SATURN USER NETWORK INTERFACE
For optimal performance, the following guidelines should be followed:
• All power pins should be well decoupled, with the capacitors placed as close
as possible to the S/UNI power pins.
• Termination resistors and capacitors should be placed as close as possible to
the end of the transmission line.
• Source pull-down resistors should be placed as close as possible to the start
of the transmission line.
• Traces marked "Zo=50Ω" should be controlled impedance traces. These
traces should be kept as short as possible. Other controlled impedances can
be used. Contact PMC-Sierra's applications department for information on
using the S/UNI in "non-50Ω" controlled impedance environments.
• All inductors are Fair-Rite Products Corp #274-3019-446.
