The MAX4952B evaluation kit (EV kit) provides a proven design to evaluate the MAX4952B dual-channel redriver. The EV kit contains four sections: application circuit, characterization circuit, and two sets of calibration traces.
The application circuit is designed to demonstrate the MAX4952B IC's use in redriving SATA and SAS signals. This section of the EV kit operates from an external +5V supply that is regulated by an on-board LDO to +3.3V, which powers the MAX4952B (U1) device. All traces in the application circuit are 100Ω differential controlled-impedance traces.
The characterization circuit is provided for eye diagram evaluation using SMA connectors and 50Ω controlled-impedance traces. This section is powered by an external +3.3V power supply.
