Hi All, I picked up a C3088 Color Camera Module (aka. the Cam in the CMU and AVR Cameras). I am interested in connecting the 16-bit outputs as well as the clock, and image framing lines to a 3.3 volt (not 5.0 volt tolerant NetBurner) cpu. Readiing the Omnivision 6620 the actual image sensor on the C3088) manual, I notice that there is with the Omnivision
6620 a means to power the output pins with a seperate power source at 3.3 volts - via the DOGND and DODDD pins on the 6620.I see 5 unused through-hole solder pads on the C3088 module that correspond to the same name lines as the image sensor - DGND, DVDD, DOVDD, AGND, AVDD .... My question to the CMU and AVR ( BTW, I have an AVR CAM on a hexpod- works great) cam experts if anyone has played with these unused C3088 module lines to add an additional 3.3 volt rail, to allow the output pins to output only 3.3volts ?
My current solution is a Max 7000 CPLD chip (happen to have had a few on hand) which I have tied the Digital Output lines from the C3088 module to 3.3 volts - but it is kludgy, heavy, and sucks alot of power, and looks kindof silly - this big 'ole 88 pin PLC socket.....
7400LVC logic would take either lots of chips or a single level transciever (and surface experience) both options i do not like too much....Any ideas ? Regards, John LeClair
