Semiconductor device including a high-speed receiver being capable of adjusting timing skew for multi-level signal and testing equipment including the receiver

Abstract

A semiconductor device including a signal generator and decoding and timing skew adjusting circuit is provided. The signal generator is configured to receive n multi-level signals having m signal levels and convert the n multi-level signals into n*(m−1) single level signals having two signal levels. The decoding and timing skew adjusting circuit is configured to receive the single level signals, perform a predefined operation on the single level signals to generate an output signal, and compensate for timing skew between the n multi-level signals, using the single level signals. The n and m are natural numbers, where n>=2 and m>=3.
