Pin Function
Supply Voltage. Bypass with a 0.1μF//0.01μF low ESR capacitor as close to VCC pin as
possible.
Ground. Ground and exposed pad must be connected to the plane of the most negative
potential.
Non-inverting input data. Internally terminated with 50 ? to a reference voltage.
Inverting input data. Internally terminated with 50 ? to a reference voltage.
Modulation current setting and control. The voltage applied to this pin will set the modulation
current. Input impedance 25k ? .
Active Low TTL. The driver is disabled when this pin is unconnected or /EN asserted high. The
driver is enabled when /EN is asserted low.
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.
BIAS Current Output
Bias monitor. Install an external resistor from this pin to GND to convert the output current to a
voltage proportional to the bias current
Bias current setting. The voltage applied to this pin will set the bias current. Input impedance
25k ? .
