Pin Description
Pin Name
Pin Number
Pin Function
1, 4, 7, 8, 13
GND
Ground. Ground and exposed pad must be connected to the plane of the most
negative potential.
2
DIN+
Non-inverting input data. Internally terminated with 50
to a reference voltage.
3
DIN–
Inverting input data. Internally terminated with 50
to a reference voltage.
5, 6
VCC
Supply Voltage. Bypass with a 0.1μF//0.01μF low ESR capacitor as close to VCC
pin as possible.
9, 10
MOD–
Inverted modulation current output. Outputs modulation current when input data is
negative.
11, 12
MOD+
Non-inverted modulation current output. Outputs modulation current when input
data is positive.
14
VREF
Reference Voltage. Install a 0.1μF capacitor between VREF and VCC.
15
IM_SET
Modulation current setting and control. The voltage applied to this pin will set the
modulation current. To be connected to the MIC3000/1 pin 24 (VMOD+). Input
impedance 25K
.
16
/EN
A low level signal on this pin will enable the output stage of the driver. Internally
pulled down with 75K
.
