TS5070 - TS5071
APPLICATION INFORMATION
Figure 2 shows a typical application of the TS5070
together with a transformer SLIC.
The design of the transformer is greatly simplified
due to the on-chip hybrid balancecancellation filter.
Only one single secondary winding is required (see
application note AN.091 - Designing a subscriber
line card module using the TS5070/COMBO IIG).
Figures 3 and 4 show an arrangement with SGS-
Thomson monolithic SLICS.
POWER SUPPLIES
While the pins of the TS5070 and TS5071/COMBO
IIG devices are well protected against electrical
misuse, it is recommended that the standard
CMOS practice of applying GND to the device be-
14/32
fore any otherconnectionsare made shouldalways
be followed.In applicationswhere the printedcircuit
card may be plugged into a hot socket with power
and clocks already present, an extra long ground
pin on the connector should be used and a Schottky
diode connected between V
mize noise sources all ground connections to each
device should meet at a common point as close as
possible to the GND pin in order to prevent the in-
teraction of ground return currents flowing through
a common bus impedance. Power supply decou-
pling capacitors of 0.1 F shouldbe connectedfrom
this common device ground point to V
as closeto thedevice pins as possible.V
should also be decoupled with low effective series
resis-tance capacitorsof at least10 F locatednear
the card edge connector.
