LMK00105SQE/NOPB Product Details

The LMK00105SQE/NOPB is a high-performance, low-noise LVCMOS fanout buffer which can distributefive ultra-low jitter clocks from a differential, single-ended, or crystal input. The LMK00105supports synchronous output enable for glitch-free operation. The ultra low-skew, low-jitter, andhigh PSRR make this buffer ideally suited for various networking, telecom, server and storage areanetworking, 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 LMK00105SQE/NOPB can be easily configured through pin programming.
