Sorry been overloaded today. I scanned the base design for the 907B at lunch.
Sorry for the large size.
This original design needs some updating because it was not optimized for 1080p more designed for 1080i, 720, 480p
The R6 412 Ohm is responsible for Impedance Matching. If you have a ring or reflection, which can happen, adjust this value.
The original Gain / Gama ( Gain affects gamma on a CRT) .. R2 150 ohm adjust this value.
On the original design they used two ( C30- 35) 22PF with a ferrite. The ferrite is still a good idea because it limits interference coming back into the chip. However two 22 PF caps have too much DE-Peaking for 1080p.
In other words if you have Ring you need to add a higher value. To much reduces the sharpness. This will not help some projectors, like barco the ring is caused internally and putting large caps will eventually get rid of ring but will substantially degrade the image.
If your going through cables most manufactures tend to get rid of the caps. This is bad because the reflections and ring are too great causing shadow and loss of clarity, a balance is needed.
Also the original SIL907 R7 and R8 that feed the power at 1080p cause noise and HDCP handshake issues. I move these 10k values up to 75 ohms. That makes the 1080p picture more stable, have better focus and less bit drop.
There are a couple of other things that I recommend to make the picture better on this chip but I don't have my book with me today.
