Created the two requested Phase 2 control documents and made no schematic/layout changes.
Files:
Open items:
- The ERS now supersedes earlier informal briefs where conflicts exist.
- PCB placement/routing should wait until the Phase 2 engineering reviews are complete.
Suggested next steps:
- Produce the Engineering Review Report.
- Build the component comparison matrix.
- Create the power-state diagram and updated runtime estimates.
- Generate the prioritized schematic change list.
how do i save those specs/plans files to my device?

Prototype Revision A Verification Notes — Munkrofon
Status
Prototype Revision A — Not Production Validated
This file summarizes what was built, what the automated checks found, and what still blocks production readiness.
Schematic Built
The schematic now contains an exploratory two-unit wireless microphone prototype:
Transmitter
- RTX1090R1 provisional DECT RF module block.
- TLV320AIC3204 codec block.
- THAT1580 balanced low-noise microphone preamp.
- Female XLR input.
- USB-C charging input.
- BQ24074 charger / power-path IC.
- AP2112K 3.3 V LDO.
- MAX17048 fuel gauge.
- TPS65131 ±5 V analog rails for the THAT1580.
- Provisional antenna placeholder components for ANT1/ANT2.
Receiver
- RTX1090R1 provisional DECT RF module block.
- TLV320AIC3204 codec block.
- THAT1646 true balanced line driver.
- Male XLR output.
- USB-C charging input.
- BQ24074 charger / power-path IC.
- AP2112K 3.3 V LDO.
- MAX17048 fuel gauge.
- TPS65131 ±5 V analog rails for the THAT1646.
- Provisional antenna placeholder components for ANT1/ANT2.
Important Rev A Assumptions
Table
| Area | Assumption | Why it is provisional |
|---|---|---|
| RTX1090R1 footprint | Created from public datasheet pin table and LGA geometry. | Official RTX CAD footprint/reference layout not available. |
| RF audio interface | TLV320AIC3204 digital-audio/control pins mapped to plausible RTX1090 GPIO/audio-capable pins. | Public RTX datasheet confirms digital audio capability but does not publish exact Sheerlink codec pin mapping. |
| Antennas | NN02-224 wideband chip antenna placeholders used only to make antenna nets explicit. | Official RTX1x90EVK antenna geometry, matching, spacing, diversity orientation, and modular-approval conditions are still required. |
| USB data | USB-C D+/D− are protected by ESD devices but intentionally unused for Rev A charging-only USB. | Final RTX firmware may require USB for programming, control, or test. |
| Fuel gauge | MAX17048 I²C tied to the provisional codec/control bus. | Final host/firmware ownership of battery gauge is unknown. |
| Analog rails | ±5 V rails added for THAT1580 and THAT1646 after datasheet review showed dual supplies are required. | Final audio headroom may require different analog rails. |
Automated Check Results
After wiring fixes:
- Floating-pin errors: cleared, except no current floating-pin findings in the final queried set.
- Single-pin antenna-net errors: cleared by adding antenna placeholder components.
- Remaining ERC category: Missing Power.
Remaining Missing-Power Findings
The remaining errors are treated as Rev A review items rather than silently ignored:
Table
| Finding class | Affected examples | Interpretation |
|---|---|---|
| System rails not recognized as driven | U5 VIN, U13 VIN, U11 VIN, U14 VIN, U1/U7 VBAT | Rails are fed by BQ24074 OUT / battery path, but ERC does not treat that path as a formal power source in this schematic. Review during bring-up. |
| Codec internal-LDO output rails | U2/U8 AVDD and DVDD on codec LDO-output/filter nets | TLV320AIC3204 uses internal LDO/filter pins; ERC flags them because it does not understand the internal regulator. Confirm against TI power-sequencing app note before layout. |
| RTX module output pins | U1/U7 VDD_1V8, VDD_3V3, VDD_USB, VSUPPLY | Public RTX datasheet labels these as module outputs or optional supplies, but the provisional part/checker reports them as power inputs. Requires official RTX guidance. |
| THAT1646 VCC driven by RX_5VA | U9 VCC | RX_5VA is generated by TPS65131, but ERC does not recognize the generated rail as driven. Verify with power-stage simulation/bring-up. |
Production-Readiness Dependencies
Before this can become production-intent:
- Official RTX1090/R1 hardware integration guide.
- Official RTX/RMED Sheerlink reference schematic, PCB layout, Gerbers, stackup, and BOM.
- Official antenna layout/matching/diversity requirements and modular-approval conditions.
- Exact Sheerlink audio pin mapping, clocking, codec support list, and firmware configuration.
- Written latency specification for the selected configuration.
- Confirmation of RTX1090 VDD/VBUS/VBAT ownership and whether external charger + module power pins are valid as drawn.
- Prototype measurement of analog rail ripple/noise and effect on mic preamp / line output noise floor.
- Audio performance verification: gain, clipping headroom, THD+N, SNR, noise floor, frequency response.
- RF range/coexistence testing and EMC pre-scan.
- Final PCB layout review against RTX reference design.
