The analog section of a Bluetooth audio SoC is where careful design pays off. Notes from the JieLi AC695N/AC696N guide:

For the DAC outputs, they recommend reserving positions for small inductors (100nH, 120nH, 220nH, 330nH) to form filters that can suppress high-frequency noise, specifically called out as TDD noise from a nearby mobile phone during calls.

A critical layout rule: around the DAC circuit and its solder points, pour AGND (or no pour at all). Explicitly: Do not pour "digital GND" and keep the area away from it. This isolation is key to preventing digital switching noise from coupling into the analog audio paths.

A component difference: For electret microphone solutions, the AC695N requires a DC blocking capacitor on the MIC input, which the AC696N does not. Important for BOM and schematic checking.

Simple, actionable advice for clearer audio.

For the and crowd: a concise summary of the hardware design guide for JieLi AC695N/AC696N Bluetooth audio SoCs.

It offers crucial DFM advice: you MUST provide test points for the programming pins (USB, power), as the small QFN package necessitates programming after SMT assembly via a USB connection.

For the #electronics and #embedded crowd: a concise summary of the hardware design guide for JieLi AC695N/AC696N Bluetooth audio SoCs.

It clearly states the non-negotiable absolutes: input voltage maxima (VBAT 5V, LDO_IN 5.5V), and the necessity of battery protection circuits.

It highlights the most critical component: the 24MHz crystal oscillator, specifying ±10ppm tolerance and 12pF load capacitance for reliable Bluetooth RF performance.

It provides a pragmatic power design choice: use the internal LDO if you can, or a >2MHz external DCDC converter (with 1% feedback resistors) for the 1.26V core if you need the efficiency.

Finally, it offers crucial DFM advice: you MUST provide test points for the programming pins (USB, power), as the small QFN package necessitates programming after SMT assembly via a USB connection.

Ever wondered about the tech behind your Bluetooth headphones' sound quality?

We've come a long way from the basic SBC. Now we have a range of options like Apple's preferred AAC, Qualcomm's aptX family (including Lossless!), Sony's high-bitrate LDAC, and the efficient new LC3 codec for LE Audio.

The future of wireless audio is bright and increasingly high-fidelity.

Ever wondered about the tech behind your Bluetooth headphones' sound quality? My latest blog post is a deep dive into the world of Bluetooth audio codecs.

We've come a long way from the basic SBC. Now we have a range of options like Apple's preferred AAC, Qualcomm's aptX family (including Lossless!), Sony's high-bitrate LDAC, and the efficient new LC3 codec for LE Audio. The post explains the crucial roles of bitrate, sampling rate, and the underlying hardware chipsets that make it all possible. It's not just about the codec support; it's about the entire chain.

The future of wireless audio is bright and increasingly high-fidelity. Are you ready for lossless over Bluetooth?

Has anyone ever made 'Bluetooth relays', and are they even possible?
I wanna be able to extend the bluetooth range of my desktop through my entire apartment, is there any way to make a kind of mesh network of bluetooth repeaters/relays like there is with wifi?

Oh lago mio. auf ist einfach Schrott. Super frickelig-empfindlich und instabil in urbanen Gebieten.

Beanstanden Leute das, wird wieder dogma-gelabert, dass sich Linux ja ganz brav an die Specs hielte und andere ja nicht und deshalb.

Fuck off. Eine Eisenbahnstrecke wird auch gebaut, wenn ein See im Weg ist.

"perfect policy"-Ausrede, ein Klassiker unter Klimaleugnern und hundert LY entfernt von pragmatischer Lösungsfindung.

Manchmal nervt mich das so unendlich.

Was recommended the Soundcore Liberty 3 Pro so thought I’d purchase and test.

Initial Findings:

Fit/Comfort is great
Plenty of options for wings/ear tips to suit most ears
Setup was easy

I like HeardID which analyses the ears based on age/sound can hear best & adjusts the sound profile to suit you, seriously impressed how well it’s done.

You don’t have to spend silly money to get a good pair of earbud.
