General Description

The LTC®6952 is a high performance, ultralow jitter, JESD204B/C clock generation and distribution IC.

It includes a Phase Locked Loop (PLL) core, consisting of a reference divider, phase-frequency detector (PFD) with a phase-lock indicator, ultralow noise charge pump and integer feedback divider.

The LTC6952’s eleven outputs can be configured as up to five JESD204B/C subclass 1 device clock/SYSREF pairs plus one general purpose output, or simply eleven general purpose clock outputs for non-JESD204B/C applications.
