器件型号：TMDS181

您好！

我们将 TMDS181评估为灌电流。

我们尝试脉冲并拔下信号电缆、然后 TMDS181输出无效信号。

它会发生20次。

以下是我们的设置和条件。

信号源= 1920x1080@60Hz (来自信号发生器)。

MISC_CONTRAL_09H = 0x06
MISC_CONTRAL_0AH = 0xb1
MISC_CONTRAL_0Bh = 0x00
MISC_CONTRAL_0Ch = 0x61

我们不会向 Apply_RxTx_Changes 写入"1"、因为我们不会在 pulg 和 unplug 之间更改寄存器值。

可以告诉我任何建议或意见吗？

谢谢你

    您好！

    当寄存器0x09设置为0x02时是否会发生此问题？  

    您可以共享您的原理图吗？

    您可以在通过的案例和失败的案例之间转储第0页和第1页寄存器吗？ 要访问第1页、请将0x01写入寄存器0xFF、然后从寄存器0x00转储到0xB1。

    谢谢

    您好！

    >将寄存器0x09设置为0x02时是否会发生此问题？

    我们尝试 了上述设置、 TMDS181 目前工作正常。  

    我们将尝试更多的测试。

    但是、我想知道根本原因是什么、因此我将发送您要求的转储文件。

    我想  通过离线支持联系 以发送电路图。 没关系吗？

    转储数据将会非常低。 抱歉、我的单词太长、无法正确地附加转储文件。

    您好！

    请接受我的友谊请求、然后您可以将原理图发送给我进行审核。  

    我将寄存器0x09设置为0x02、这将保持 TMDS181循环通电、并在每次拔下/插入电缆时重新锁定输入数据。

    谢谢
