嗨，
我可以在某处找到Artix7 GTP收发器功耗的信息吗？ 我知道MGTAVVT和MGTAVCC必须来自单独的LDO，但每个LDO需要多少电流？ 我们计划使用XC7A200T-2FBG484I，我们只使用4个GTP中的3个。 现在我有MGTAVCC的1 LDO@1.2安培和MGTAVTT的1 LDO@1.2安培。 你认为是否足够或我必须增加更多的力量？ 我看了ds180,181和ug482，但我找不到任何东西。 我错过了吗？ 问候， 帕诺斯 以上来自于谷歌翻译 以下为原文 Hi, can I find somewhere the information of the power consumption of the Artix7 GTP transceivers? I know that MGTAVVT and MGTAVCC must be from seperate LDOs but how much current do we need for each one? We are planning to use the XC7A200T-2FBG484I and we will use only the 3 of 4 GTPs. Now I have1 LDO@1.2Amps for the MGTAVCC and 1 LDO@1.2Amps for the MGTAVTT. Do you think is enough or I have to add more power? I looked at ds180, 181 and ug482 but I couln't find anything. Did I missed it? Regards, Panos

您应该能够使用XPE电子表格找到电源要求。

嗨，
根据DS181 Pg6，UG482（接通电源和去耦电容）后面的Pg 232以及上电/断电序列应该有助于确定电源。 http://www.xilinx.com/support/documentation/user_guides/ug482_7Series_GTP_Transceivers.pdf http://www.xilinx.com/support/documentation/data_sheets/ds181_Artix_7_Data_Sheet.pdf 同时让我检查一下我们是否有GTP的最低电流要求。 谢谢，AnirudhPS：请将此标记作为答案，以防它有助于解决您的问题。如果帖子引导您找到解决方案，请给予赞誉。 以上来自于谷歌翻译 以下为原文 Hi, Pg 232 onwards of UG482(On power supply and decoupling capacitors) and following the power up/down sequence as per DS181 Pg6 should be helpful in deciding your power supply. http://www.xilinx.com/support/documentation/user_guides/ug482_7Series_GTP_Transceivers.pdf http://www.xilinx.com/support/documentation/data_sheets/ds181_Artix_7_Data_Sheet.pdf Meanwhile let me check if we have the minimum current requirements for the GTP's. Thanks, Anirudh PS: Please MARK this as an answer in case it helped resolve your query.Give kudos in case the post guided you to a solution. |

嗨，
如果你能提供这些信息，那就太好了。 您是否还拥有足够功能所需的最大电流（MGTAVVT和MGTAVCC）？ 先谢谢你， 帕诺斯 以上来自于谷歌翻译 以下为原文 Hi, if you can provide me with this info it would be great. Do you have also the maximum current (MGTAVVT & MGTAVCC) that is needed for sufficient functionality? Thank you in advance, Panos |

功耗取决于设计。
如果在XPE中输入与设计密切匹配的详细信息，则可以获得功率编号。 如果您参考AC701威廉希尔官方网站 板原理图，您可以找到功率调节器详细信息的示例。 -------------------------------------------------- ----------------------------别忘了回复，给予kudo并接受为解决方案--------- -------------------------------------------------- ------------------- 以上来自于谷歌翻译 以下为原文 The power consumption is design dependant. If you enter the details in XPE to closely match the design, the power numbers can be obtained. If you refer to AC701 board schematic, you can find an example of power regulator details.------------------------------------------------------------------------------ Don't forget to reply, give kudo and accept as solution ------------------------------------------------------------------------------ |

哎呀，
我先发布消息，但我没有看到你的消息。 非常感谢，我认为这是正确的工具:-) 问候， 帕诺斯 以上来自于谷歌翻译 以下为原文 Oops, I post my message first and I didn't see yours. Thanks a lot, I think it's the right tool :-) Regards, Panos |

嗨，
最后一个问题。 我用功率估算器计算GTP功耗（见附件），总电流（wosrt情况）为MGTAVcc = 0.373A，MGTAVTT = 0.260A。 问题是：对于具有双GTP的AC701，为什么它使用3Amps用于MGTAVcc和3Amps MGTAVTT，因为每个均为1安培绰绰有余？ 我错过了什么吗？ 先谢谢你， 帕诺斯 以上来自于谷歌翻译 以下为原文 Hi, one last question. I calculate the GTP power consumption with power estimator (see attached) and the total current (wosrt case) is MGTAVcc = 0.373A and for MGTAVTT = 0.260A. The question is : for the AC701 which has the double GTPs why it is used 3Amps for MGTAVcc and 3Amps MGTAVTT as even 1 Amp for each is more than enough? Am I missing something? Thank you in advance, Panos |

评估板通常使用高功率电源，因为它们的设计早于器件可以投入生产。
因此，所采取的利润会更多。 -------------------------------------------------- ----------------------------别忘了回复，给予kudo并接受为解决方案--------- -------------------------------------------------- ------------------- 以上来自于谷歌翻译 以下为原文 Evaluation boards generally use high wattage supplies since they would be designed earlier than the device could go to production. So the margin taken would be more.------------------------------------------------------------------------------ Don't forget to reply, give kudo and accept as solution ------------------------------------------------------------------------------ |
