  • Additive Output Jitter 65fsRMS (ADC SNR Method)
  • EZSync™, ParallelSync™ Multichip Synchronization
  • Eleven Independent, Low Noise Outputs with Programmable Coarse Digital and Fine Analog Delays
  • Flexible Outputs Can Serve as Either a Device Clock or SYSREF Signal

  • –40°C to 125°C Operating Junction Temperature Range

Product Details

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

    LTC6952 Wizard

    The LTC6952Wizard software provides appropriate LTC6952 and LTC6953 devices settings and LTC6952 loop filter component values with a click of a button. Different system scenarios may be tried, and then each output’s time-domain waveform and frequency-domain phase noise and jitter may be plotted.
