HIGH SPEED PRE DRIVER AND VOLTAGE LEVEL CONVERTER WITH BUILT IN DE EMPHASIS FOR HDMI TRANSMIT APPLICATIONS

摘要

In an example a high speed pre driver (400) and voltage level converter (405) with built in de emphasis (415A B) for HDMI transmit applications is provided. An exemplary integrated circuit includes a serializer a pre driver coupled to receive a differential input from the serializes and a driver. The pre driver (400) includes all p type metal oxide silicon (PMOS) cross coupled level converter comprising four PMOS transistors (410A D) and two de emphasis PMOS transistors (415A B) forming a de emphasis tap coupled to the output (outn outp) of the cross coupled level converter. The driver is coupled to the pre driver output and is configured to receive a differential input from the pre driver.
