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, char-
acterization 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 100I differential controlled-
impedance traces.
The characterization circuit is provided for eye diagram
evaluation using SMA connectors and 50I controlled-
impedance traces. This section is powered by an external
+3.3V power supply.
