I'm looking to buy a cheap Aliexpress/eBay ADAU1452 board to learn more about the Analog family of DSPs.
As usual, browsing the seller's description, there is some weirdness that hopefully can be explained by a game of telephone in multiple languages resulting in actual information loss.
One of the puzzling pieces is that in some of those descriptions, the ADAU1542 seems to only support 96KHz SPDIF, and only the ADAU1466 supports 192KHz. That is contrary to all the datasheet info I could find.According to this post ez.analog.com/.../adau1462-150-pll-and-other-settings, any difference is hidden from the user, and SigmaStudio doesn't have a 1452-150 part
I noticed, though, that there is a half-clock version of the ADAU1542, the ADAU1452WBCPZ150. How would I recognize if the chip on those boards is the full speed or half-speed version, from the markings on the chip? The datasheet doesn't show the SMD chip markings (unlike most datasheets), so it's hard to know what to look for
Is the chip below a 294.912 MHz part or the slower 147.456 MHz part?
