Description
AI
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 LMK04906 accepts 3 clock inputs ranging from 1 kHz to 500 MHz and generates 6 unique clock output frequencies ranging from 284 kHz to 2.6 GHz. The LMK04906 can also buffer a crystal or VCXO to generate a 7thunique clock frequency.
The device provides virtually all frequency translation combinations 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.
