@Henry Please check if you can provide samples below connectors. We will prepare 60 sets for materials. - Speaker connector 4pin: S4B-EH(LF)(SN) * 2pcs /1board -> Total 120 pcs + 20 pcs (spare) - Amp board Power connector (2Pin): 51318-0023L-001 * 1pcs /1board -> Total 60 pcs + 10 pcs (spare) - FFC connector (10Pin): correct pin count are 15pin: FH41-15S-0.5SH(05) * 1pcs /1board -> Total 60 pcs + 10 pcs (spare) So, please check quickly. Let us know if it can be free sample or paid sample. Thanks SON |
|
|
Hi SH, As you know we cannot sell materials...so I will check with vendor if they could support samples and reply by 2/22. Thanks Henry |
|
|
@Henry One more request. in Korea, the power common filter as used DVT amp board, can not search this item. power common filter (BPPM00090770152X0F)* 1pcs /1board -> Total 60 pcs + 10 pcs (spare) Please let me know if you can send it with other materials Thanks SON |
|
|
Hi SH, I have got 2 vendors' reply on the 1st request that they can support the samples. Except 51318-0023L-001 is still under checking with vendor... I will check the new request and get back to you together later. |

Hi, Sean I updated SWAN Amp board schematic and BOM. Please let me know if you have further questions. Best regards Lonnie Kim |
|
|
Hi Lonnie, After checking your AMP board design and internal discussion with SW team, we have some questions from SW point of view. 1. Is it a standalone system and will be run with an embedded Linux OS ? 2. We knew I2S interface will be used as sending audio data and how to control and communicate between VS550 and A113X ex: volume control, EQ enable/disable? Will it be controlled by VS550 or A113X via I2C interface ? 3. Which SoC(OS) do initialize AMP device via I2C bus? 4. How to update F/W in NAND flash of AMP board through VS550 ? |
|
|
Hi River, Per talked, please provide your question list here from VS-550 host side (Android TV) and we have to understand which SW modules we need to modify in F/W of Android TV. |
|
|
Dear Mr. Yoon The attached file includes the question list (including above mentioned SW questions) and the R&R draft which will be continuously updated after we learn more details from ALT. The first priority should be the schedule sharing for Fii to better understand ALT's plan of following development so that we know how to act promptly to make the design change go smoothly, e.g. we are not sure when we should finish the BOM and the schematic review and feedback. Plz help check the available time slot for discussion over question list. Thanks Henry |
|
|
Hi Henry Chiou reply 0001143:0006152 Here is the answer about your question list. and also please update HW section. I think HW engineer has many question about new amp design. Thanks SON |
|
|
Hi, SH 1. Why reserve USB signal on 15 pin FFC cable? 2. I think the purpose of J202 is for debugging AMP IC, when A113x software is not ready. Current design AMP IC, A113x and J202 connected together. Could you reserve 0ohm resisters on pin H16, G17, G16 and G14? So that, we can disconnect A113x and J202 during debug. 3. If each AMP IC have its own EQ. I suggest that add resistors at I2C bus of each AMP IC. 4. Could use Fii vendor for below components? eMMC Flash, vendor: Samsung, Hynix, Sandisk J202: connector, vendor: FIT, ACES Power inductor, vendor: CHILISIN, Maglayer DC/DC power IC, vendor: MPS, TI LDO, vendor: TI, Fiti power, Thanks ! |
|
|
Hi, SH For item4, I attached the list for you reference. Thanks ! |
|
|
Hi, Tom Please refer to below my comments 1. Why reserve USB signal on 15 pin FFC cable? --> [ALT]USB signal will use S/W download path. We will provide detail explain within next week. 2. I think the purpose of J202 is for debugging AMP IC, when A113x software is not ready. Current design AMP IC, A113x and J202 connected together. Could you reserve 0ohm resisters on pin H16, G17, G16 and G14? So that, we can disconnect A113x and J202 during debug. -->[ALT]Okay, we will ready 0ohm. 3. If each AMP IC have its own EQ. I suggest that add resistors at I2C bus of each AMP IC. -->[ALT]Yes, it can use I2C for EQ setting. 4. Could use Fii vendor for below components? eMMC Flash, vendor: Samsung, Hynix, Sandisk --> [ALT]Refered from QVL, can use Skyhigh, Kingstone, Toshiba. J202: connector, vendor: FIT, ACES -->[ALT]It will delete at mass production. Power inductor, vendor: CHILISIN, Maglayer --> [ALT]You can change. DC/DC power IC, vendor: MPS, TI --> [ALT]Amlogic reference is Silergy. I think you used silergy at Eagle and SWAN, so you can use them. TMI SUNTO is same with Silergy parts. LDO, vendor: TI, Fiti power --> [ALT]Amlogic reference is Will semi. So, you can choose similar parts. Best regards Lonnie Kim |

Hi Sean Here is new Amp board 3d modeling data draft version. this 3d data worked on so far. Major structure want to fixed at this time - screw hole, Major component location (IC, Inductor, Cap...) but It may need to minor update (fine running) Please check below 1. with heat spreader - Screw point with SoC top heat spreader / Amp Top heat spreader - Thermal pad boss ready on Amp Bottom heat spreader : each amp IC (4PCS) 2. assembly check (DFM) Thanks SON amp.png (33,999 bytes) |
|
|
Hi SH, Got it. We will check the position of screw hole and major components first. Jim will review that and let you know if there is any further questions. Thanks! Regards, Sean |
|

Hi SH, From the "SWAN design change Discussion_210226_ALT.xlsx", your answer for the following question is as below: [Question] Which SoC(OS) do initialize AMP device via I2C bus? >>>[ALT] A113x (Linux) will initialize AMP device WA20-6829B (wellang) Then you will need to integrate the AMP drivers by A113x. Please also sync with your Hardware that the I2C A16/B15 pin of A113x can be used for this purpose (As an I2C master). Please also note , there is a request from SKB that the NUGU Call needs to disable EQ/DRC to have better voice quality. You can see the this request at mantis https://172.18.223.170/vaas/view.php?id=992 You can ask Wooshin, he knows this request. So, if you integrate the AMP drivers by A113x, you will need to provide a way to let VS-550 can communicate with A113x to disable/enable EQ/DRC. NUGU Call will need a API to do it. What is interface you will provide for VS-550 to send command to A113x and can get response from A113x? |

|
|
Hi Lonnie, Could you please provide the DSN schematic and brd file(board file) of allegro for our layout team? If our layout team has these files, they can work easy for sub board processing. Thank you. |
|
|
Hi, Fu-chiang Young I already provide Gerber file. What means sub board processing? Best regards Lonnie Kim |
|
|
HI Henry reply 0001143:0006575 before confirm ALT fedex account number, please check can ship together top housing of MIC sealing tested Thanks SON |
|
|
Hi Lonnie, Due to sub board panel includes LED board/MIC board/Side LED board/Button board/AMP board, we combine them all together for PCB vendor and for SMT. Before to PCB and SMT, we need do many process such as schematic netlist generated then generate new gerber file with all sub board. So it is so complicated and layout team needs completed files to work which we call sub board process. So allegro DSN file is for schematic to generate netlist file, and brd file is for layout into one pcb panel. Could the files can provide to us? We can have better process to SMT. Thank you. |
|
|
Hi SH reply 0001143:0006583 The top case is ready to ship with common mode filter. Plz confirm the FEDEX. Thanks Henry |
|
|
Hi, Fu-chiang Young I can provide netlist file, but I don't understand why need to brd file? Best regards Lonnie Kim |
|
|
Hi Henry reply 0001143:0006588 Ok. Confirm the use ALT fedex account 8528-5133-3 Please ship the top case with common mode filter. Thanks SON |
|
|
Hi Lonnie, When we generate netlist from DSN file, layout team will start to layout. It is normal case. But in this case, layout is done by ALT and we need brd file to conduct into gerber with other sub boards into one pcb panel. So that is why we need brd file. Thank you. |
|
|
Hi, Fu-chiang Young Please refer to brd file. Best regards Lonnie Kim |
|
|
Hi, Sean Please refer to Amp performance check result. Best regards Lonnie Kim |

Hi SH The common mode filter has been shipped out with top case with tracking no. 773371425022. Hi Lonnie About the substitute of ECAP CLZ35VC101MH10TP from SAMYOUNG, we checked with several vendors and got the reply no other projects using the same spec as high requested; thus they don't have stock on hand to fulfill our demand 840pcs for DVT3 with ETA 4/21 Would you plz help check if ALT could support the qty' for DVT3 and we will find the substitute for MP? Or we could downgrade the spec and check with vendor again? Thanks, Henry |
