The exposed pad is the primary thermal path and also the ground return for the high-speed RF path — it needs a solid via array under the pad to the ground plane. Rework is manageable with hot air if the board has a solder dam around the pad; the part is small enough that the pad wicks heat quickly. ## Lifecycle and sourcing posture ROHS3 compliant. There is no official second-source or pin-compatible alternate from another manufacturer at this data rate — the part is proprietary to Maxim (now Analog Devices). For BOM resilience, the active status means it can be specified into new designs without immediate LTB risk.","metaTitle":"MAX3946ETG+ Laser Diode Driver, 11.3 Gbps, 24-TQFN","metaDescription":"Maxim MAX3946ETG+ single-channel laser diode driver. 11.3 Gbps data rate, 80 mA bias/modulation, 2.85-3.63V supply, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Type":"Laser Diode Driver","Package":"Tray","Data Rate":"11.3Gbps","Mounting Type":"Surface Mount","Current - Bias":"80 mA","Package / Case":"24-WFQFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Supply":"68 mA","Voltage - Supply":"2.85V ~ 3.63V","Number of Channels":"1","Current - Modulation":"80mA","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"24-TQFN (4x4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.54","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$9.54000","currency":"USD"},{"qty":10,"price":"$8.62100","currency":"USD"},{"qty":25,"price":"$8.22000","currency":"USD"},{"qty":100,"price":"$7.13730","currency":"USD"},{"qty":250,"price":"$6.81648","currency":"USD"},{"qty":500,"price":"$6.21504","currency":"USD"},{"qty":1000,"price":"$5.41310","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/MAX3946.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the data rate of MAX3946ETG+?","answer":"The MAX3946ETG+ is rated for 11.3 Gbps data rate, covering 10 GbE, 10G Fibre Channel, and OTU2/OTU2e line rates."},{"question":"What is the modulation current of MAX3946ETG+?","answer":"The modulation current is 80 mA, matched to the bias current of 80 mA.
