17### Changelog
18
19#### 20210513_120hpf - PB6.47.0
20
21- Recharacterized and retuned with EVT Bucks
22  - **Top**: 5 samples (3 new ones + 2 from 20210323)
23  - **Bottom**: Same 3 samples as 20210323
24- Updated ReDC fallback per customer request.
25  - **Top**: 5.471 Ohms
26  - **Bottom**: 6.383 Ohms
27- Cal and Cal+Diag bin versions remain unchanged from 20210323 as these parameters have not been modified.
28
29#### 20210329_120hpf - PB6.47.0
30
31- Top speaker incorrectly had hpf as 150hz. Corrected fcutoff parameter on top speaker protect tunes.
32  - All other files same as _20210323 - PB6.47.0_
33- Renamed package and protect tune naming convention to match accompanying 20210329_150hpf tune package.
34
35#### 20210323 - PB6.47.0
36
37- Recharacterized and retuned with EVT Bucks (3 samples each Buck)
38  - Bottom Speaker
39    - **xmax**: 0.4mm
40    - **tmax**: 120C
41    - **hpf**: 120Hz
42  - Top Speaker
43    - **xmax**: 0.45mm
44    - **tmax**: 130C
45    - **hpf**: 120Hz
46- Updates to firmware from 6.45.0 to 6.47.0
47  - Implemented a timeout feature that allows a maximum delay between the start of the BCLK and the start of the LRCLK. If the timeout is exceeded, an error notification is sent to the driver and the command is ignored. This addresses a host-side timing issue for these signals that could lead to a no-audio situation.
48  - Fixed an issue where repeated pause/resume commands could cause pops on the output.
49
50#### 20210319 - PB6.45.0
51
52- Lowered tmax and xmax limits per customer request
53  - Top Speaker
54    - **xmax**: 0.4mm -> 0.3mm
55    - **tmax**: 120C -> 110C
56    - **hpf**: 150Hz (Unchanged)
57  - Bottom Speaker
58    - **xmax**: 0.45mm -> 0.35mm
59    - **tmax**: 130C -> 120C
60    - **hpf**: 150Hz (Unchanged)
61
62#### 20210122 - PB6.45.0
63
64- Recompiled 20201221 tune for PB 6.45.0. No changes to tune.
