DESCRIPTION
The M66516 is a semiconductor laser-diode driver/controller.
Its functions are the driving and laser power control of a spe-
cific type (Mitsubishi’s R type laser) of semiconductor laser
diode, in which the cathode of a semiconductor laser diode is
connected in stem structure to the anode of a monitoring
photodiode.
The IC has a laser drive current output pin of source type and
is capable of driving a laser diode on a maximum bias current
of 30mA and a maximum switching current of 120 mA, which
is switched at a rate of 20Mbits/sec.
Since the M66516 has a built in sample-hold circuit, it is pos-
sible to realize an internal APC
system that requires no ex-
ternal device for laser power control.
: Automatic Power Control
FEATURES
Built-in sample-hold circuit for APC function
High speed switching (20Mbps)
Large drive current (150mA max.)
Capable of setting bias current (30mA max.)
5V single power supply
APPLICATION
Semiconductor laser-diode applied equipment
