Figure 6. MAX9225/MAX9226 Power-Up/Power-Down Sequence
Interconnect for LCDS typically has a differential imped-
ance of 100Ω. Use interconnect and connectors that have
matched differential impedance to minimize impedance
discontinuities.
Separate the LVTTL/LVCMOS and LCDS signals to pre-
vent crosstalk. A PCB or flex with separate layers for
power, ground, and signals is recommended.
Bypass each V
surface-mount ceramic 0.1µF and 0.01µF capacitors in
parallel as close to the device as possible, with the
smallest value capacitor closest to the supply pin.
The MAX9225/MAX9226 are rated for ±15kV ESD
protection using the Human Body Model. The Human
Body Model discharge components are C
