Clock & Timing | National Semiconductor – LMX PLLatinum PLLs & PLL+VCO, LMK Clock Jitter Cleaners / Conditioners, and Low-Jitter Clock Distribution

PLL-Based Devices

Single Output
LMX PLL Frequency Synthesizers National's PLLatinum® Family Portfolio includes the industry's lowest noise monolithic PLL ICs and frequency synthesizers. The LMX2541 world's lowest PLL with bypass-able integrated VCO, providing less than 2 mrad RMS noise at 2.1 GHz and 3.5 mrad at 3.5 GHz.
Multiple Output
LMK Clock Generators, Cleaners, and Distribution National's LMK Family of Precision Clock Conditioners improves system performance and accuracy. The new LMK03806 highly integrated clock generator with the industry's best jitter performance delivers 14 programmable outputs from a low-cost crystal, XO, or reference clock.
