- Full Refund if you don't receive your order
General Description
Operating with a 2.5V core to meet low-voltage and low power 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.
Features
• Single chip 100BASE-TX/100BASE-FX/10BASE-T physical layer solution
