DS1877 SFP video controller

Maxim Integrated Products rolls the DS1877 video controller with a dual-receiver interface that enables full-featured optical video modules at a fraction of the cost of microcontroller-based designs.

The video controller controls and monitors all receiver functions for SFP and SFP+ optical modules and fully supports the SFF-8472 specification. The DS1877 controls dual-receiver SFP modules and enables the low-cost implementation of SDI digital video and other optical video applications. Its state-machine approach eliminates the need for expensive microcontrollers and, in turn, avoids the costly software development they require.

The DS1877 monitors four analogue channels: temperature, Vcc, and two external differential signals. Loss of signal (LOS) is continuously monitored in both receiver channels, and all LOS functionality is supported.

The DS1877 is fully specified over the -40°C to +95°C temperature range, and is available in a 5mm x 5mm, 28-pin TQFN package. Pricing starts at Rs.81.72 ($1.75) (1,000-up, FOB USA).
