MAX3950: Printed Circuit Card Layout Considerations for 10Gbps Current Mode Logic Inputs on the MAX3950 EVKIT


Abstract: Interfacing 10Gbps current-mode logic (CML) signals using controlled-impedance microstrip signal paths on printed circuit cards requires appropriate material selection and careful attention to layout geometry in order to control crosstalk, jitter and signal integrity. The following example from the MAX3950 10Gbps 1:16 deserializer evaluation kit (EV kit) board illustrates some key points.
