PCM5102, 2VRMS ground centered direct output with two digital filters

Eric Juaneda · 16th July 2011, 07:47 PM

TI announce the PCM5102 a DAC chip integrating two different digital filters, a direct path 2V RMS ground centered output.

PCM5102 Audio Stereo DAC (29 Apr 2011)

Datasheet: PCM5102

Few characteristics:
- Hardware control,
- Full scale output 2.1V RMS (Ground center),
- No DC blocking capacitor required,
- Sampling frequency 8KHz to 384kHz,
- Accepts 16, 24 and 32 bit audio data,
- Classical FIR Brickwall filter and Apodising IIR filter
- Integrated high-performance audio PLL to generate SCK internally

This chip seems ideal for simple DAC.

No the second one

I meant you were NOT the first.
Why not merge the two threads ?

ionutzxpo want help for its personal realization. It is not really an open thread to speak about PCM5102's interesting characteristics.

I have some doubts that many people were interested by a thread named 'PCM5102'. Except if they already knew this circuit.

Hi guys,I am a beginner in digital audio conversion and i don't know how to connect the PCM2707 to PCM 5102 to make a simple functional USB DAC with much much better performance than any other integrated sound solution (I use computer for music playback)

The PCM5102 upsample audio data to 352.8/384KHz.
- 44.1KHz, 88.2KHz, 176.4KHz are upsampled to 352.8KHz,
- 48KHz, 96KHz, 192KHz are upsampled to 384KHz.

i got my sample up and running last night. It's sort of similar (but better i think) to the wolfson WM8524 used in the GrubDAC.

It is a very easy DAC to implement and interface to. It needs very few components to make it work, and only needs a single 3.3V supply. I've only listened to it briefly so far. I'm thinking only a tiny PCB would be needed to piggyback onto my MiniDSP to replace the built-in DACs.

from reading the PCM5102 evaluation board datasheet, it seems that there may be a PCM5122 chip as well in the future, which has software control and digital volume control.
