PCB Design

As this All-In-Wonder multimedia card is based on the ATI RADEON 9700 PRO graphics chip, it has a lot in common with its gaming brother. In fact they differ less than RADEON 8500 and All-In-Wonder 8500 used to.

 

First, let’s take a look at the bracket of the card. It carries (from left to right, from top to bottom) an 8-pin Mini-Din video input, antenna input, 10-pin Mini-Din video output and DVI-I connector for the display. Unlike RADEON 9700 PRO graphics cards, All-In-Wonder 9700 PRO has only one display output. It is a DVI-I connector that transfers both digital and analog signals. As for the antenna output, it is intended for a coaxial cable with an F-connector. There is no adapter coming with the multimedia card that would allow attaching antennas with ordinary coaxial connectors that are used in many TV-sets and antennas.

I can’t say definitely how the wiring for this DVI-I output is laid out. The card can probably output two independent signals onto the single DVI-I connector so that you could connect two displays at a time by means of some special splitter. Still, the card comes only with a standard DVI-VGA adapter that allows attaching an analog display to the card. Thus, it seems like you cannot use the HydraVision capabilities implemented in RADEON 9700 PRO chips, that is, dual-display configurations. On the other hand, there is a possibility to have both: a display and TV-set connected to the computer with a different picture on each. But still, it’s not quite good to use a TV-set as a second display. It doesn’t suit well for text or graphics.

An analog signal receiver, or, simpler, TV-tuner from Philips, takes a lot of the PCB area. This tuner also influenced the placement of some other components of the card. For example, the power supply circuit of RADEON 9700 PRO includes two chips that are placed on the back side of the card and covered with a heat-spreader. Here, this power supply circuit is on the front side, below the tuner. You can recognize the two chips by their heat-spreaders.

Under the tuner block, there is a four-pin connector. It is CD-Out that must be connected to the CD-In of the sound card to transfer the sound of the received channels.

Rage Theater 200 chip is soldered to the back side of the PCB. It is responsible for video input implementation of the multimedia card. Rage Theater chips are not installed on ordinary gaming RADEON 9700 PRO based cards because these cards don’t support video input, while TV-Out functions are implemented in the graphics chip itself. Let’s see what this Rage Theater is like.
