KSZ8721BL 3.3V Integrated Circuit Chip 10 / 100BASE - TX/FX MII Physical Layer Transceiver
General Description
Operating with a 2.5V core to meet low-voltage and lowpower requirements, the KS8721BL and KS8721SL are 10BASE-T/100BASE-TX/FX Physical Layer Transceivers that use MII and RMII interfaces to transmit and receive data. They contain 10BASE-T Physical Medium Attachment (PMA), Physical Medium Dependent (PMD), and Physical Coding Sub-layer (PCS) functions. The KS8721BL/SL also have on-chip 10BASE-T output filtering. This eliminates the need for external filters and allows a single set of line magnetics to be used to meet requirements for both 100BASE-TX and 10BASE-T. The KS8721BL/SL automatically configure themselves for 100 or 10Mbps and full- or half-duplex operation, using an on-chip auto-negotiation algorithm. They are the ideal physical layer transceiver for 100BASE-TX/ 10BASE-T applications.
Features
• Single chip 100BASE-TX/100BASE-FX/10BASE-T physical layer solution
• 2.5V CMOS design; 2.5/3.3V tolerance on I/O
• 3.3V single power supply with built-in voltage regulator;
Power consumption <340mW (including output driver current)
• Fully compliant to IEEE 802.3u standard
• Supports MII and Reduced MII (RMII)
• Supports 10BASE-T, 100BASE-TX, and 100BASE-FX with Far_End_Fault Detection
• Supports power-down and power-saving modes
• Configurable through MII serial management ports or via external control pins
Functional Diagram
Features (continued)
• Supports auto-negotiation and manual selection for 10/100Mbps speed and full-/half-duplex modes
• On-chip, built-in, analog front-end filtering for both 100BASE-TX and 10BASE-T
• LED outputs for link, activity, full-/half-duplex, collision, and speed
• Supports back-to-back, FX to TX for media converter applications
• Supports MDI/MDI-X auto-crossover
• KS8721BL is a drop-in replacement for the KS8721BT in the same footprint
• KS8721SL is a drop-in replacement for the KS8721B in the same footprint
• Commercial Temperature Range: 0o C to +70o C
