Low-power limiting amplifier for fiber-optic receivers
The Maxim MAX3272EGP is a low-power limiting amplifier designed for fiber-optic receiver front-ends, where it restores the amplitude of a degraded optical signal to a logic-clean level for downstream clock-and-data recovery. Housed in a 20-VFQFN exposed-pad package (20-QFN, 4x4 mm), it mounts on the board with a surface-mount reflow profile and uses the exposed pad for thermal dissipation. The 'low-power' designation matters in dense line-card or small-form-factor optical modules where every milliwatt of receiver bias counts against the module power budget.
RoHS non-compliant status means this variant uses lead-bearing solder terminations — verify your assembly line's exemption or plan for the RoHS-compliant suffix if your process requires it.
Package and footprint — what the 20-QFN means for layout
Surface-mount assembly with a standard QFN footprint; the exposed pad is the main thermal path, so the solder paste coverage on the center pad should match the datasheet's recommended stencil aperture.
