Product details

3.5 Gbps laser diode driver in 32-LQFP

The Intel FAGD16573A32BA is a single-channel laser diode driver in a 32-LQFP package (5x5 mm body, 0.8 mm pitch). It handles data rates up to 3.5 Gbps, making it a fit for SFP+ optical modules and short-reach fiber-optic transceivers where the modulation current and bias current need independent control.

Supply rails and modulation current

The bias current is set at 50 mA, and the modulation current is 70 mA — these two parameters define the optical output power and extinction ratio in the laser diode. The total supply current draw is 75 mA.
