Abstract

A low-power multi-level pulse amplitude modulation (PAM) line driver (100) using variable resistors (Rd and Rt) is disclosed for transmitting digital data over controlled-impedance transmission lines (110). The driver comprises two push-pull variable resistor branches (102a, 104a, 112a, with 114a and 102b, 104b, 112b, with 114b), and a middle variable resistor branch (116). The purpose of the two push-pull branches is to generate target voltage (Vop, Von) across the line, and the middle branch ensures the effective impedance of the resistors match the line impedance (Zo). The values of the variable resistors are selected by combinational logic (driver coder logic) whose input is raw data bits (Data(n)). The driver requires a supply voltage being equal or higher than twice the maximum output signal level (2*Vswing). This supply voltage can be a voltage supplied to the chip itself or a regulated supply voltage adjusted to provide a certain voltage swing (Vswing).
