Abstract
A plurality of frames of data are transmitted over a serial interface in a manner that limits interference on the interface. This involves generating a pseudo-random number and asserting a read control signal at a moment in time, wherein a timing of the moment in time is influenced by the pseudo-random number. In response to the asserted read control signal, a frame of data is read from a data buffer. The read frame of data is then transmitted over the serial interface. A number of alternative embodiments are possible, such as embodiments in which buffer read operations are triggered based on the buffer fill level, and other embodiments in which buffer read operations are triggered by a timer. By using the pseudo-random number to influence the buffer read operations, timing coherency between the reading of frames is made low, thereby limiting interference.
