DS1873: SFP+ optical module controller with analog LDD interface provides full compatibility with the SFF-8472 specification

Laser modulation is controlled by a temperature driven LUT. Two additional 9-bit DAC outputs with 36-entry LUTs are provided. The DS1873 monitors six analog channels: temperature, Vcc, and MON1-MON4. MON3 is a fully differential input. In its small 5mm x 5mm package, the DS1873 completely and efficiently fulfills a critical requirement for SFP+ optical module manufacturers.

The DS1873 is fully specified over the -40 degrees Celsius to +95 degrees Celsius temperature range, and is available in a 28-pin TQFN package with exposed pad. Pricing begins at $1.39 (1000-up, FOB USA).
