Description

The LMK0461x device family is the industry’s highest performance andlowest power jitter cleaner with JESD204B support. The 16 clock outputs can be configured to driveeight JESD204B converters or other logic devices using device and SYSREF clocks. The 17th outputcan be configured to provide a signal from PLL2 or a copy from the external VCXO.

Features like fully integrated PLL1 and PLL2 loop filters, a high numberof integrated LDOs, digital and analog delay, the flexibility to supply outputs with 3.3V, 2.5V and1.8V as well as the option to generate multiple SYSREF domains simultaneously makes the device easyto use.

Not limited to JESD204B applications each of the 17 outputs can beconfigured for traditional clocking systems.
