I'm using the codec ad1934 to have 2 channels with I2S protocol but I can't find several informations in the datasheet. I'm using a 16,934 mHz crystal oscillator for the mclk but it doesn't run. All the register values are at 0x00.…
I want to hook up a AD1934 Audio DAC to a SigmaDSP processor.
The control will be done by an external microcontroller using I2C.
The problem is that the datasheet is unclear about how to use I2C or wether it even supports it.
There are several…
I am trying out a weird combination to make the AD1934 work.
This is my register configuration:
PLL clock control 0 : 0b10001000 (Input 256xfs, 256 x fs output at MCLKO, internal MCLK enable)
PLL clock control 1 : 0b00000000 (DAC clock source and clock…
I am want to use AD1934 to design my audio system , but I not found any reference design or EVB information on website. Could you help me to use AD1934 ?
Dear support team,
I want to know total delay of AD1934.
In datasheet, Group delay of DAC interporation filter is 42us@192kHz.
Is it total delay?
If no, please teach me total delay(Analog input to output register, not include shift time of I2S)
I'm using an AD1934 DAC for my product and the datasheet recommends some component values for the Loop Filter (see https://www.analog.com/media/en/technical-documentation/data-sheets/AD1934.pdf p.25, Loop Filter for LRCLK)
From AD1934's datasheet, I understand that I can run this device without the PLL. My case is the following :
- AD1934 is master on the I2S link (the device outputs both the bit clock and the L/R clock)
- Stereo data, bit clock at 64xFs, 16-b data…
Hello support team,
I want to clarify total delay of ADAU1977 and AD1934 (at fs=48kHz) .Group delay is specified in each datasheet as 22.9844/fs and 25/fs respectively, but how many extra sampling clocks do I need to assume for "Serial Auto Port" portion…
