622 Mbps to 3.2 Gbps limiting amplifier for Ethernet links
The Maxim MAX3746HETE is a limiting amplifier designed for Ethernet applications, covering data rates from 622 Mbps to 3.2 Gbps. This part recovers and reshapes incoming signals in optical or electrical serial links, providing a clean, amplitude-limited output for downstream clock-and-data recovery.
Active lifecycle, but RoHS non-compliant — plan the BOM accordingly
Plan for an exemption or a separate leaded-process line. The 16-TQFN-EP package is MSL-rated per the datasheet; store the reels in a dry cabinet or bake before reflow if the moisture-barrier bag has been opened past the floor-life window.
Package and thermal: 16-TQFN-EP (3x3 mm) with exposed pad
The MAX3746HETE is supplied in a 16-WFQFN with an exposed pad, also described as a 16-TQFN-EP measuring 3x3 mm. The surface-mount package suits automated assembly and reflow processes, but the leaded finish (RoHS non-compliant) means the reflow profile should match tin-lead solder, not SAC305.
