相信很多玩家在看一块主板的介绍资料或者测试文章时,总会看到1394控制芯片的说法,最常见的就是我们熟悉的VT6307控制芯片,可有的主板上却会同时出现两颗1394控制芯片,这是怎么回事? 实际上,1394功能的实现有两个环节:物理层和链路层,在现在的主板芯片组中,还没有哪一款是直接在芯片组内部对二者都能支持的。这都需要外挂芯片来解决,我们大家熟悉的VT6307是一颗整合了物理层和链路层的二合一芯片,所以我们在主板上只看到一颗芯片是很正常的,而象技嘉K8NNXP主板上有两颗TI(德州仪器)出品的1394控制芯片,其实不用奇怪,这只是把物理层和链路层分开控制造成的。
I believe many players see a piece of motherboard introductory information or test articles, you will always see the 1394 control chip, the most common is that we are familiar with the VT6307 control chip, but some may appear on the motherboard while two 1394 control chip , What’s going on? In fact, 1394 functions are implemented in two aspects: the physical layer and the link layer, and in the current motherboard chipset, no one is directly inside the chipset for both Supported. This requires a plug-in chip to solve, we are familiar VT6307 is a combination of the physical layer and the link layer combo chip, so we only see a chip on the motherboard is normal, and as Gigabyte K8NNXP There are two TI (Texas Instruments) produced 1394 control chip on the motherboard, in fact, not surprising, this is only caused by the physical layer and the link layer separately.
