Part Name(s) : MAX3946_10 MAX3946ETG+_10 MAX3946ETG_10 MaximIC
Maxim Integrated
Description : 1.0625Gbps TO 11.3Gbps, SFP+ LASER DRIVER WITH LASER IMPEDANCE MISMATCH TOlerance View

General Description
The MAX3946 is a +3.3V, multirate, low-power LASER diode DRIVER designed for Ethernet and Fibre Channel transmission systems at data rates up TO 11.3Gbps. This device is optimized TO drive a differential transmitter optical subassembly (TOSA) WITH a 25I flex circuit. The unique design of the output stage enables use of unmatched TOSAs, greatly reducing headroom limitations and lowering power consumption.
The device receives differential CML-compatible signals WITH on-chip line termination. It can deliver LASER modulation current of up TO 80mA, at an edge speed of 22ps (20% TO 80%), inTO a 5I TO 25I external differential load. The device is designed TO have a symmetrical output stage WITH on-chip back terminations integrated inTO its outputs. A high-bandwidth, fully differential signal path is implemented TO minimize deterministic jitter. An equalization block can be activated TO compensate for the SFP+ connecTOr. The integrated bias circuit provides programmable LASER bias current up TO 80mA. Both the LASER bias generaTOr and the LASER modulaTOr can be disabled from a single pin.
A 3-wire digital interface reduces the pin count and permits adjustment of input equalization, pulse-width adjustment, Tx polarity, Tx deemphasis, modulation current, and bias current WITHout the need for external components. The MAX3946 is available in a 4mm x 4mm, 24-pin TQFN package.
