SFP Optical Module Controller Enables Low-Cost Video

Promising to eliminate the costly software development required by microcontroller-based solutions, the DS1877 SFP video controller with a dual-receiver interface controls and monitors all receiver functions for SFP and SFP+ optical modules and fully supports the SFF-8472 specification. The device controls dual-receiver SFP modules and enables the low-cost implementation of SDI digital video and other optical video applications. It monitors four analog channels: temperature, Vcc, and two external differential signals. Loss of signal is continuously monitored in both receiver channels and all LOS functionality is supported. Available in a 28-pin TQFN measuring 5 mm x 5 mm, pricing starts at $1.75 each/1,000. MAXIM INTEGRATED PRODUCTS, Sunnyvale, CA. (800) 998-8800.
