Application Note

the TX pair is determined by the type of magnetic
you choose for your design. We suggest a magnetic
with a 1:1 ratio on the RX pair and a ratio of 1:
√
2 on
the TX pair. The recommended transformer is the
Pulse H1119. This provides effective coupling to the
Network by matching the impedance of the traces to
the impedance of the cable.
The RX termination resistors should be located as
close to the pins as possible.

CardBus Applications
When implementing the MT933 into applications
where the board area is limited, such as CardBus
Applications, alternative methods for splitting the
TXVDD
and
RXVDD
power
planes
may
be
recommended. If the VDD islands created have an
area of much less than 1 square inch, the planar
properties are lost and the planes should be joined
together to form a single Analog VDD (AVDD) plane.

Power Supply Decoupling
Decoupling of power supplies is very important to
help ensure the success of the design. Values for the
decoupling components are shown in the schematic
diagram. The values, locations, and number of
components
shown
represent
conditions for the MT933. Based on your application
alternative decoupling schemes may be necessary,
including less decoupling or different component
values.
