APPLICATION INFORMATION
Figure 2 showsa typicalapplicationof the TS5070
togetherwith a transformerSLIC.
The design of the transformer is greatly simplified
dueto theon-chiphybridbalancecancellationfilter.
Onlyonesinglesecondarywindingis required(see
application note AN.091 - Designing a subscriber
line card module using the TS5070/COMBOIIG).
Figures 3 and 4 show an arrangement with SGS-
ThomsonmonolithicSLICS.
POWERSUPPLIES
Whilethepinsof theTS5070and TS5071/COMBO
IIG devices are well protected against electrical
misuse, it is recommended that the standard
CMOS practice of applyingGND to the device be-

befollowed.Inapplicationswheretheprintedcircuit
