The inputs have a 100Ω resistor across the differential pair, placing the receiver termination as close as possible to the input stage of the device.

DS15BR400, DS15BR401 www.ti.com SNLS224G – AUGUST 2006 – REVISED APRIL 2013 Bypass capacitors should be placed close to VDD pins. Small physical size capacitors, such as 0402, X7R, surface mount capacitors should be used to minimize body inductance of capacitors. Each bypass capacitor is connected to the power and ground plane through vias tangent to the pads of the capacitor. An X7R surface mount capacitor of size 0402 has about 0.5 nH of body inductance.

Their outputs can be DC-coupled to most common differential receivers. Figure 14 illustrates typical DC-coupled interface to common differential receivers and assumes that the receivers have high impedance inputs.
