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
minimizes the interaction of ground return currents flowing
through a common bus impedance 01 mF supply decou-
pling capacitors should be connected from this common
ground point to VCC and VBB as close to the device as
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 VCC and
VBB with 10 mF capacitors
