The MAX4951 evaluation kit (EV kit) provides a proven design to evaluate the MAX4951 dual-channel buffer. The EV kit contains four sections: an application circuit, a characterization circuit, and two calibration traces.
The application circuit is designed to demonstrate the use of the MAX4951 in redriving serial-ATA (SATA) and eSATA Gen I and Gen II 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 MAX4951 (U1) device. All traces in the application circuit are 100Ω differential controlled impedance.
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 supply.
