I want to create a pair of circuit boards which work in tandem to transport some analog data over standard CAT5 cables in a digital format. I am looking for someone to do electronic design, component selection, schematic capture, PCB layout, testing and debug of a prototype, and a final "turn"on the PCB design. Altium is preferred, but I can accept other formats.
The incoming data is 6 differential analog signals, one digital signal, and an RS-232 signal. The only signal returned to the source is RS-232. The analog signal should preferably have a 96kHz sample rate. The output should mirror the input: i.e. 6 differential Analog signals, one digital signal, and the RS-232 data.
I have identified an ADC and DAC with parallel I/O which I think would be a good choice, but I'm open to consider other options. I have also identified a 10/100 Ethernet PHY which appears to offer the correct digital transport layer. I believe that the key remaining logic item is an element to control the DACs and package the resultant data for the PHY; I'm leaning toward an FPGA for this function, but would consider a microcontroller.
This also needs an isolated Power Over Ethernet (POE) system; I haven't done any design in this regard, so options are pretty open
I would plan to break the project into the following steps:
(1) Block diagram and main component selection
(2) Detailed schematics of both PCBs
(3) PCB Layout of both PCBs
- At this point I order assembled prototypes for delivery to you-
(4) Code generation, troubleshooting, and system debug
(5) PCB Layout Updates
