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 LANCheck® online design review service is available for customers who have selected our products for their application design-in. The LANCheck online design review service is subject to Microchip's Program Terms and Conditions and requires a myMicrochip account.
