Abstract
A low-voltage differential signal (LVDS) driver includes at least two programmable fingers operable to drive a signal and at least two pre-drivers. Each pre-driver is associated with one or more of the programmable fingers and is operable to enable or disable the associated one or more programmable fingers. An enabled programmable finger drives the signal and contributes to the capacitive loading of the driver, and a disabled programmable finger does not drive the signal and does not contribute to the capacitive loading of the driver.
