Layout Information
The evaluation board provides a guideline of how to lay out the board to obtain the maximum performance from
the ADS5400. General design rules, such as the use of multilayer boards, single ground plane for ADC ground
connections, and local decoupling ceramic chip capacitors, should be applied. The input traces should be
isolated from any external source of interference or noise, including the digital outputs as well as the clock
traces. The clock signal traces should also be isolated from other signals, especially in applications where low
jitter is required like high IF sampling. Besides performance-oriented rules, care must be taken when considering
the heat dissipation of the device. The thermal heat sink should be soldered to the board. Check with factory for
ADS5400 EVM User Guide for the evaluation board schematic.
