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 !

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.
