SFP+ controller with digital LDD interface supports all SFF-8472 functionality
Maxim Integrated Products introduces the DS1874, an SFP+ controller with a digital LDD interface. This device controls and monitors all functions for SFF, SFP, and SFP+ optical modules and fully supports the SFF-8472 standard. The combination of the DS1874 with a MAX3798 or MAX3799 laser driver/limiting amplifier provides a low-cost solution for APC loop control, modulation current control, and eye-safety functionality. This chipset eliminates the need for software development, thus reducing cost and speeding time to market.
The DS1874 monitors six analog channels: temperature, Vcc, and MON1-MON4, which can be used to meet all monitoring requirements. Laser modulation is controlled by a temperature-driven LUT to compensate for tracking error. Two DAC outputs with 36-entry LUTs are provided for additional monitoring and control functionality.The DS1874 utilizes 0.35micrometer technology to enable the implementation of all SFF-8472 functionality in its small, 5mm x 5mm, 28-pin TQFN package with exposed pad.
