Framework 筆電也遇到缺料問題,換了音源晶片

Framework 的筆電最近在社群很紅,模組化設計讓維修變容易,而且也有許多規格上的客製化空間。在「Marketplace」這頁可以看到很多東西可以換,除了比較常見的無線網卡、SSD、記憶體以外,像是主機板、鍵盤甚至連 USB、HDMI 接口都是模組。

不過這邊要提到的是 audio chip 也在這波 supply chain 的供貨問題而中招了:「Solving for Silicon Shortages」,Hacker News 上的討論「Framework: Solving for Silicon Shortages (frame.work)」也可以看一下。

從文章裡看起來是 Realtek ALC295 的交期爆炸了:

Chips that would normally have 16-20 week lead times (meaning we’d place typically binding orders that far ahead of needing parts in our hands) went up to 52 weeks. In one case, we even got notified of a 68 week lead time on a chip!

We were able to get enough Realtek ALC295 audio CODECs to develop the Framework Laptop and get through the first few months of production, but nowhere near enough to fulfill ongoing demand from the US and Canada, let alone the additional countries we’d like to ship to.

所以決定換到 Tempo 92HD95B

Luckily, we were able to find an alternative CODEC that lets us stay in production: the Tempo 92HD95B.

查了一下 datasheet,本來的 Realtek ALC295 是 QFN-48,而 Tempo 92HD95B 是 QFN-40,看起來得改不少東西... 應該是連 open market 上都翻不到而被迫換設計,跟我們家的情況也很像,看起來最近大家都哭到爆炸了 :o
