Functional Block Diagram
Functional Description
As shown on the block diagram above, the driver is
composed from an input buffer, Enable and polarity
block, and output buffer. In order to accommodate
VCSELs with different polarity and keep the data non
inverted, the input data polarity can be inverted by
setting pin 6 (POL) high. The modulation current into the
VCSEL is determined by the ratio between the output

voltage swing and the total load including VCSEL’s
equivalent resistance and any damping series resistor.
The output signal amplitude is determined by the voltage
applied at pin 10 (VCTRL) which should be within the
range of VCC-1.42 to VCC.
