SFP+ controller combines with MAX3736 laser driver to control and monitor all functions for SFF, SFP, and SFP+ optical modules; fully supports the SFF-8472 standard.
SUNNYVALE, CA—March 15, 2010—Maxim Integrated Products (NASDAQ: MXIM) introduces the DS1873 SFP+ controller with analog LDD interface. Combined with the MAX3736 laser driver, the DS1873 controls and monitors all functions for SFF, SFP, and SFP+ optical modules, while fully supporting the SFF-8472 standard. Utilizing 0.35µm technology, the DS1873 implements a high level of integration key to APC loop, modulation current control, and eye safety functionality.
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°C to +95°C temperature range, and is available in a 28-pin TQFN package with exposed pad. Pricing begins at $1.39 (1000-up, FOB USA).
