Hi Henry Here is feedback below Eagle (T99X171.00) 2nd source Hynix new die and switch tact list_0319.xlsx (10,019,150 bytes) 1. Please attache the Die Revision Notification from Hynix (PCN). 2. EMC/EMI Test can not waive the test report for Hynix DDR. Die change (revision) is related safety regulation - KC certification. 3. PCB "Change the PCB label to laser printing. : Please make the PCN letter by FII or PCB vender. Eagle (T99X171.00) 2nd source Samsung new die and Transformer list_0319_.xlsx (13,974,288 bytes) 1. Please attache the Die Revision Notification from Samsung (PCN). 2. Samsung DDR SI test report : Please update officially released report. 3. EMC/EMI Test can not waive the test report for Samsung DDR Die change (revision) is related safety regulation - KC certification. 4. Ethernet SI test report zip file - Lan 1G Ethernet pair4_pin7-pin8_D.pdf is broken. 5. Please update surge test report from vender. 6. EMC/EMI Test for Transformer : Please make EMI report before change Transformer (BOTHHAND) and after change Transformer(MINGTEK) if you have any question, please contact me. Thanks SON |

Hi SH, We booked the time slot with EMC lab in next week and expect to reply with a complete report according to the request above by 4/30. However, still have some questions 1. Surge test: a. We checked with vendor and they don't do the surge test for the transformer. They only do the Hi Pot test. b. Eagle is the product for indoor use...we don't quite understand why the request for surge test. Besides, the KC didn't request for surge test. Plz help check if this test could be waived. 2. PCN for PCB: As explained this is for manufacturing improvement...no PCN letter for it. Could you help explain this way? Thanks, Henry |

Hi Henrt 1. Surge test : if can not vender test, Please proceed Fii lab test even if not a part of KC and indoor use, this is SKB engineer request that verify surge test. the original Eagle ethernet with the transformer was verified surge test. Because part change requested by FII, FII have to prove surge no problem. 2. PCN for PCB : As I mentioned, PCN is the evidence for the change. Thanks SON |

Hi SH, Update report note : 1. Surge test : testing in progress. 2. Can the 2nd source parts that have been reported be issued EC ( release EC change) ? |

Hi Lonnie, Attached is EMC test report of Eagle 2nd parts Regards, Cooper |
|
|
Hi Lonnie, These are the test reports of the 2nd parts(eFuse, LDO, IR receiver, X'tal) Tact switch is still under testing, I will upload on here after testing finished. Regards. Cooper |

Hi Cooper Please check the contents below and give feedback. 1. X_tal - Y801’s drive level has tight margin. Please check orignal source’s drive level 2. E-Fuse - OVC waveform: Please wide time scale and capture as like orignal source(page1-2) - Please capture waveform same voltage and time scale about original and 2’nd source.(page 4-5) 3. LDO - Please capture waveform same voltage and time scale about original and 2’nd source.(page 5-7) - Please provide OVP/OCP/OTP test result if they support functions.

Hi Jung, The following is our reply, please help give feedback too 1. X_tal - Y801’s drive level has tight margin. Please check orignal source’s drive level [Cooper]: Please see the attached for our explain 2. E-Fuse - OVC waveform: Please wide time scale and capture as like orignal source(page1-2) [Cooper]: I'm not understand for your mean, You mean to ask our 2nd source vendor to provide the attached picture(please see attached) of page 1? - Please capture waveform same voltage and time scale about original and 2’nd source.(page 4-5) [Cooper]: Please point your concern about 2nd source's waveforms for us, we think that the 2nd's waveforms of voltage scale is not impact the test result, and the time scale is more accurate than original source. 3. LDO - Please capture waveform same voltage and time scale about original and 2’nd source.(page 5-7) [Cooper]: There still has more margin and results are pass too, please point your concern about 2nd source's waveforms for us. - Please provide OVP/OCP/OTP test result if they support functions. [Cooper]: 2nd source's LDO has no support OVP/OCP/OTP function in datasheet. Regards. Cooper Crystal explaination for Q1.png (90,878 bytes) Page 1 attached .PNG (16,625 bytes) |
