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 V
DD
/2. Refer to Figure 2 for High Speed, Differential Input structure.
