Hey all,
i'm in the last design steps for my DSP-Board (in conjuction with my amplifier),
and since there is an enormous amout of expertise circulating in this forum, i'd be glad to recieve some critique of my layout before i go into assembly.
Did me best so far, but coming from automotive power engineering, mixed signal and "highspeed" designs are not really my strength 😉
Short summary:
It is a simple DSP-board, using the Analog ADAU1463/67 as main-processor, a TI PCM3168 CODEC for ADC/DAC, and a tinysine (CSR) TS8675 as bluetooth source.
The board will be used to source and controll up to 8 TPA32xx-Boards, hence the differential output with significant voltage mas well as some logic signals for each of the four amplifier boards.
Input Supply will be 10-30V, controls like Potentiometers, GPIOs and so on shall be realised individually for each project where the combo is used, connected with ribbon cables.
The schematic regarding BOM-optimization and choice of some components are still WIP, keep that in mind please.
Thanks alot already!
best regards,
Lukas
