XRT72L54IB [MAXLINEAR]

XRT72L54IB Overview

A Surface Mount-axis mount is used.The telecom interface contains 272 pins.The telecom circuit operates with a supply voltage of 3.3V, giving designers a great deal of freedom.To give designers much flexibility, it uses 190mA as the supply current.Ensure normal operation by setting the temperature to -40°C minimum.It is necessary to set the temperature at the maximum value of 85°C for the telecom IC to function normally.There should at least be 3.135V voltage supplied.Telecommunications device is recommended to supply a voltage lower than 3.465V.Normal operation requires that the supply current be kept at 190mA.With 4 transceivers, it is integrated.
