Hello Gui Kang,

From your brief description, I am not able to discern precisely what you are wanting to design. Please provide more details and specifications. At a minimum, a block diagram would be very helpful.

Thanks for posting on E2E, I'm sure we can get this design defined and recommend the best devices to meet the requirements.

Regards,

~Leonard

Hello Kang,

For FXS SLIC circuit, I would recommend something from silicon labs:

www.silabs.com/.../si3217x-si32911-si32919-single-chip-proslic

For DSP, I would like to recommend C6748 from TI. C6748 has one McASP, two McBSP interfaces, two SPIs which would work really well with FXS SLIC.

Hopefully this helps.

best regards,
