WebThis is usually illustrated as a pair of single-ended nominal uncoupled 50 Ω transmission lines (one for each polarity) terminating in to an ideal 100 Ω resistor at the far end or receiver end of the circuit. This is depicted on the left hand side as the “Textbook” 100 Ω Differential Termination. WebAnother way to terminate LVPECL output is to to GND, which provides a DCapply 142Ω -biasing for LVPECL ... The CML output consists of a differential pair of common-emitter transistors with 50Ω collector resistors as the CML output structure illustrated in . Figure 3shows . The outputs of OUT+ and OUT− are typically connecting to
