Abstract:
A transmission interface in a first device including an Advanced Technology Attachment Packet Interface (ATAPI) for interfacing to a serial bus, the transmission interface comprising:a. a transmission ATAPI circuit coupled to the ATAPI generating a first set of signals representative of a change in contents of the ATAPI, the first set of signals being parallel to one another, and using Transistor-Transistor Logic (TTL) voltage levels and single-ended signaling; b. a packetizing circuit packetizing the first set of signals to generate a second set of signals representing a packet, the packet having a payload representing the change in the contents of the ATAPI, the second set of signals being parallel to one another and using TTL voltage levels and single-ended signaling; and c. a converter converting the second set of signals into a third set of signals, the third set of signals being coupled to the serial bus, the third set of signals being serial to one another, and using low voltage level, differential signaling and being capable of being transmitted using fewer wires than available in an IDE bus, the converter supporting a faster data rate than an IDE bus.
