Abstract
Methods and Apparatuses are provided for automatically converting a word length of sample data being transmitted over a serial link. A serial interface transmits and/or receives one or more data words comprising digital signals, a bit clock synchronizes transmission of individual bits, and a word clock is used to group the bits into sample words. A desired word length is determined based on the relationship between the bit clock and the word clock during the transmission or reception of a data word. Based on the desired word length, the sample data is either truncated or padded, and an appropriate amount of dither is added to the sample words to reduce the distortion and quantization artifacts introduced by the word length conversion.
