LMK04906 datasheet



The LMK04906 is the industry’s highest performance clock jitter attenuator with superior clock jitter cleaning, generation, and distribution with advanced features to meet high performance timing application needs.

The device accepts 3 clock input ranging from 1 kHz to 750 MHz and generates 6 unique clock output frequencies ranging from 2.26 MHz to 2.6 GHz. The LMK04906 can also buffer a crystal or VCXO to generate a 7th unique clock frequency.

The device provides virtually all frequency translation combination required for SONET, Ethernet, Fibre Channel and multi-mode Wireless Base Stations.
