MAX9124 Evaluation Kit
General Description
The MAX9124 evaluation kit (EV kit) contains a low-volt-
age differential signaling (LVDS) quad differential line
driver (MAX9124) and receiver (MAX9125). The differ-
ential line driver accepts LVTTL or LVCMOS inputs and
translates them to LVDS output signals. The receiver
accepts LVDS inputs and translates them to single-
ended LVCMOS outputs. Both circuits operate with
high data rates and low power dissipation.
The MAX9124 EV kit is designed with 50鈩?controlled-
impedance traces in a four-layer PC board. It is spe-
cially designed for direct differential probing of the
LVDS I/O. Connection points are provided for the
attachment of a cable to carry the LVDS signals.
The EV kit operates from a single 3.3V supply. In addi-
tion, a 1.2V power-supply input is provided for testing the
driver鈥檚 high-impedance propagation delays. A separate
supply option for the driver and receiver allows testing of
the common-mode performance of the receiver.
The MAX9124 EV kit can also be used to evaluate the
MAX9126, which is the same as the MAX9125 but with
integrated 115鈩?(nominal) termination resistors.
Additional pads on the board are provided for dynami-
cally driving the enable and disable control signals with
a pulse generator.
