Maxim launches with digital laser diode driver (LDD) small form factor pluggable interfaces (SFP+) DS1878. DS1878 is based on a state machine, and eliminates the need for tedious work of software development. Devices to easily meet the requirements of SFF-8472 standard, shorten product time to market. In addition, as an ideal high reliability optical transceiver designers I2C controller options, DS1878 MEL SFP+ the reliability of optical transceiver modules.

DS1878 control and monitoring of SFF, SFP, and full functionality of the SFP+ module, fully meet the SFF-8472 criteria. Devices with a MAX3798 or MAX3799 laser driver/limiting amplifier SFP+ used, provide automatic power control (APC) loop, modulation current control, and Visual protection SFP+ and SFP optical modules core feature. DS1878 also work with MAX3945 or MAX3946 LDD a limiting amplifier, supported with distributed feedback lasers (DFB) or electro-absorption modulation (EML) 10GHz applications of lasers.

Laser modulation by a proprietary temperature-driven lookup table (LUT). In addition, providing two additional 9-bit σ-δ DAC outputs, temperature data of the LUT has 36. DS1878 monitors six analog channels: temperature, VCC, MON1 to MON4 MON3 is differential input. DS1878-+95 ° c-40 ° c temperature range, using the 0.35m process, naked pads with small size, 5mm x 5mm, 28-pin TQFN package required to meet SFF-8472 standards are highly integrated in all modules.
