9.3 Power Supply Recommendations

To help provide reliable operation at data rates and supply voltages, a 0.1-μF bypass capacitor must be placed at input and output supply pins (VCC1 and VCC2). The capacitors must 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 device. For such applications, detailed power supply design and transformer selection recommendations are available in the SN6501 Transformer Driver for Isolated Power Supplies data sheet.
