Overview

Product Details

Demonstration circuit 2610A features the LTC6953, an Ultralow Jitter, 4.5GHz Clock Distributor with 11 Outputs and JESD204B Support.

By default, the DC2610A is powered from a single 3.3V supply. An option is provided to power to the DC2610A from dual supplies, allowing for the LTC6953’s output supply pins to connect to an LTC Silent Switcher® and the LTC6953 input supply pin to connect to a low noise LDO.

All differential inputs and seven of the differential outputs are populated with 0.5” spaced SMA connectors. These outputs are AC-coupled with 50Ω transmission lines making them suitable to drive 50Ω impedance instruments. The remaining four differential outputs are terminated with 100Ω.

The LTC6953’s EZSync™ and SYSREF request functions are made available via the LTC6953 SPI interface or the EZS_SRQ SMA/turret connectors. The DC2609A, DC2610A, and DC2611A SMA placement was designed for ease of connection for all multi-part synchronization and SYSREF request modes.

A calibration path is provided to aid in accurate LTC6953 propagation delay measurements.

A DC2026 USB serial controller board is used for SPI communication with the LTC6953, controlled by the supplied LTC6952Wizard™ software.

    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.
