We are designing a small 16 Channel Audio Power-Amplifier using Tas5508C (and some Tas5342). The recommended design uses a Crystal (Pin 19 and 20) to supply a reference clock as long as there is no master clock (Pin 63).
What ist the best way to supply the reference clock (crystal 13.5MHz) to both of the Tas5508c?
1. To use two crystals, one for each Tas5508c? (We want to avoid this!!)
2. To use one crystal for the first Tas5508c as recommended and to connect PIN 20 of the first Tas5508c to the same Pin of the second Tas5508c?
3. To use a crystal oszillator and to connect its output to each Pin 20 of the two Tas5508c?
In reference to points 2 and 3. What'a about PIN 19. Do we leave it open?
We program the properties of the Tas5508c by a small PIC-Processor. Is it possible to change the Tas 5508c I2C interface adress so we can program two Tas5508c by using just one bus?
Thank you for your help.
Sincerely
Cornelius Bradter
