| description: | |
| The PS8640 is a low power MIPI-to-eDP video format converter supporting |
| mobile devices with embedded panel resolutions up to 2048 x 1536. The |
| device accepts a single channel of MIPI DSI v1.1, with up to four lanes |
| plus clock, at a transmission rate up to 1.5Gbit/sec per lane. The |
| device outputs eDP v1.4, one or two lanes, at a link rate of up to |
| 3.24Gbit/sec per lane. |
