Effecth?? what kind of DSP chips

Hello, I assume that the chip here is ADAU1701. This circuit module card is mostly used in amplifier mixers and it has effects in it. However, it seems that the chip in the place I marked is AU1701. All the reviews led me here. Do you think this is correct?

I've done a couple designs with ADAU1701, and there are a couple things that make me think that's not it. The ADAU1701 datasheet calls out a 12.288MHz clock for 48kHz sampling, and that board calls out a 24MHz clock. Also ADAU1701 typically uses a BJT as part of its internal regulator to generate a 1.8V rail for the digital core.

And most importantly, ADAU1701 doesn't have enough internal memory to store effects, especially 199 of them, and typically uses either an EEPROM or a microcontroller configured to send I2C messages, basically pretending to be an EEPROM.

So I don't know for sure what it is, but I don't think it's an ADAU1701.

When I get very close to the chip, I see the word AD. Could it be an ADSP chip? But which code is an ADSP?

ADSP is another product line from Analog Devices, which would make me guess it uses the same SHARC architecture as the ADAU series.

If you can't figure out how to write an algorithm for FV-1, you're not going to like the development process for SHARC.

I solved some problems with the algorithms with fv-1, no problem, I was just curious about the chip.
