Evaluation Kit for the MAX14972 (MAX14972EVKIT) (MAX14972EVKIT)The MAX14972 evaluation kit (EV kit) provides a proven design to evaluate the MAX14972 dual SuperSpeed USB 3.0 equalizer/redriver utilizing programmable input equalization and output deemphasis to reduce deterministic jitter, restore output levels, and meet USB 3.0 compliance. This allows optimal placement of key SuperSpeed USB 3.0 components and allows longer circuit-board traces or cables. The EV kit PCB contains four sections: application circuit, characterization circuit, and two calibration traces.
The application circuit is designed to demonstrate the IC's use in equalizing/redriving the USB signals. This section of the EV kit operates from a +5.0V USB supply that is regulated by an on-board +3.3V LDO regulator powering the U1 device. All PCB signal traces in the application circuit are a combination of 100Ω differential and 50Ω single-ended controlled-impedance traces. The characterization circuit is provided for eye diagram evaluation using SMA connectors and controlled-impedance traces. This section is powered by an external +3.0V to +3.6V power supply.
The calibration trace section is provided as a reference to deembed the performance of the IC from the traces and SMA connectors.
The IC is available in a 24-pin (4.0mm x 4.0mm) TQFN package with an exposed pad.
