APPLICATION INFORMATION

power supplies

While the pins of the TP1306xB and TP306xB families are well protected against electrical misuse, it is

recommended that the standard 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 can 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 ANLG GND. This

minimizes the interaction of ground return currents flowing through a common bus impedance. VCC and VBB

supplies should be decoupled by connecting 0.1-

µF decoupling capacitors to this common point. These bypass

capacitors must be connected as close as possible to VCC and VBB.

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-µF capacitors.
