Limiting the Output Current
No output short circuit current limit exists on these parts. All
applications need to limit the output current to less than 40mA.
Adequate thermal heat sinking of the parts is also required.
PC Board Layout
The AC performance of this circuit depends greatly on the
care taken in designing the PC board. The following are
recommendations to achieve optimum high frequency
performance from your PC board.
The use of low inductance components, such as chip
resistors and chip capacitors, is strongly recommended.
Minimize signal trace lengths. Trace inductance and
capacitance can easily limit circuit performance. Avoid
sharp corners. Use rounded corners when possible. Vias
in the signal lines add inductance at high frequency and
should be avoided. PCB traces greater than 1" begin to
exhibit transmission line characteristics with signal rise/fall
times of 1ns or less. High frequency performance may be
degraded for traces greater than one inch, unless
controlled impedance (50
Ω or 75Ω) strip lines or
microstrips are used.
Match channel-to-channel analog I/O trace lengths and
layout symmetry. This will minimize propagation delay
mismatches.
Maximize use of AC decoupled PCB layers. All signal I/O
lines should be routed over continuous ground planes (i.e. no
split planes or PCB gaps under these lines). Avoid vias in the
signal I/O lines.
Use proper value and location of termination resistors. Input
termination resistors should be as close to the input terminal
as possible and output termination resistors as close to the
receiving device as possible.
When testing, use good quality connectors and cables,
matching cable types and keeping cable lengths to a
minimum.
A minimum of 2 power supply decoupling capacitors are
recommended (1000pF, 0.01F) as close to the devices as
possible. Avoid vias between the capacitor and the device
because vias add unwanted inductance. Larger capacitors
can be farther away. When vias are required in a layout, they
should be routed as far away from the device as possible.
The NIC pins are placed on both sides of the input pins.
These pins are not internally connected to the die. It is
recommended these pins be tied to ground to minimize
crosstalk.
The QFN Package Requires Additional PCB Layout
Rules for the Thermal Pad
The thermal pad is electrically connected to power supply
ground through the high resistance IC substrate. Its primary
function is to provide heat sinking for the IC. However,
because of the connection to the power ground pins through
the substrate, the thermal pad must be tied to the power
supply ground to prevent unwanted current flow through the
thermal pad. Maximum AC performance is achieved if the
thermal pad has good contact to the IC ground pins. Heat
sinking requirements can be satisfied using thermal vias
directly beneath the thermal pad to a heat dissipating layer
of a square at least 1” on a side.
