3. Inside Details - Powerline

The powerline and coax AV200's have very similar designs, differing only by a small amount of circuitry that couples the DS2 guts to either the AC mains or a single "F" type coax connector. Figure 2 is an photo of the inside of the AV200 Powerline version that shows that most of the interesting circuitry is hidden by a thick aluminum heatsink.

Figure 3 shows the heatsink removed so that you can see the DS2 DSS7700S analog front end devices (the DS9001A has white heatsink compound on it). The other ICs used in the design are RAM, flash (on the underside of the board) and a

The component grouping at the top of Figure 3 is the power supply. You can also see the coupling transformer and associated components clustered near the power receptacle, which connect the AC line and DS2 circuitry. You can also see empty mounting pads for the coax connector and its coupling transformer, which are not loaded in the powerline version at the bottom center of the photo.
