MAX9121 Evaluation Kit
General Description
The MAX9121 evaluation kit (EV kit) contains a flow-
through low-voltage differential signaling (LVDS) quad
differential line driver (MAX9123) and receiver
(MAX9121). The differential line driver accepts LVTTL or
LVCMOS inputs and translates them to LVDS output sig-
nals. 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 MAX9121 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 MAX9121 EV kit can also be used to evaluate the
MAX9122, which is the same as the MAX9121 but with
integrated 107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.
