AWR2243: CSI-2

Part Number: AWR2243
Other Parts Discussed in Thread: AWR1642, AWR1843

Hi,

For the AWR2243 it looks like the LVDS/CSI-2 interface was replaced with CSI-2 only. I know this protocol is part of the MIPI camera interface and some CPLD/FPGA devices have built in CSI-2 blocks but not all devices have this. Does TI document the interface requirements for CSI-2 on their chips for implementation in VHDL/Verilog or is that up to the end user to acquire the documentation through the MIPI/CSI-2 Alliance?

What recommendations do you have for capturing the sensor data to an FPGA such as Intel Cyclone V GT or Intel Cyclone 10 GT devices with high speed hardened transceivers.

Best,

p.s. For context, I have purchased the DCA1000EVM, IWR1642BOOST and IWR1443BOOST to prototype some proximity measurements at close range (less than a meter), and am considering AWR2243.  IWR1642 and IWR1443 was chosen due to the application examples available from TI for short range proximity. One example used the on-board DSP and the other did not

  • Hi,

    AWR2243 supports LVDS. Please see in the datasheet Table 3 Device Comparison

    Does your customer need to use LVDS or CSI?

    thank you

  • Hello Alicia,

    In general for proximity measurements we recommend using AWR1642 or AWR1843. These have integrated DSP and a single chip will suffice for you solution.

    2243 is intended for longer range applications and needs an external DSP to be connected to process the data.

    The CSI interface on 2243 follows the standard MIPI protocol, so if you have a MIPI compliant receiver it can be interfaces with 2243. But the control is over the SPI interface between the processor and the 2243 device.

    LVDS interface is also available for debug purpose, but for production we recommend using CSI interface.
