Updated Interface Standards Table – MIPI HSI, HSIC, UniPro, UniPort, LLI, C2C

by Kurt Shuler, On May 17, 2012

[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.
