  • Page 5 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.
  • Page 6 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 !

  • Page 9 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 -->...
  • Page 10 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.
  • Page 11 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.
