Power-Supply Bypassing
Adequate power-supply bypassing is necessary to maxi-
mize performance and noise immunity. Bypass each
VCC pin to GND with high-frequency, low-ESR, X7R/X5R
10nF and 4.7FF surface-mount ceramic capacitors as
close as possible to the device.
Printed Circuit Board (PCB) Traces
Input and output trace characteristics affect the perfor-
mance of the device. Connect each of the inputs and
outputs to a 50I characteristic impedance trace in to
minimize reflections. Avoid discontinuities in differential
impedance and maximize common-mode noise immuni-
ty by maintaining the distance between differential traces
and avoiding sharp corners. Minimize the number of vias
to prevent impedance discontinuities. Reduce reflec-
tions by maintaining the 50I characteristic impedance
through connectors and across cables. Minimize skew
by matching the electrical length of the traces.
