ABSTRACT:
A high-speed serial-link driver transmits a differential data signal to a conventional differential receiver via a differential channel. The driver employs termination voltages that are high, relative to the supply voltage employed by the transmitter core logic, to support communication with legacy devices. Cascode amplifiers using an adaptive biasing scheme allow the driver to include voltage-sensitive, high-performance transistors despite the relatively high termination voltage.
