Full Laser Control with Fault Management
General Description
The DS1861 is a laser-driver control IC designed to
reduce the production cost of fiber optics circuits by
eliminating multiple temperature tests. It works with
nearly all laser-driver ICs to provide automatic power
control (APC) and automatic extinction ratio control
(AERC), which improves the performance of the system
over temperature and aging. It also has built-in monitor-
ing capability to provide early fault detection, which can
be configured to latch the IC into a shutdown condition.
Settings programmed into the DS1861 are stored in
password-protected EEPROM memory, which write-
protects calibration data. Programming is accom-
plished through an I 2 C-compatible interface, which can
also be used to read diagnostic information.
