Pin Function
Ground. Ground and exposed pad must be connected to the plane of the most negative
potential.
Non-inverting input data. Internally terminated with 50Ω to a reference voltage.
Inverting input data. Internally terminated with 50Ω to a reference voltage.
Supply Voltage. Bypass with a 0.1µF//0.01µF low-ESR capacitor as close to VCC pin as
possible.
Inverted modulation current output. Outputs modulation current when input data is negative.
Non-inverted modulation current output. Outputs modulation current when input data is
positive.
Reference Voltage. Install a 0.1µF capacitor between VREF and VCC.
Modulation current setting and control. The voltage applied to this pin will set the
modulation current. To be connected to the MIC3003 pin 24 (VMOD+). Input impedance
25KΩ.
A low-level signal on this pin will enable the output stage of the driver. Internally pulled
down with 75KΩ.
