| KS8737 Product Brief Revision 1.0 10/100 LV PHY FX Operating at 3.3 Volts to meet low voltage and low power requirement, the KS8737 is a 10/100BaseTX/FX Physical Layer Transceiver which provides MII interface for transmit and receive data. It contains the 100BaseTX/ FX Physical Medium Attachment (PMA), Physical Medium Dependent (PMD), and Physical Coding Sublayer (PCS) functions. Moreover, the KS8737 has an onchip 10BaseT encoder/decoder and output filtering, which eliminates the need for external filters and allows a single set of line magnetics to be used to meet the requirements for both 100BaseTX and 10BaseT. The KS8737 can automatically configure itself for 100 or 10 Mbps and full or half duplex operation, using the on-chip Auto-Negotiation algorithm. It's an ideal physical layer transceiver choice for 100BaseTX 100BaseFX/10BaseT applications.

A standard MII port is supplied for easy MAC integration. Management can be controlled by either strapping control pins or using the MII management port. A single port example of the KS8737 usage is shown below.
