Laser Controller
U8600B
Description
The U8600B is a monolithic integrated circuit using
TEMIC’s advanced UHF technology. The IC is a very
high-speed, mixed–signal laser driver circuit for
re-writable optical systems.
It comprises a servo amplifier to drive the laser diode, a
high-frequency modulator for noise reduction, power and
pulse-width generators as well as several operation con-
trol and safety functions.
Features
D Single + 5 V power supply
D Data transfer rates up to 16 Mb/s
D Servo system
– High bandwidth: 100 MHz
– High dc gain: 110 dB
– High LD drive current: typ. 100 mA, max. 180 mA
– High slew rate: 5 ns rise/ fall time
– Servo gain adjustable
D Noise reduction by servo loop and weak high-
frequency modulation
D On-chip generation of power levels for read, erase,
and write operations
D On-chip generation of write and off-pulse widths:
15 to 90 ns, 5 ns steps
D Digital control of power and pulse parameters via a
serial 3-wire interface
D Basic power level adjustable
D Supervision of power supply, laser current and laser
power
D Laser shutdown to prevent laser damage and data loss
Package:
44-lead shrinked small-outline IC (SSO44)
Thermal resistance: RthJC = 22°C/W

(*) Test circuit with electrical feedback on page 10. Measurement with sampling head with 300 ps sampling time.
Peak-to-peak value of 1200 measurements, each measurement represents the average of 64 samples. These
noise values ensure a stable operation of the servo amplifier for Tamb = 0 to 75°C.
