ML4658

The ML4658 10BASE-T Transceiver is a single chip cable line driver/receiver that provides all of the functionality required to implement both an internal and external IEEE 802.3 10BASE-T MAU. This part offers a standard IEEE 802.3 AU interface that allows it to directly connect to industry standard manchester encoder/decoder chips or to an AUI cable.

The ML4658 requires a minimal number of external components, and is compliant to the IEEE 802.3 10BASE-T standard. The differential current driven transmitter offers superior performance because of its highly symetrical switching. This results in low RFI noise and low jitter.

The Transceiver ML4658 easily interfaces to 100W unshielded twisted pair cable, 150W shielded twisted pair cable, or a range of other characteristic impedances by simply changing one external resistor. Jabber, Link Test, and SQE Test are fully integrated onto the chip with enable/disable options. A polarity detection status pin, which can drive an LED, is provided for receive data, and the ML4658 offers automatic polarity correction.
