SFP optical module controller features dual-receiver interface

Sunnyvale, Calif.—Maxim Integrated Products has introduced the DS1877, an SFP video controller with a dual-receiver interface.

The DS1877 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. Paired with the DS1876 (an SFP controller with dual laser driver interface), the DS1877 enables full-featured optical video modules at a fraction of the cost of microcontroller-based designs, according to Maxim.

The DS1877 monitors four analog 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.

Pricing: $1.75 starts at $1.75 (1000-up, FOB USA).
