portfolio of jitter attenuators and frequency translators come in varying levels of performance, power, and programmability to address the needs of virtually any application. Renesas jitter attenuators support various single-ended and differential signaling levels such as LVCMOS, LVPECL, LVDS, HCSL, HSTL, or SSTL.

Applications and Standards

 

What is a Jitter Cleaner?

A jitter cleaner (aka jitter attenuator) is a device which is used to reduce the magnitude of noise (jitter) on a given timing signal. Jitter can be described as the undesired deviation from an ideal periodic timing signal. Jitter is commonly observed in characteristics such as the phase, or amplitude of successive pulses, and/or changes in frequency over a given time frame. High levels of jitter often result from long traces, cabling, and noisy system environments. Excessive levels of Jitter cause undesired system behavior in high-performance applications. Renesas jitter cleaners (jitter attenuators) rely on stable reference sources and innovative control circuitry to lock on to the phase and average frequency of a noisy clock signal and then output a high-quality (low jitter) signal to be sourced to ‘downstream’ devices within the clock network.

    Parametric Table tips

    Tips for Using This Parametric Table:

    • Hide Filters button in header: Collapse or expands filters
    • Column sort buttons in header: Sort Column alphabetically / numerically descending or ascending
    • Reset button in header: Reset all filters to the page default
    • Full Screen button in header: Expand the table to full screen view (user must close out of full screen before they can interact with rest of page)
    • Export button in header: Export the filtered results of the table to an Excel document
    • Filter parts search bar in header: Type to filter table results by part number
    • Hide column button in column headers: Select to hide columns in table
    • AND / OR toggle switches in header: Toggles the logic of this particular filter to be “AND” or “OR” logic for filtering results
    • Multiselect checkboxes at beginning of each row in table: Select these checkboxes to compare products against each other
    • Document icon next to product name in row: View the featured document for this product

    ClockMatrix™2 System Synchronizer Overview

    The ClockMatrix™ 2 family of devices are high-performance, precision timing solutions designed to simplify clock designs for applications with up to 800Gbps interface speeds. This second-generation family delivers improved performance with phase jitter as low as 88fs RMS. The highly integrated devices serve as full-function IEEE 1588 synchronization clocks and ultra-low jitter reference clocks for synchronous Ethernet PHYs with data rates up to 112Gbps PAM-4, reducing design complexity and bill of materials (BOM).
