• Differential ECL compatible interface
• 5.0 V single power supply
• Pulse distortion control 0 ~ 350 psec
♦ Applications
• LED driver of an optical transmitter circuit up to
266 Mb/s
♦ 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.

♦ Precautions
Owing to their small dimensions, the GaAs FET’s from which the F0601720Q is designed
are easily damaged or destroyed if subjected to large transient voltages. Such transients
can be generated by power supplies when switched on if not properly decoupled. It is also
possible to induce spikes from static-electricity-charged operations or ungrounded equip-
ment.
