Q15:

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 .

Q16:

What are the input limitations for the video input of Scarlet/Orchid ?

Scarlet or Orchid can accept variable formats under the limits shown below

max 720 pixels/raster
max 511 rasters/field
max 27MHz CCLK freq

Q17:

How much is the decrease of drawing performance, while using AAF Feature ?

Anti-aliasing line's performance is 30-40 % of normal line's performance.

Q18:

What can I do to make the Orchid chroma-key function work on the PCI board ?

Unfortunately, there are some hardware-bugs on the Orchid board which have to be fixed :

1) Polarity of clamp pulse (positive pulse must be given)
2) Lack of load resistor at RGB output of LM1279A
(390ohm resistors must be connected between RGB out and GND)

3) Over amplitude of DAC because of improper load in external sync mode. 75ohm load
resistor should be added in parallel with existing 75ohm load.

4) Noise
If above problems are removed, then video level gets proper, but the signal might be noisy.
