Hex Port Bypass Circuit / Dual Repeater

for 1.0625 Gb/s FC-AL Disk Arrays

Input Structures

Two input structures exists in this part; TTL and High Speed, Differential Inputs. The TTL Inputs will inter-

face with any TTL or 3.3V or 5V CMOS outputs. The High Speed, Differential Inputs are intended to be AC

Coupled per the FC-PH specification. Being AC Coupled, the High Speed, Differential Input buffers are biased

at VDD/2. Refer to Figure 2 for High Speed, Differential Input structure.
