An integrated circuit for a high speed data communication system with improved Electrostatic Discharge (ESD) protection is provided. The circuit includes first and second monolithic transformers. An ESD device connected between the first and second monolithic transformers. There are first and second on-chip spark gaps for forming low impedance grounds during ESD events. The first on-chip spark gaps are electrically connected to the first monolithic transformer and the second on-chip spark gaps are electrically connected to the second monolithic transformer.
