9.2.1.2 Detailed Design Procedure

The TS3DV642 is designed to operate with 2.6 V – 4.5 V power supply. The wide power supply range allows flexibility for battery powered applications. If a higher power supply is used in the system, a voltage regulator can be used to bring down the voltage to 2.6 V – 4.5 V range. Decoupling capacitors may be used to reduce noise and improve power supply integrity. AC coupling capacitors in 75 nF – 200 nF range must be placed on the MainLink (ML) and AUX lanes. In this particular application the AC coupling capacitors are shown on the connector side. The AC coupling capacitors may also be placed on the signal path on controller side. The AUX+ line must be pulled-down weakly through a resistor to ground and the AUX– line must be pulled-up weakly through a resistor to VCC.
