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.
