    Products Detail

    The KSZ8091 is a single-supply 10Base-T/100Base-TX Ethernet physical-layer transceiver for transmission and reception of data over standard CAT-5 unshielded twisted pair (UTP) cable. The KSZ8091 is a highly-integrated PHY solution. It reduces board cost and simplifies board layout by using on-chip termination resistors for the differential pairs, integrating a low-noise regulator to supply the 1.2V core and by offering a flexible 1.8/2.5/3.3V digital I/O interface.

    The KSZ8091MNX and KSZ8091MLX offer the Media Independent Interface (MII), while the the KSZ8091RNx offer the Reduced Media Independent Interface (RMII) for direct connection with MII/RMII-compliant Ethernet MAC processors and switches.

    Wake-on-LAN (WOL) provides a mechanism for the KSZ8091 to wake up a system that is in standby power mode. The KSZ8091 provides diagnostic features to facilitate system bring-up and debugging in production testing and in product deployment. Parametric NAND tree support enables fault detection between KSZ8091 I/Os and the board. Microchip's LinkMD® TDR-based cable diagnostics identify faulty copper cabling. 

    The KSZ8091RNA and KSZ8091RND are available in a 24-pin (4mm x 4mm) QFN package. The KSZ8091MNX and KSZ8091RNB are available in a 32-pin, lead-free QFN packages. The KSZ8091MLX is available in a 48-pin (7mm x 7mm) LQFP package.


    Microchip's complimentary and confidential MicroCHECK design review service, which offers insight from the initial concept to the final PCB layout, is available to customers who are using our products in their projects. You can confidently submit your design materials in a secure and private setting, and our expert engineers will provide individualized feedback to enhance your design. MicroCHECK design review service is subject to Microchip's Program Terms and Conditions and requires a myMicrochip account.
