Abstract
A receiver interface for interfacing with an Advanced Technology Attachment Packet Interface (ATAPI) in a first device. The receiver interface includes a converter, a depacketizing circuit, and an ATAPI receiver circuit. The converter converts a first set of signals from a serial bus into a second set of signals. The first set of signals are serial to one another and use low-voltage, differential signaling (LVDS). The first set of signals are adapted to be received on fewer lines and at a faster data rate than possible with an Integrated Disc Electronics (IDE) bus. In contrast, the second set of signals are serial to another and use TTL voltage levels and single-ended signaling. Additionally, the second set of signals use a packet format to represent a packet. The depacketizing circuit disassembles the packet represented by the second set of signals to generate a third set of signals, which are parallel to one another and use TTL, single-ended signaling. The third set of signals represents a payload of the packet. The ATAPI receiver circuit stores a fourth set of signals at a location within the ATAPI in response to the third set of signals. The fourth set of signals representing a portion of the payload of the packet.
