AM620-Q1: AM620-Q1 MIPI CSIRX Electrical Level

Chu Allen
Intellectual 830 points
Part Number: AM620-Q1

Tool/software:

Hello,
In the AM620-Q1 data manual, it is recommended that the voltage of VDDA_1P8_CSIRX0 be 1.8V. If a MIPI camera with 1.1V or 1.2V is connected, does it require level conversion? At the same time, CSIRX0 is compatible with MIPI DPHY v1.2 on 7.8.8. From here, it can be directly connected to a 1.1V or 1.2V MIPI camera. Which of these two information should be used?

    Hello Chu Allen,

    Thank you for the query.

    The 1.8V is the IO supply and not IO level.

    7.11.5.3 CSI-2
    Note
    For more information, see the Camera Streaming Interface Receiver (CSI_RX_IF) section in the
    device TRM.
    The CSI_RX_IF deals with the processing of the pixel data coming from an external image sensor. It is a key
    component for the following multimedia applications: camera viewfinder, video record, and still image capture.
    The CSI_RX_IF has a primary serial interface CSI-2 port (CSIRX0) compliant with the MIPI D-PHY RX
    specification v1.2 and the MIPI CSI-2 specification v1.3, with 4 differential data lanes plus 1 differential clock
    lane in synchronous mode, double data rate. Refer to the MIPI specifications for timing details.
    • Support for 1,2,3 or 4 data lane mode up to 1.5Gbps
