The MAX4952A evaluation kit (EV kit) provides a proven design to evaluate the MAX4952A dual-channel buffer. The EV kit contains four sections: an application circuit, characterization circuit, and two calibration traces.
The application circuit (Figure 1a) is designed to demonstrate the MAX4952A IC's use in redriving Serial-Attached SCSI (SAS) and Serial ATA (SATA) 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 MAX4952A (U1) device. All traces in the application circuit are 50Ω single-ended, controlled-impedance traces.
The characterization circuit (Figure 1b) is provided for eye diagram evaluation using SMA connectors and 50Ω
single-ended controlled-impedance traces. This section is powered by an external +3.3V supply.
