    Abstract
    Serial communication is widely being used from PCs to handheld mobile phones due to very less hardware, low cost, easier design process in comparison to parallel communication. For bit by bit, reliable transmission and receiving at the physical layer it is important for data sequences to have high transition density, low power spectral density, less bit error and reduced bandwidth. This thesis implements the universal serial bus 2.0 (USB 2.0) transceiver Macro cell interface (UTMI) in a generic form to use different low level signaling protocol blocks in other serial communication standards. The code written is synthesizable and verified for correct functionality. The HDL code is a state machine (Mealy machine) implementation from the specification of UTMI. The challenging part of the work was to implement clock and data recovery block as it involved a lot of engineering concepts like control theory, digital electronics and analog circuits. The work presents intricacies in the design of PLL for recovery of clock and data. UTMI helps in faster development of ASIC and provides an abstraction layer for the peripheral developers who are not involved in low level details of physical layer. Finally the results for UTMI implementation are presented.
