TSH94 is a wide bandwidth OP AMP.
Here is the datasheet.
You can use any samilar OP AMP to replace the TSH94.
The better the OP AMP, the better frequency response you have.

For frequncy response:
That's depends on the OP AMP.
I choose TSH94.
The bandwidth of TSH94 is 150MHz.
The most important is that the frequency response of this OP AMP is very flat.
I have measured the output signal. 30MHz bandwidth is guranteed.
For RGB-->YPbPr converter:
Here is...
Stacy, I also found that the Chroma Upsamling Error becomes very important for HDD/DVD+RW recoder. As I am designing the Progressive Scan part for a HDD player, I record a Movie in our labortory. The DVD player to play the Movie disc has such problem. And the HDD recoder has the same problem...
Stacey, There is a good test disc for you: A Few Good Man from Columbia Pictures This disc have 4X3 and 16X9 version on the same disc. In the 16X9 version, there is no problem. In the 4x3 version, there are so many combing errors. Such as at 5'20". I have checked with Faroudja...
The important improvement of DVI is to support non-compression digital data up to UXGA. Fireware or IEEE1394 is only 400MBPS. It is to slow to transfer HDTV. Now, people in consumer electronics are interested in HDMI/DMI/DVI-CE. This maybe becomes standatd interface of HDTV in the future...
- A progressive scan DVD player with a native 480p display (like sony hdtvs) is better than a display that scales a signal up to 1080i.
Yes, 480P is the best for NTSC disc.
I had scaled it to 576P/SVGA/XGA/HDTV and found that the vertical resolution becomes worse.
- DVI is going to be...
Does it has progressive scan input?
If so, it's much better to use a PDVD player.
As I know, only a few 100HZ TV has 3:2 pull down when they do de-interlacing.
