Functional Description
The F0601720Q is a high performance GaAs LED driver IC applying in an optical trans-
mitter module up to 266 Mb/s NRZ data rate. The F0601720Q specifies the rise time and the
fall time of 600 psec (10%-90%) typically. It features the single 5.0 V supply operation.
Package is 20-terminal Quad Flat Package (QFP).

User's Guide
(1) Application of Dly1 and Dly2
The two terminals permit presettable compensation of pulse width distortion at input sig-
nals In1 and In2 by connecting to GND as shown in Table1.
Table 1.
(2) Application of Tr1
The Tr1 terminal permits presettable voltage at Vbb by adjusting the valuable resistor (0
to 1k
) connected with GND as shown in Table2.
Table 2.
