DS1876T+TR规格书详情
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 modulation 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.
