10 Power Supply Recommendations

To help ensure reliable operation at data rates and supply voltages, a 0.1-

μF bypass capacitor is recommended

at the input and output supply pins (VCC1 and VCC2). The capacitors should be placed as close to the supply pins

as possible. If only a single primary-side power supply is available in an application, isolated power can be

generated for the secondary-side with the help of a transformer driver such as Texas Instruments' SN6501. For

such applications, detailed power supply design and transformer selection recommendations are available in

SN6501 data sheet (SLLSEA0).
