FPGA as router delay simulmator

Altera staff,

I'm new in this forum and I need your help.

okay, I'm looking for peroforming the following application:

I have a number of devices which communicate to each others through analog signals.

what I'm looking for is to use an FPGA bywhich I can interface my devices.

To be clear, with theyour product I should be able to do:

- routing received signal from one device to another

- delaying some signals in specific instance

- using a software interface to perform the desired specifcation.

- I need at least 10 analog inputs and 3 analog outputs.

Specs:

-The analog signal input frequency is about 24KHz

- the delay range is about 0 to 25µsec

- voltage range is +/- 10V for analog inputs and +-5V for the outputs

my questions:

what's the FPGA type that answers to my applications ?

Best Regards.

    well, no FPGAs have analogue inputs - you will need ADCs for that. And I dont think there are many dev boards with that many analgue inputs. So you'll have to build a custom board.

    But from a logic perspective its rather simple. The cheaper cyclones or maybe even a max 5 should be ok.
