  • Hello Sam,

    The DLPC4422 has not been discontinued. We do have a new revision that was been released as of 2020, the DLPC4422AZPC. It looks like our website needs to be updated with this latest part. Let me get with folks here at TI to fix this.

    The 7540 is a new release, that works with certain DMDs. The datasheet for the 7540 is on ti.com under lit number DLPS206 (can search on this on ti.com).

    The DLPC4422 communicates with DMDs through a 2x LVDS interface. The DLPC7540 uses a high speed serial interface (HSSI), and since the DMD must be designed for this type of input, only certain DMDs work with certain controllers. This means that the DLPC4422 does not work with the HSSI DMDs that you mention (DLP651, DLP650).

    If you have further questions on our offerings and what would be best for your customer's application, I can make a friend request and we can follow up offline.

    Please let us know if this info resolves your initial questions.

    Thanks,

    Matt

  • Sam,

    As a follow up to what Matt responded, here's a summary of the DMD products that are used with the DLP4222 or DLPC7540.

    Also I'm attaching a one pager that briefly compares DLPC4422 and DLPC7540. This can help in deciding which product to recommend your customer.
