THE WORLD#39;S FIRST 3.3 Multirate VCSEL DRIVER common-collector, meets all the requirements SFP Module with Digital Diagnostics
Maxim Integrated Products is 3.3 multispeed MAX3740 VCSEL driver with a common manifold and automatic power adjustment. Along with the device DS1858 (new nonvolatile temperature sensor) the world#39;s first multispeed MAX3740 VCSEL driver meets all the requirements of SFP modules with Digital Diagnostics SFF-8472. This device is ideal for short-optical modules SFP/SFF-8472.
MAX3740 VCSEL driver has the best performance in the world. Manufactured by second-generation SiGe technology company Maxim, MAX3740 has a small size, excellent wave characteristics and competitive price. MAX3740 has a rise time of 65 ps, 12 ps and 1.3 ps deterministic random transients.
This device has a programmable peak current that can facilitate communication with all of VCSEL devices. MAX3740 has a capacity of 1 Gbit / s to 3.2 Gb / s and can be used in equipment for networks of Gigabit Ethernet, fiber optic, and OC-48.
MAX3740 outputs a control displacement and power, blocking the transmitter and the transmitter output protection from damage. MAX3740 provides the ability to produce digital diagnostic output without any additional components.
Operating from a single 3.3V supply, MAX3740 has a programmable bias current range from 1 mA to 15 mA, and a programmable modulation current range from 2 mA to 15 mA. VCSEL driver may have a differential output or a common collector.
MAX3740 manufactured in a 4 mm x 4 mm 24-lead QFN package and has an extended operating temperature range from -40 ° C to 85 ° C. For demonstration unit available kits.
