Note 1. Power on or off, measured from 75KHz to 1MHz at point A and transformer self impedance of 3KΩ minimum
at 1MHz.
Note 2: Power Supplies: +12 Volts ±0.75 V & +5 Volts ±0.25 V, bypassed by 10 µF (Tantalum recommended)
Capacitor minimum. All measurements & specifications apply over the temperature range of -55°C to +125°C
(case temperature) unless otherwise specified.
Note 3: When measured as shown per Figure 5 with ± 10 Volt peak, line to ground, DC to 2MHz
Note 4: Typical power is measured with VBUS at point A = 7.5 VP-P
