List of questions: Go to Question Is the Scarlet just a "Cremson + embedded SDRAM" ? Is Orchid basically the same as Scarlet, but without embedded SDRAM ? Is Scarlet&Orchid Software-compatible to Cremson ? Video Capture Unit of Scarlet&Orchid : How can analog video signals be input to the interface ? Video Capture Unit of Scarlet&Orchid : Can different video input and display frame rates be used ?
Graphic Controller frequently asked questions Jan 2003 MB86291 SCARLET AND MB86292 ORCHID QUESTIONS : back to top Is the Scarlet just a "Cremson + embedded SDRAM" ? No ! Scarlet is NOT just the combination of Cremson and SDRAM. We should be aware about the following major functional upgrade...
back to top Is Orchid basically the same as Scarlet, but without embedded SDRAM ? The major difference is in fact the SDRAM which is limited to 2 MB (16 Mbit) in the Scarlet device. For all applications which require more than 2 MB, the Orchid can be used. In this case up to 32MB of SDRAM and FCRAM can be connected.
back to top Can the video input signal be mixed with information by alphablending? Yes, for example it is possible to put text or graphics on the C-layer alphablended on top of the video (on W-layer). back to top There is a I2C interface implemented in Scarlet&Orchid. On which pins is this interface located ? The I2C pins of Scarlet are : 184 and 185 For details, see the I2C description of Scarlet !
Q12: back to top Power consumption figures and temperature of Scarlet : Testcase: running 3D graphics demo for 10 minutes : 1. DAC Power down mode off (default) 1-1. Measurements The Temperature of package : 47 degree The Temperature of room(Ta): 25 degree The current consumption : 630mA @VDDI-pin(2.5V) 6mA @VCC-pin(2.5V)
Q15: back to top There are two possible FCRAM-oprions mentioned in the Orchid-Manual : 16MBitx16Bit wth 32bit databus or 64bit databus (4 or 8MByte). Can you please specify which available FCRAM devices can be connected (partnumbers) SDR SDRAM type 16Mbit x16bit FCRAM Parts number:MB81E161622 Orchid is able to connect 2 or 4 devices of that type .
Q19: back to top Recommendation for using the Orchid with the memory configuration: 2 x SDRAM 128MBit (x32) 64 bit bus width Example type : MT48LC4M32B2TG The following both connections are OK : Orchid MA12 --> SDRAM BA1 Orchid MA13 --> SDRAM BA0 Orchid MA12 -->...
Q21: back to top What is the correct initialize routine for Scarlet ? To initialize the Scarlet correctly, you have to follow these steps : 1. Hardware reset sequence : after power-on, XRESET and S must be L to issue a reset S must be L for min 500ns after S is H, XRESET must be held low for min 300us 2.
Q24: back to top DCLKO Jitter @ Scarlet 1. If the Clock comes from the internal PLL Although it depends on stability of supplied power for PLL, reference values are as follow. Cremson/Scarlet -150ps to +180ps 2. If the Clock is given via DCLKI If DCLKI does not include jitter, DCLKO does not include jitter also.
