General Description
The GD16521 is a high performance low
power 2.5 Gbit/s Laser Driver with
optional on chip re-timing of data.
The GD16521 is designed to meet and
exceed ITU-T STM-16 and SONET
OC-48 fiberoptic communication systems
requirements.
The GD16521 is designed to sink a Mod-
ulation Current into the IM pin and a
Pre-Bias Current into the IB pin. The
Modulation Current is adjustable up to
50 mA and the Pre-Bias Current is ad-
justable up to 100 mA. The device fea-
tures two control loops for stabilizing the
laser diode operating conditions. An au-
tomatic optical power control loop main-
tains a constant average optical power
out of the laser diode, independent of
changes in the threshold current of the
laser diode. A modulation current control
loop maintains a constant modulation
current for the laser diode, or alterna-
tively maintains a constant extinction ra-
tio of the laser diode.
Re-timing of the data signal connected to
the pins SDIP/SDIN is made by means of
a DFF-clocked by an external clock sig-
nal at the data rate fed to the pins SCIP/
SCIN.
The GD16521 requires a single +3.3 V
supply.
The circuit is available as:
48 lead 7 × 7 mm TQFP power
enhanced plastic package
die.
