C6678开发板连接器的问题FEMALE HEADER 2x40P 1.27mm 180D(F) SMD 22L8742

FEMALE HEADER 2x40P 1.27mm 180D(F) SMD 22L8742这个连接器的芯片资料没有找到呀，我要画电路板，和 H1的80针连接器相连接，我去百度和GOOGLE都没找到SMD 22L8742的资料，让我怎么画电路板呀

在TI E2E 论坛也有人问 FEMALE HEADER 2x40P 1.27mm 180D(F) SMD 22L8742的资料：

Thank you,  I'll look there and dig in, in more detail.

Meanwhile, I need to hook up the External 80pin Expansion bus to get diagnostic data output. 

The BOM for the C6678 EVM lists it as TEST_PH1 FEMALE HEADER 2x40P 1.27mm 180D(F) SMD 22L8742

I can't find a matching male connector on eg digikey.

Any idea where I can find a male header –ribbon-cable–male header  that will plug into this connector?

我的理解是只需要知道EVM上80pin header输出各个pin的信号，然后根据需要在画子卡时引出相应的信号接个插针，即可与EVM 80pin连接。
