content: I've looked for a datasheet for this chip, but can't find anything. The RTL8213B is apparently a gigabit ethernet <-> fiber converter.So if anyone happens to know how to get ahold of it...

Or ask one of the Chinesian forum members for help, all of them have CSDN access. The chip is old enough that even Realtek doesn't admit that they ever produced it.Cheers,DC1MC

content: Yeah, saw those links already but they were not helpful. I actually got the RTL8211 and 8212 datasheets easily - but those are ethernet to GMII interface chips, basically. The 8213 specifically translates ethernet to 1000Base-X fiber.I dunno if this chip is that old. It doesn't appear on Realtek's website, and seems to be available only from brokers or Aliexpress and the like. But it's actually the basis of many gigabit ethernet-to-fiber converters, it's certainly still used quite a bit.

content: Found this, so far:https://oshwhub.com/Kirito/ji-yu-RTL8213Bde-qian-zhao-guangat the bottom of this webpage is a link to the datasheet but you need to enroll (free) to access it. It is worth the effort.

content: OK thanks. Apparently you need to give your phone number to register, I do not like this much. (But if there's another way...)I could find the first page of the DS so far, and the chip is not *old*. The DS is from 2018. The reason it's not publicly available is that it's marked confidential and clearly states that it's for Realtek's "development partners" only.https://dl-preview.csdnimg.cn/12929803/0001-48566101c6e280180c8c3ed673477ccb_thumbnail.jpeg

content: Try to activate with a virtual phone number like this one:https://quackr.io/temporary-numbers/china** As if NDAs mean anything in China.

content: here it isit does not explain the I2C register map anyway (which is what i wanted to know about).

content: Thanks. That's for RTL8212 and not RTL8213 though. They are quite different IC's, but I suppose they share a lot of the registers.
