9 Power Supply Recommendations

To help ensure reliable operation at data rates and supply voltages, a 0.1-μF bypass capacitor is recommended at input and output supply pins (V_CC1 and V_CC2). 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 or SN6505. For such applications, detailed power supply design and transformer selection recommendations are available in the SN6501 Transformer Driver for Isolated Power Supplies data sheet or the SN6505 Low-Noise 1-A Transformer Drivers for Isolated Power Supplies data sheet.
