REQ: Internal photos of Cypress CM-397 scandoubler
« on: November 07, 2008, 02:28:25 PM »
I'm after some internal photos (or details of the chips) of the Cypress CM-397 scandoubler

I appreciate that if you try to take it apart you may never get it back together so it's going to take a brave person to try.

It would be very much appreciated.

So you wouldn't be willing to pay for a replacement if it gets Fux0rD in the process then?  :lol:

Aaah, Alex is hunting for a 24-bit SD ASIC, maybe there's something other than usual Averlogic circuitry...am I close enough?

This device has been long reputed to use the Averlogic AL250 (16-bit scandoubler IC) but I noticed yesterday that the capabilities of this scandoubler (scan rate conversion [50Hz->60Hz]and upscaling [720x512 -> 1024x768]) did not tie up with the AL250.

As we can see from these very kindly provided photos and details this actually uses a Sunplus DigiShow SPV311a

MST9883C-LF-110 = Triple 8-bit ADC
W9816G6 = SDRAM

Now time to run off and track down the datasheet for this part.

Sorry for the bump, but I am trying to see the internal photos, since Im planning to buy this.

But I get this error:
