World’s First USB 3.0 SSIC Demonstration with a MIPI M-PHY

Yes, we actually showed the first one about 2 months ago where we showed compliance, but we thought you should see an actual application operating.

As a reminder, SSIC is:

• Super Speed Interchip
• For on PCB use of USB 3.0 protocol standards
• Supports only USB 3.0 speeds, No USB 2.0 speeds or slower supported (or needed)
• Saves power because it only turns on to transmit when there is data.
• Saves power because it uses a smaller M-PHY, not a USB 3.0 PHY.
• Saves power because it supports only one USB 3.0 Speed, SuperSpeed USB
• Saves power because it operates at the slowest necessary speed to support the data transfer
• For example, if used with a LTE modem, the M-PHY can operate in Gear 1 mode saving power compared to faster Gear 2 or Gear 3 modes.

SSIC will commonly be used in Wireless chips like WiFi-AC and LTE modems.   This allows you to save power in your mobile phone by using SSIC inside the phone, on PCB to the main mobile application processor.
