A synchronous serial protocol is used to transfer data from a host processor (102) to multiple CODECs (112) operating at differing speeds and from such CODECs (112) back to the host processor (102) across a bidirectional pair of serial links (134, 136). A link speed fast enough to accommodate all operating...http://www.google.fr/patents/US6128317?utm_source=gb-gplus-shareBrevet US6128317 - Transmitter and receiver supporting differing speed codecs over single links
