Q1
Is the Scarlet just a "Cremson + embedded SDRAM" ?
Q2
Is Orchid basically the same as Scarlet, but without embedded SDRAM ?
Q3
Is Scarlet&Orchid Software-compatible to Cremson ?
Q4
Video Capture Unit of Scarlet&Orchid :
How can analog video signals be input to the interface ?
Q5
Video Capture Unit of Scarlet&Orchid :
Can different video input and display frame rates be used ?
Q6
Can the video input signal be mixed with information by alphablending?
Q7
There is a I2C interface implemented in Scarlet&Orchid.
On which pins is this interface located ?
Q8
Scarlet requires 14,32MHz (4* NTSC) input clock.
Is it possible to use another crystal (e.g.14,25MHz) ?
What is the allowed range of deviation (PLL) ?
Q9
What is the weight (in grams) of the final Scarlet chip (mass production version) ?
Q10
Using SH-3 @ 66 Mhz together with Scarlet :
The "XRDY delay time" is specified with t(RDYD)=7ns (max). In the Hitachi
SH3-spec there is a value given for "Wait setup time" = 12ns (min) @ 66MHz
operation frequency. Under these worst case conditions, the wait line could
eventually cause problems. Did your customers had problems with that ? Do
you have any recommendations ?
Q11
Is the load capacitance specified (C=16pF) valid for all ports of Scarlet ?
Q12
Power consumption figures and temperature of Scarlet :
Q13
DAC power down mode :
If only the digital video interface is used for a digital display, is it
possible for power consumption reduction to save the resistors at Vref-,
AOUTR/B/G-, ACOMPB- and VRO-pin and leave them open or connect them
to GND or Vcc (2.5V or 3.3V?) directly?
Q14
If CCLK and VI(0..7) at SCARLET are not used, what has to
be done with them?
Q15
There are two possible FCRAM-options mentioned in the Orchid-Manual :
16MBitx16Bit with 32bit data bus or 64bit data bus (4 or 8MByte).
Can you please specify which available FCRAM devices can be connected (partnumbers)
Q16
What are the input limitations for the video input of Scarlet/Orchid ?
Q17
How much is the decrease of drawing performance, while using AAF Feature ?
Q18
What can I do to make the Orchid chroma-key function work on the PCI board ?
Q19
Recommendation for using the Orchid with the memory configuration :
2 x SDRAM 128MBit (x32) 64 bit buswidth
Q20
How can I switch on/off the LEDs on the PCI board for testing ?
Q21
What is the correct initialize routine for Scarlet ?
Q22
using the Orchid (MB86292) we want to use a single 32-bit SDRAM
from Micron (MT48LC4M32B2). Do the unused Data lines MD32-MD54
and MDQM4-7 need a pull up resistor to have a known state, or can I leave them open?
Q23
How to connect the TESTx-pins ?
Q24
DCLKO Jitter @ Scarlet
Q25
Bank interleave Scarlet/Orchid
Q26
