The LTC6953 is a high performance, ultralow jitter, JESD204B/C clock distribution IC. The LTC6953’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 LTC6953s can be connected together with LTC6952s and LTC6955s using the EZSync or ParallelSync synchronization protocols.
Applications
- High Performance Data Converter Clocking
- Wireless Infrastructure
- Test and Measurement
