Help identify "B0RC1" component on USB-to-I2S audio adapter

[13hm13]

Have a look at this image....


There are three identical black-rectangle devices with "B0RC1" or "BORC1".
Can't find any info about them. However, a very similar device leads one to believe the devices are oscillators:



Any info on the "B0RC1" or "BORC1" device is appreciated.

NOTE: A very  similar USB adapter I personally own has devices labelled B0RC7, not B0RC1. So mine end in "7", not "1". Very strange ... maybe fake labeling to prevent reverse engineering attempts?

P.S. The ebay/Ali listing hints the devices may be " SITIME silicon crystal oscillator ". ??

The hint is correct; does this look familiar?

The SIT 8008 datasheet reveals that the markings are just an assembly location and lot number, so no doubt they will vary.

Thanks!
I'm wondering why SiTime chose to use that cryptic labeling strategy? Is it deliberate obfuscation for (as I noted earlier) hindering reverse engineering?
