The LMK04828-EP device is the industry’s highest performance clock conditioner with JESD204B support.

The 14 clock outputs from PLL2 can be configured to drive seven JESD204B converters or other logic devices using device and SYSREF clocks. SYSREF can be provided using both DC and AC coupling. Not limited to JESD204B applications, each of the 14 outputs can be individually configured as high-performance outputs for traditional clocking systems.

The high performance combined with features like the ability to trade off between power or performance, dual VCOs, dynamic digital delay, holdover, and glitchless analog delay make the LMK04828-EP ideal for providing flexible high-performance clocking trees.
