Hi,
We are starting to use using the ADAU1372 to replace an old A/D converter.
We are supplying an external clock (MCLK) of 18.75MHz. I'm basing my calculation on the 19.2MHz example in the datasheet but changing the fraction part to match my needs.
24.576/18.75 = 1/4 * (5 + (6/25))
Code - o/p data sent on the I2C bus:
Reg 0x00
data 0x10
Send data out
Reg 0x01
data 0x00
send data out
Reg 0x02
data 0x19
send data out
Reg 0x03
data 0x00
send data out
Reg 0x04
data 0x06
send data out
Reg 0x05
data 0x2B
send data out
Reg 0x00
data 0x09
send data out
Poll for the PLL lock status
Reg 0x00
data 0x99
send data out
Then to test I'm changing the reg 0x08 (REGULATOR CONTROL REGISTER). To see if I can change the voltage on the output pin from 1.1v to 1.2v, to confirm the A/D is set up and happy.
Reg 0x08
data 0x00
send data out
Current It's not working, any help will be greatly appreciated.
