The is a high-performance Clock Jitter Attenuator with superior clock jitter cleaning, generation and distribution with advanced features to meet high performance timing application needs. The LMK04906 accepts 3 clock input ranging from 1kHz to 750MHz and generates 6 unique clock output frequencies ranging from 2.26MHz to 2.6GHz. It 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. The LMK04906 input clock frequency and clock multiplication ratio are programmable through a SPI interface.
