SFP Controller with Dual LDD Interface
DS1876
19-5153; Rev 0; 2/10
General Description
The DS1876 controls and monitors all functions for
dual transmitter modules. The memory map is based
on SFF-8472. The DS1876 supports APC and modula-
tion control and eye safety functionality for two laser
drivers. It continually monitors for high output current,
high bias current, and low and high transmit power to
ensure that laser shutdown for eye safety requirements
are met without adding external components. Six ADC
channels monitor VCC, temperature, and four external
monitor inputs that can be used to meet all monitoring
requirements.
