Input Structures
Two input structures exist 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 3 for High Speed, Differential Input structure.
Figure 3: High Speed, Differential Inputs (L_SIn/IN)
Because the VSC7122 output buffers are PECL outputs referenced to V
DD
, the High Speed Differential out-
puts may not be direct coupled to the high speed differential inputs. One example of how to differentially cas-
cade the two VSC7122 is shown in Figure 4.
