Clock & Timing Solutions for Wired Applications

Highly-Flexible Clocking ICs Simplify Wired Communications System Design

NEW! LMK04906 Ultra Low Noise Clock Jitter Cleaner/Multiplier with 6 Programmable Outputs



The LMK04906 is the most flexible and highly integrated clock jitter cleaner/multiplier, delivering the industry's lowest jitter and phase noise: 100 fs RMS jitter from 12 kHz to 20 MHz and low noise floor of -160 dBc/Hz at 156.25 MHz output frequency.

Key features and benefits

  • Flexible, high performance, programmable outputs offered in LVDS, LVPECL and LVCMOS formats simplifies timing design
  • Integrated features such as holdover, input switching, analog/digital delay, and odd/even dividers increases functionality and reduced BOM cost and need for external components
  • Industry's lowest jitter enables better signal integrity in high speed data communication links such as 10GbE, FC, FCoE, and SAS/SATA

NEW! CDCM6208 Ultra Low Power, Low Jitter Clock Generator with Fractional Dividers



The CDCM6208 combines supply voltage flexibility, low power, very low phase noise, and the flexibility of frequency planning using fractional divider is unmatched in the industry.

Key features and benefits

  • 265 fs RMS jitter
  • Low power: <500 mW typ
  • Flexible frequency planning: four fractional output dividers that allow for a total of five unrelated and one related frequency (e.g. USB, PCIe, DDR memory, CPU, CPRI, OBSAI, SonetSDH, SyncE, GbE).
  • Flexible supply voltage: all supplies support 1.8 to 3.3 V independently

LMK03806 Ultra Low Jitter Clock Generator with 14 Programmable Outputs



The LMK03806 clock generator dramatically simplifies timing architectures by replacing fixed-frequency clock generators, discrete level translators, fanout buffers, XOs, VCXOs, and VCSOs with a single device. With its higher integration and flexibility, the LMK03806 can reduce required board space by up to 80% and BOM cost by up to 50%.

Key features and benefits

  • High-frequency voltage-controlled oscillator (VCO) and programmable output dividers simplify timing design by simultaneously generating a wide array of common frequencies
  • Ultra-low jitter: Sub-50 fs RMS jitter at 312.5MHz output frequency improves bit error rate and carrier-to-noise ratio performance
  • Programmable LVDS, LVPECL and LVCMOS: Each output clock is independently configurable, eliminating the need for level translators and fanout buffers
  • Crystal interface: Allows the use of a low-cost crystal for simultaneously generating multiple clocks
