Clock & timing

Improve overall system performance with our clock jitter cleaners

Industry’s lowest power and lowest jitter JESD204B-compliant jitter cleaners

Industry's best performance

These devices feature ultra-low jitter of 65 fs typ 12k-20M at 122.88 MHz and 50 fs typ 12k-20M at 1966.08 MHz and ultra-low in-band phase noise through leading BiCMOS technology.

JESD204B made easy

The industry’s first JESD204B jitter cleaner family, LMK0482x, supports JESD204B and non-JESD204B applications with a single device. Full SYSREF support reduces SoC complexity and cost. Multiple SYSREF frequencies from one device.

PLLATINUM dual loop PLL

The PLLATINUM dual phase-locked loop (PLL) concept reduces cost and improves performance. The innovative semi-digital PLL technique offers the best performance while integrating PLL loop filter components and supporting <5 Hz of loop bandwidth.
