LTC6952 Series

The LTC6952 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. Each output has its own individually programmable frequency divider and output driver. All outputs can also be synchronized and set to precise phase alignment using individual coarse half-cycle digital delays and fine analog time delays.For applications requiring more than eleven total outputs, multiple LTC6952s can be connected together using the EZSync or ParallelSync synchronization protocols.ApplicationsHigh Performance Data Converter ClockingWireless InfrastructureTest and Measurement
