Additional Infomation About Product

KS8721B/BT Micrel, Inc. KS8721B/BT 2.5V 10/100BasTX/FX MII Physical Layer Transceiver Rev. 2.3 General Description Features Operating at 2.5 volts to meet low voltage and low power Single chip 100BaseTX/100BaseFX/10BaseT physical requirements, the KS8721B/BT is a 10BaseT/100BaseTX/ layer solution FX Physical Layer Transceiver, which provides an MII to 2.5V CMOS design, power consumption <200mW transmit and receive data. It contains the 10BaseT Physical (excluding output driver current ) Medium Attachment (PMA), Physical Medium Dependent Fully compliant to IEEE 802.3u standard (PMD), and Physical Coding Sub-layer (PCS) functions. Supports Media Independent Interface (MII) and Moreover, the KS8721B/BT has on-chip 10BaseT output Reduced MII (RMII) filtering, which eliminates the need for external filters and Supports 10BaseT, 100BaseTX and 100BaseFX with allows a single set of line magnetics to be used to meet Far End Fault Detection requirements for both 100BaseTX and 10BaseT. Supports power down mode and power saving mode Configurable through MII serial management ports or via The KS8721B/BT can automatically configure itself for 100 or external control pins 10 Mbps and full or half duplex operation, using on-chip Auto- Supports auto-negotiation and manual selection for Negotiation algorithm. It is an ideal choice of physical layer 10/100Mbps speed and full/half-duplex mode transceiver for 100BaseTX/10BaseT applications. On-chip built-in analog front end filtering for both Data sheets and support documentation can be found on 100BaseTX and 10BaseT Micrels web site at www.micrel.com.
