- Date Issued
- This paper presents a receiver and a transmitter digital circuit for the USB 2.0 physical layer high speed interface. The circuit operates in 480 Mbit/sec. The receiver consists of a 1-to-8-bit de-serializer, a bit un-stuffer, and a non-return to zero inverted decoder. The transmitter includes an 8-to-1-bit serializer, a bit stuffer, and a non-return to zero inverted decoder. Squelch signal is added to a basic USB 2.0 system for a safe operation of the circuit, and other functions are fully verified USB 2.0 specification. Synthesis, and auto post and routing process are performed with 130 nm process.
