It takes a small-signal input from a photodiode transimpedance amplifier and outputs a clean, amplitude-limited differential signal for clock and data recovery. The four channels let a single device handle multiple fiber lanes or redundant paths on one board. The 48-TQFP exposed pad package (7x7 mm) pulls heat out through the PCB ground plane, which matters when the part runs continuously at line rate. ## Active lifecycle — still a current production part Note the RoHS non-compliant marking — this part uses lead-bearing solder terminations, so verify your assembly line's exemption status before committing the BOM. ## Package and thermal — the exposed pad is not optional The 48-TQFP exposed pad (EP) is the primary thermal path. Solder the pad to a copper land on the PCB with thermal vias to the ground plane — without that connection, junction temperature rises quickly under continuous 2.5 Gbps operation. The 0.5 mm pitch TQFP is a standard footprint for optical modules; layout guides from Maxim's application notes for this family recommend a 4-layer stack with the EP stitched to the inner ground layer.","metaTitle":"MAX3822UCM 2.5Gbps Quad Limiting Amplifier, 48-TQFP EP","metaDescription":"MAX3822UCM quad limiting amplifier for 2.5Gbps optical networks.

It accepts small differential input signals from a transimpedance amplifier and provides a limited output swing suitable for driving CDR or deserializer inputs at 2.5 Gbps per channel."},{"question":"Is the MAX3822UCM RoHS compliant?","answer":"No, the MAX3822UCM is marked as RoHS non-compliant. It contains lead in the solder terminations. For RoHS-exempt applications (military, aerospace, some industrial) this is acceptable; for standard commercial lead-free assembly, verify your exemption or look for a lead-free variant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX3822UCM","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX3822UCM when reusing this data.
