Description

The LMK00101 is a high performance, low noise LVCMOS fanout buffer which can distribute 10 ultra-low jitter clocks from a differential, single ended, or crystal input. The LMK00101 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 LMK00101 can be easily configured through pin programming.
