The LMK00105 is a high-performance, low-noise LVCMOS fanout buffer which can distribute five ultra-low jitter clocks from a differential, single-ended, or crystal input. The LMK00105 supports synchronous output enable for glitch-free operation. The ultra low-skew, low-jitter, and high PSRR make this buffer ideally suited for various networking, telecom, server and storage area networking, RRU LO reference distribution, medical and test equipment applications.

The core voltage can be set to 2.5 or 3.3 V, while the output voltage can be set to 1.5, 1.8, 2.5 or 3.3 V. The LMK00105 can be easily configured through pin programming.
