SATA接口一致性,信号质量检测
SATA接口定义描述:
1、SATA数据接口定义:
1 GND Ground(接地,一般和负极相连)
2 A Transmit(数据发送正极信号接口)
3 A- Transmit(数据发送负极信号接口
4 GND Ground(接地,一般和负极相连)
5 B- Receive (数据接收负极信号接口) -
6 B Receive (数据接收正极信号接口)
7 GND Ground(接地,一般和负极相连)
2、电源接口定义:
01 V33 3.3v Power (直流3.3V正极电源针脚)
02 V33 3.3v Power (直流3.3V正极电源针脚)
03 V33 3.3v Power, Pre-charge, 2nd mate (直流3.3V正极电源针脚,预充电,与第二路配对)
04 Ground 1st Mate (接地,一般和负极相连,与第1路配对)
05 Ground 2nd Mate (接地,一般和负极相连,与第2路配对)
06 Ground 3rd Mate (接地,一般和负极相连,与第3路配对)
07 V5 5v Power, pre-charge, 2nd mate (直流5V正极电源针脚,预充电,与第二路配对)
08 V5 5v Power (直流5V正极电源针脚)
09 V5 5v Power (直流5V正极电源针脚)
10 Ground 2nd Mate (接地,一般和负极相连,与第2路配对)
11 Reserved – 保留的针脚
12 Ground 1st Mate (接地,一般和负极相连,与第1路配对)
13 V12 12v Power, Pre-charge, 2nd mate (直流12V正极电源针脚,预充电,与第二路配对)
14 V12 12v Power (直流12V正极电源针脚)
15 V12 12v Power (直流12V正极电源针脚)
PS:
(1) 3.3V不接是一样的正常使用,但有用不带3.3V的电源线接的SATA硬盘不认的情况。
(2)在2.5英寸的笔记本串口硬盘中,+12V脚(即后三脚)悬空。
在网上买到的SATA电源线,一般都是4线的,只有5V、12V、地:
