Evaluates: MAX4951AE
2 ______________________________________________________________________________________
Quick Start (Application Circuit)
Recommended Equipment
• MAX4951AE EV kit
• +5V power supply
• Two SATA cables
• SATA device (e.g., hard drive)
• SATA host (e.g., PC)
Procedure
The MAX4951AE EV kit is fully assembled and tested.
Follow the steps below to verify board operation:
1) Verify that all jumpers are in their default position, as
shown in Table 1.
2) Connect the first SATA cable from the PC to the host
(J1) connector on the EV kit.
3) Connect the second SATA cable from the device
(J2) connector to the SATA device.
4) Verify communication between the host PC and
SATA device.
Detailed Description of Hardware
The MAX4951AE evaluation kit (EV kit) evaluates the
MAX4951AE dual-channel buffer. The MAX4951AE is
designed to redrive Serial-ATA (SATA) and external
Serial-ATA (eSATA) signals. The EV kit is divided into
four sections: application circuit, characterization circuit,
and two sets of calibration traces.
The application circuit utilizes 100I differential con-
trolled-impedance traces and provides two SATA con-
nectors (J1 and J2), allowing for evaluation of the
MAX4951AE in a SATA environment. The characteriza-
tion circuit utilizes 50I controlled-impedance traces and
SMA input/output connectors, allowing for eye diagrams
and input/output return-loss measurements.
The lower half of the MAX4951AE EV kit provides two
sets of calibration traces, all of which are matched to the
trace lengths in the characterization circuit. These traces
provide a reference for determining the performance of
only the MAX4951AE device when evaluated in the char-
acterization circuit.
The MAX4951AE has a cable-detect feature (CAD) that
reduces power consumption to < 1mA when a drive is
not connected, and permits normal functionality, when a
cable and drive are connected to J2.
Application Circuit (U1)
The application circuit provides the means for evaluat-
ing the MAX4951AE in a SATA application. This section
of the EV kit provides two SATA connectors (J1 and J2),
one for connection to a SATA host (e.g., PC) and the
other for connection to a SATA device (e.g., hard drive).
