The good news is that Mouser has 30000 of the Si5351A-B ordered.
Bad news:? They are scheduled to arrive Christmas week of 2021:

Digikey has 1123 in stock of the Si5351A-B04486-GT variant.

The datasheet addendum says they have an i2c address of 0x62, the standard part is at 0x60.
So change the firmware to try both, see which address responds.

If anybody wants to ship product with an Si5351, they should buy a few hundred.

Excellent excuse to roll the Raduino for a better processor.
We might even think about alternatives to the Si5351A-B.
This year should be a good opportunity to sell the uBitx.
All the other rigs with the fancy DSP chips will have a much harder time.
