Количество- Полное описание
The MAX3735AETG+T is a 2.7Gbps, low power SFP laser driver in 24 pin TQFN package. The device accept differential input data and provide bias and modulation currents for driving a laser. DC-coupling to the laser allows for multirate applications and reduces number of external components. It is fully compliant with the SFP MSA timing and the SFF-8472 transmit diagnostic requirements. An automatic power-control (APC) feedback loop is incorporated to maintain a constant average optical power over temperature and lifetime. It provide transmit-disable control, a single-point latched transmit-failure monitor output, photocurrent monitoring and bias-current monitoring to indicate when the APC loop is unable to maintain the average optical power. It is used in gigabit Ethernet SFP/SFF transceiver modules, multirate OC3 to OC48-FEC SFP/SFF transceiver modules and 1G/2G fibre channel SFP/SFF transceiver modules.
