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 and voltage level converter with built-in de-emphasis for HDMI transmit applications is provided. An exemplary integrated circuit includes a serializer, a pre-driver coupled to receive a differential input from the serializer, and a driver. The pre-driver includes all-p-type metal-oxide-silicon (PMOS) cross-coupled level converter comprising four PMOS transistors and two de-emphasis PMOS transistors forming a de-emphasis tap coupled to the output 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.
