Supply Bypassing and PCB Layout Guidelines
TheLTC6994isanaccuratemonostablemultivibratorwhen
used in the appropriate manner. The part is simple to use
and by following a few rules, the expected performance is
easily achieved. Adequate supply bypassing and proper
PCB layout are important to ensure this.
Figure 16 shows example PCB layouts for both the SOT-23
and DCB packages using 0603 sized passive components.
The layouts assume a two layer board with a ground plane
layer beneath and around the LTC6994. These layouts are
a guide and need not be followed exactly.
1. Connect the bypass capacitor, C1, directly to the V+ and
GND pins using a low inductance path. The connection
from C1 to the V+ pin is easily done directly on the top
layer. For the DCB package, C1’s connection to GND is
also simply done on the top layer. For the SOT-23, OUT
can be routed through the C1 pads to allow a good C1
GND connection. If the PCB design rules do not allow
that,C1’sGNDconnectioncanbeaccomplishedthrough
multiple vias to the ground plane. Multiple vias for both
the GND pin connection to the ground plane and the
C1 connection to the ground plane are recommended
to minimize the inductance. Capacitor C1 should be a
0.1F ceramic capacitor.
2. Place all passive components on the top side of the
board. This minimizes trace inductance.
3. Place RSET as close as possible to the SET pin and make
adirect,shortconnection.TheSETpinisacurrentsum-
ming node and currents injected into this pin directly
modulate the output delay. Having a short connection
minimizes the exposure to signal pickup.
4. Connect RSET directly to the GND pin. Using a long path
or vias to the ground plane will not have a significant
affect on accuracy, but a direct, short connection is
recommended and easy to apply.
5. Use a ground trace to shield the SET pin. This provides
another layer of protection from radiated signals.
6. Place R1 and R2 close to the DIV pin. A direct, short
connection to the DIV pin minimizes the external signal
coupling.
