9.2.3 Application Curves

The typical eye diagram of the ISO776x family of devices indicates low jitter and a wide open eye at the

maximum data rate of 100 Mbps.

10 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 (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 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.
