走向超值而極緻的 HI-FI電腦訊源（連載）

Seeteeyou兄謝啦，

ISOUSB211 是個巨大收獲，我在淘寶上買到了。

它居然有各種黑科技是同類產品絕對辦不到的，其中一項就是可編程均衡。

它會主動補償傳輸過程中的損耗，重新「捏出」一個方正、乾淨的訊號波形傳給 DDC。
這太誇張了，值得試試看。

SiO2 電容隔離： 這是 TI 的專利技術，利用二氧化矽作為介電質。它的優點是反應極快（降低 Jitter）、抗干擾能力超強（CMTI 高達 100kV/μs），且自身輻射極低，不會干擾到旁邊敏感的類比電路。

這個也很扯。

至於DDC不用擔心啦，套件有多輸入，我直接上面切換就好，可以不用透過樹莓派。

gangster.tank 兄不用客氣。

目前已經有好幾款同樣具備 USBISO211 的產品，但是價格與效果這兩方面並沒有明確的關係：

Could this be an alternative?

Could be, but I think the Jhoinrch has accumulated sufficient rave reviews that it stands above others. Some of us have tried alternatives like the Altor and LHY UIP (without external clock) and still the Jhoinrch wins. I think they've got the ancillary isolating power topology spot on.

It's a punt in the dark so let us know if you try it. The $37 Jhoinrch delivers, for sure.

l think the Jhoinrch improvements are in its component choice,and it's 5v regulator lsolation module, it looks sheilded, and more compact, in theory there should be no differences between the Altor Audio and Jhoinrch,as they use the same chip,and yet the Jhoinrch is in a different league.

那個 Altor 的品牌於 2024 年的時候已經出現了，但是不知道是否受制於晶片批次的問題，亦有可能是因為它的設計比較遜色，故此並非那麼吃香的說：

I have one of these en route, the ISOUSB211 version, with DC power input. I seem to be collecting USB isolators of all stripes.

Other than above, TI may have a quality problem. If you recall delay of general availability, it can be some inferior quality batches or just a bad pre-production samples leaked to the public. I suggest to post a hires photo of the chip. It would help to identify a bad batch.

Jhoinrch RH-07B 於 2025 年 10 月 24 日才上市，或許最近期的晶片質素比較好一點？當然 USB 公頭的直插式設計也不容忽視，signal integrity 方面比較佔優。

另外 5V 電供與及線材亦舉足輕重，前者當然是價格不菲的 IanCanada，後者就應該是 Elecom 比較強，但是轉接頭方面也是比較頭痛的說：
