Overview and key speciﬁcations

Super Speed Inter-Chip (SSIC) is an optimized inter-chip version of USB3.0. The PHY layer will be MIPI MPHY and the protocol layer will be super speed USB 3.0. SSIC supports USB 3.0 speeds of up to 5 Gbps. The M-P M-PHYs are available in three speeds called Gears:

HY standard consumes lower power and offers greater ﬂexibility than USB 3.0 PHYs.

Gear1 opera

tesat1.25Gbpsor1.45Gbps

Gear2 at 2.5 Gbps to 2.9 Gbps

Gear3upto5.8Gbps

In addition, M-PHYs can have 1, 2, or 4 lanes.

The following summarizes the key features of SSIC:

Support for the Super Speed protocol only as deﬁnedin[USB3.0]

Optimiz

ed for power, area, cost and EMI robustness for embedded inter-chip interfaces

Compliant with the Type-I M-PORTs from the MIPI M-PHY speciﬁcation [M-PHY]

Support for x1, x2, and x4 LANE conﬁgurations

SSIC has been designed to replace a standard SuperSpeed Controller and PHY with an implementation that maps the SuperSpeed controller on the MIPI M-PHY.

AllinformationcommunicatedinthePWM-BURSTand HS-BURST states shall be 8b10b encoded as per the data and control symbols assignments prescribed in [M-PHY] and the symbol mapping a ssignment described in Table 1. Data symbols shall be directly mapped as per the assignment described in [M-PHY].

Zoom

Zoom in to see a detailed view of the packet. Drag the mouse over t he region of interest , click on Zoom 1 On to zoom over a region. Zoom Controls can be accessed from Horiz/Acq menu.

SSIC decode shows up in a hierarchical view as shown below.

Layers

The lowermost layer is the 8b10b decode. This decodes the packets as K and D codes. The packets are shown in this layer without de-scrambling.

Next is the PHY layer decoding. Here the data is de-scrambled and shown as Data and Control Characters with hex value.

The n ext layer is LNK decode. Here the packets are grouped into Ordered Sets like TS1, TS2, HPStart and so on. The topmost is the PKT layer. This shows the SSIC packets like DP, LMP, TP and ITP. You can collapse and expand each of these layers by clicking on the icon o n the left. Clicking on ‘+’ expands the view and clicking on ‘–’ collapses the view.
