Re: Anyone know how to fix 2wires that wont sync? said by An_Onymous :
Not like you can order the big SoC easily from the vendor easily or that replacing the BGA would make any economic sense for you.
I would recommending looking at the driver/receiver chips in your bone pile. That's the soic-8 right next to the sticker SB10A in picture (ST516V6). It should be very common froml the analog chip vendors were selling their DSL driver/receiver chips - fancy opamp parts.
You are looking at a $1 part and a 2 minutes replacement job.
The 2wire doesnt have such a chip. It has a 100 pin flat pack frontend chip (ST20184). It does the work for sync in a 2wire., Digital out is fed into the microprocessor, and vice versa. |
