Board Layout
Separate the LVTTL/LVCMOS inputs and LVDS output to
prevent crosstalk. A four-layer PC board with separate
layers for power, ground, and signals is recommended.
ESD Protection
The MAX9217 ESD tolerance is rated for Human Body
Model and ISO 10605. ISO 10605 specifies ESD toler-
ance for electronic systems. The Human Body Model
discharge components are C
S = 100pF and R D =
1.5k Ω (Figure 14). The ISO 10605 discharge compo-
nents are C S = 330pF and R D = 2k
Ω (Figure 15).
