High-Speed Inter-Chip USB [HSIC]; a USB chip-to-chip interconnect. HSIC removes the analog transceivers found in normal USB. The maximum trace length defined is 10cm.
HSIC uses 2 signals (strobe, data) in a source synchronous serial interface with 240MHz DDR signaling to provide a 480Mbps USB interface. The electrical interface uses 1.2 volt LVCMOS logic levels. Both Data and strobe are bi-directional utilizing NRZI encoding.
There are five static bus conditions that are used to indicate operation;
Condition .... Strobe .... Data
Idle ......... Hi ........ Lo
Connect ...... Lo ........ Hi
Resume ....... Lo ........ Hi
Suspend ...... Hi ........ Lo
Reset ........ Lo ........ Lo
Other IC to IC Buses.
