Abstract
In the fast data communication system, synchronized by a clock source, the loss of data will often occur due to several reasons as a differential routing path between data and clock, a differential propagation delay of components or an unstable phase of clock and data by external noise. In this paper, we describe the ASIC implementation of the data compensation circuit which can detect the data loss from above problems and recovery to original data with stable synchronization. Especially it supports a strong stability and a good BER in the communication system for fast data transfer as optic area. This circuit is implemented by Verilog HDL and available to the digital ASIC implementations related to fast data transfer.
