Question
Is the Scarlet just a "C 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 ?
Can the video input signal be mixed with information by alphablending?
There is a I2C interface implemented in Scarlet&Orchid.
On which pins is this interface located ?
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) ?
What is the weight (in grams) of the final Scarlet chip (mass production version) ?
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 ?
Is the load capacitance specified (C=16pF) valid for all ports of Scarlet ?
Power consumption figures and temperature of Scarlet :
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?
If CCLK and VI(0..7) at SCARLET are not used, what has to
be done with them?
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)
What are the input limitations for the video input of Scarlet/Orchid ?
How much is the decrease of drawing performance, while using AAF Feature ?
What can I do to make the Orchid chroma-key function work on the PCI board ?
Recommendation for using the Orchid with the memory configuration :
2 x SDRAM 128MBit (x32) 64 bit buswidth
How can I switch on/off the LEDs on the PCI board for testing ?
What is the correct initialize routine for Scarlet ?
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?
How to connect the TESTx-pins ?
