Key Features
- Supports 18kB jumbo frames for 1000Base-T/100Base-TX and 10kB jumbo frames for 10Base-T.
- Supports Fiber-to-UTP or SGMII-to-RGMII, IEEE 802.3az EEE, WOL, interrupt output and link sleep mode.
- Parallel detection, crossover detection, auto correction and baseline-wander correction support robust Ethernet links.
Typical Applications
- Industrial Ethernet, embedded boards, switch/gateway equipment and domestic replacement of Ethernet interfaces.
- Design-in should confirm MAC mode, voltage domain, crystal/clocking plan, magnetics/RJ45 solution and driver support.
Design-in Notes
- Confirm host processor, FPGA or SoC interface support, voltage rails and package footprint constraints.
- Before sample design-in, share schematic, PCB stack-up, clock/reset design, power sequencing and replacement part information.
- For replacement projects, provide the original part number, operating temperature, speed grade, package constraints and lifecycle requirement.
Selection Support
For platform compatibility, replacement review, temperature range, package constraints or document status, please submit the target platform, expected volume and project phase. Kangda sales and FAE teams can follow up with that context.
