It delivers up to 100 mA bias current and 85 mA modulation current from a 2.97 V to 3.63 V supply rail, with the modulation current controlling the optical extinction ratio directly. The 24-TQFN (4x4 mm) package with exposed pad sits on a standard fibre-optic module PCB layout, and the -40°C to 85°C operating range covers central-office and outdoor telecom cabinet environments. ## Bias and modulation current — matching the laser diode The 100 mA bias current sets the DC operating point; the 85 mA modulation current is superimposed to produce the optical eye diagram. ## Active lifecycle and supply posture The MAX3646ETG+ carries an Active lifecycle status and ROHS3 compliance.","metaTitle":"MAX3646ETG+ Laser Diode Driver, 622Mbps, 24-TQFN","metaDescription":"Maxim MAX3646ETG+ laser diode driver for fiber optic, 622Mbps data rate, 100mA bias, 85mA modulation, 2.97-3.63V supply, -40 to 85°C.
