SFP Controller for Dual Rx Interface
DS1877
19-5188; Rev 1; 4/10
General Description
The DS1877 controls and monitors all functions for SFF,
SFP, and SFP+ modules including all SFF-8472 func-
tionality. The device supports all LOS functions for two
receivers, and continually monitors for LOS of either
channel. Four ADC channels monitor VCC, temperature,
and two differential external monitor inputs that can be
used to meet all monitoring requirements. Two digital-
to-analog converter (DAC) outputs with temperature-
indexed lookup tables (LUTs) are available for additional
monitoring and control functionality.
Applications
SFF, SFP, and SFP+ Transceiver Modules
Dual Rx Video SFPs
