Applications Information
POWER SUPPLIES
While the pins of the TP3060 family are well protected
against electrical misuse it is recommended that the stan-
dard CMOS practice be followed ensuring that ground is
connected to the device before any other connections are
made In applications where the printed circuit board may be
plugged into a ‘‘hot’’ socket with power and clocks already
present an extra long ground pin in the connector should
be used
All ground connections to each device should meet at a
common point as close as possible to the GNDA pin This
Typical Asynchronous Application

minimizes the interaction of ground return currents flowing
through a common bus impedance 0 1
pling capacitors should be connected from this common
ground point to V
possible
For best performance the ground point of each CODEC
FILTER on a card should be connected to a common card
ground in ‘‘STAR’’ formation rather than via a ground bus
This common ground point should be decoupled to V
V
