Reverse Engineering of the Cisco HWIC-3G-CDMA PCB
Not really an issue, but I wanted to have a place to discuss this....
I have been looking for the mating connector part # (or a way to build a footprint and manually stuff a connector) and I've not been able to locate one that this board can easily plug into. once you remove the i/o plate, there are good places to securely fasten the boards together too.
It looks like it should be possible to make a 'personality board' with signal conditioning, aux components (ADC, etc...), power, and bitstream capabiliites, but it won't be very useful without a mating connector strategy... Is there a connector we can purchase for this? Or are scrap routers the cheapest solution?
Since there doesn't really seem to be a good place to discuss this board, I recently acquired the 3G GSM version. One difference I've noticed is that the chip that could be a microcontroller (tssop14 package) leads a little down a rabbit hole on this board.
Sorry the board is a little dusty, it's how it came and i haven't taken the time to clean it yet. Here's the seems to have "CV9622" on it, which after a little bit of searching, only seems to be referenced on a list of discontinued NXP parts (https://www.nxp.com/wcm_documents/products/eol/dn62_a.pdf). P83LPC913FDH/CV9622, is a replacement part for a customer specific "ROM PART of the LPC900 Family". I think it's safe to assume that's this part. So if I'm reading that right, it was a custom chip for one customer, but P89LPC913 (https://www.nxp.com/docs/en/data-sheet/P89LPC912_913_914.pdf) is probably very similar.
Obviously doesn't make this part of the board any more useful, but hopefully its useful.
