ic interference (EMI) can either couple into or be gener-
ated by the MAX5187/MAX5190. Therefore, grounding
and power-supply decoupling guidelines for high-
speed, high-frequency applications should be closely
followed.
First, a multilayer PC board with separate ground and
power-supply planes is recommended. High-speed
signals should be run on controlled impedance lines
directly above the ground plane. Since the MAX5187/
MAX5190 have separate analog and digital ground
buses (AGND and DGND, respectively), the PC board
should also have separate analog and digital ground
sections with only one point connecting the two. Digital
signals should run above the digital ground plane, and
analog signals should run above the analog ground
plane.
Both devices have two power-supply inputs: analog
VDD (AVDD) and digital VDD (DVDD). Each AVDD input
should be decoupled with parallel 10F and 0.1F
ceramic chip capacitors. These capacitors should be
as close to the pin as possible, and their opposite ends
should be as close as possible to the ground plane.
The DVDD pins should also have separate 10F and
0.1F capacitors adjacent to their respective pins. Try
to minimize the analog load capacitance for proper
operation. For best performance, bypass with low-ESR
0.1F capacitors to AVDD.
The power-supply voltages should also be decoupled
with large tantalum or electrolytic capacitors at the
point they enter the PC board. Ferrite beads with addi-
tional decoupling capacitors forming a pi-network can
also improve performance.
