这里主要为PCB板上电源插座以及板间连接器


高速连接器

FMC:英文全称,FPGA Mezzanine Card。专为FPGA高密度pin脚高速信号设计,其中connector图如下:

FMC (VITA 57.1)

High Pin Count (HPC) 400 I/O high-speed array system

Mechanically compatible Low Pin Count (LPC) 160 I/O can also be used with any of the form factors detailed in the standard  (Zedboard采用的就是这种接口)

FMC+ (VITA 57.4)

High Serial Pin Connector (HSPC) with 560 pins (provides 24 GT interfaces)

High Serial Pin Connector extension (HSPCe) with 80 pins (provides additional 8 GT interfaces; this connector is optional)

分为 FPGA Baseboard Side(female) 和  Mezzanine Card Side (male)

特点是比较贵!

标准连接器

插针 : terminal strips 和 socket strip,俗称排针和排母。间距2.54mm 2.0mm 1.27mm。
