PX5410

www.DataSheet4U.com PX5410 Multi-Rate VCSEL Driver Product Brief January 2004 Description 4 PX5 10 Features Up to 4.25 Gb/s serial VCSEL driver Single +3.3 V supply Average power control (APC) provides constant output optical power Digital diagnostics provided with bias, photodiode, and temperature monitors Independent temperature compensation for VCSEL bias and modulation current VCSEL fault protection limits output optical power for laser safety Differential CML compatible inputs with on-chip termination 4 mm x 4 mm QFN package The growing use of the Internet and the increasing demand for storage area network (SAN) solutions has created the need for next generation physical layer ICs. In addition the introduction of 4 G Fiber Channel (4GFC) has introduced the need for next generation ICs to be backwards compatible with 1 G and 2 G Fiber Channel. The Zarlink PX5410 provides a multi-rate VCSEL driver solution for 1, 2, and 4GFC. The Zarlink PX5410 Multi-Rate VCSEL Driver is designed for various applications up to 4.25 Gb/s. It consists of a DC-coupled amplifier with adjustable modulation and bias currents optimized for driving commercially available VCSEL-based transmit optical sub assemblies (TOSAs) from a single +3.3 V supply. VCSEL modulation and bias currents can be programmed by a variety of means including external resistors, programmable potentiometers, SFF-8472 controllers, or microcontroller DAC outputs. Selectable temperature compensation and c...
