Working Principle

The MAX9157EGJ+T works by connecting a high-speed source to a differential line via a 1-to-8 automatic equalizer. The line receiver then automatically adjusts its gain settings to match the source\'s output. The device then monitors the signal along the differential line and outputs the remaining data on its outputs. In addition, the device utilizes an internal EMI-optimized filter, which helps reduce any EMI from the source signal, resulting in an improved signal-to-noise ratio.

The MAX9157EGJ+T operates at a maximum frequency of 700 MHz (GHz) and features an integrated programmable termination resistor, allowing the receiver to adapt to lower impedances. It also features an adjustable gain setting, allowing the user to optimize the device’s performance for a wide range of applications. Furthermore, its low-skew receiver clock output enables direct connection to FPGAs, memories and synchronous logic devices.
