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 monitoring 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 writeprotects calibration data. Programming is accomplished through an I²C-compatible interface, which can also be used to read diagnostic information.

Key Features		Applications/Uses
Automatic Power Control (APC) Automatic Extinction Ratio Control (AERC) Across Temperature and Laser Aging Works in AC-Coupled Laser Systems Configurable Latched Automatic Shutdown with Tx-Fault and Tx-Disable Programmable Fast Alarm Conditions I²C-Compatible Serial Interface Allows Up to Eight Devices on the Same Serial Bus Operates Over Wide Supply-Voltage Range Nonvolatile Memory for Device Settings Small, 14-Pin TSSOP Package -40°C to +95°C Operating Temperature Range		Optical Transceivers Optical Transponders
