Any flexibility in adjusting the protocols used in TI's 2.4 GHz proprietary RFICs?

My company has produced 2.4 GHz wireless transceivers for 20+ years. We started designing these radios long before any single chip transceivers were on the market. These radios were designed with discrete amplifiers, mixers, SAW filters, etc. A few of these radios are used in industrial applications are are still produced in 20K-50K quantities yearly.

The customers still using these old discrete radios are requesting that we reduce the cost of these devices. We're open to doing that. In fact, we'd really like to change the design and base it on one of your proprietary 2.4 GHz SoCs or single chip transceivers.

However, we long ago designed a custom packet protocol (with custom dotting patterns, synch word detection, packet length, CRC, etc.) into these designs. Any new SoC or RFIC chip I buy from TI will have its own packet protocol and it certainly won't match ours. Therefore any new design based on your RFICs will not be backwards compatible with the units already in the field. 

I'm pretty sure this is the case as I've never seen any ability to change the packet structure and/or protocol in your chips. I'm sending this in question to confirm that indeed, there is no way I could adjust the packet structure or protocol of any of your 2.4 GHz SoCs or Single Chip Transceivers. 

If I am wrong and there is some flexibility that I'm not aware of, please let me know. 

Thanks,

Mark

    Can you share some more information on your protocol, in this way, we can support you better. We have many customers using protocols that do not necessarily match our packet set-up, but the solutions chosen depend on their requirement. Many customers for instant uses synchronous or asynchronous mode and do the packet handling with their MCU.

    Thanks for your reply. We probably do have decent written documentation for this. We will dig that up in the next few days, polish it up and get back with you.

    Is there a way we can provide that document to you and not have it available over the entire e2e site? This information is certainly old but it's still considered proprietary and we'd just as soon not broadcast it to everyone if possible. 

    Thanks,
