MAX9124 Evaluation Kit Evaluates MAX9124/MAX9125/MAX9126 The MAX9124 evaluation kit EV kit contains a low-voltage differential signaling LVDS quad differential line driver MAX9124 and receiver MAX9125 . The differential line driver accepts LVTTL or LVCMOS inputs and translates them to LVDS output signals. The receiver accepts LVDS inputs and translates them to singleended LVCMOS outputs. Both circuits operate with high data rates and low power dissipation. The MAX9124 EV kit is designed with controlledimpedance traces in a four-layer PC board. It is specially 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 addition, a 1.2V power-supply input is provided for testing the driver’s 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 nominal termination resistors. Additional pads on the board are provided for dynamically driving the enable and disable control signals with a pulse generator. o Independent Quad Driver MAX9124 and Quad Receiver MAX9125/MAX9126 Circuits o >500Mbps 250MHz Switching Rate MAX9125/MAX9126 >800Mbps 400MHz Switching Rate MAX9124 o Supports Testing of Twisted-Pair Cables o Controlled-Impedance Signal Traces o 16-Pin TSSOP Package o Fully Assembled and Tested Ordering Information PART TEMP RANGE IC PACKAGE MAX9124EVKIT 0°C to +70°C 16 TSSOP Note To evaluate the MAX9126, request a MAX9126EUE free sample with the MAX9124EVKIT.
