Abstract:
1. Apparatus for automatically converting a length of data words transmitted as a serial bit stream on a data line, wherein a bit clock signal identifies individual bits in the bit stream and a word clock signal identifies groups of bits in the bitstream comprising data words, the apparatus comprising: a serial port coupled to the data line, the bit clock signal, and the word clock signal for communicating with another device; word length measuring circuitry that receives the bit clock signal and the word clock signal through the serial port and in response determines a word length of the data words being transmitted through the serial port; dither generation circuitry that generates dither responsive to the determined word length; and conversion circuitry that converts the transmitted data words to the determined word length by truncating the transmitted data words responsive to a difference between the determined word length and a desired word length and applies the generated dither.
