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.
