Design structure for an automatic driver/transmission line/receiver impedance matching circuitry |
摘要 |
A design structure for an impedance matcher that automatically matches impedance between a driver and a receiver. The design structure for an impedance matcher includes a phase-locked loop (PLL) circuit that locks onto a data signal provided by the driver. The impedance matcher also includes tunable impedance matching circuitry responsive to one or more voltage-controlled oscillator control signals within the PLL circuit so as to generate an output signal that is impedance matched with the receiver.
