[Note: I updated the table below based on Ariel Lasry’s feedback. Thanks Ariel!]
I have updated the table below to list the PHY required for each standard. Hope this helps!
I also have it below as a text table for your cut-and-pasting pleasure:
| Standard | Release Date | Unidirectional Throughput | Pins/Signals/ Channels | Low Latency | PHY required |
|---|---|---|---|---|---|
| MIPI HSI | 2003 | 200 Mbit/sec | 8 | No | MIPI HSI PHY |
| USB HSIC | 2007 | 480 Mbit/sec | 2 | No | USB 2.0 HSIC PHY |
| MIPI UniPro, UniPort-D, and UniPort-M* | 2007 | 2,900 Mbit/sec per HS-G2 lane 5,800 Mbit/sec per HS-G3 lane |
2 pins per unidirectional lane | No | MIPI D-PHY or M-PHY |
| MIPI LLI* | 2011 | 2,900 Mbit/sec per HS-G2 lane 5,800 Mbit/sec per HS-G3 lane |
2 pins per unidirectional lane | Yes ~80 ns | MIPI M-PHY |
| C2C | 2010 | 6,400 Mbit/sec | 16 | Yes ~100ns | No |
* Although UniPort-M and LLI both use the MIPI M-PHY, the UniPort standard has higher protocol efficiency than LLI (97% versus 66%). This is because the primary purpose of UniPort is high throughput connectivity while the primary purpose of LLI is low latency.
