GENERAL DESCRIPTION

The ML4665 is a low power, low cost, single chip 10BASE-FL transceiver. The ML4665 contains a fiber optic data quantizer and an LED output driver for direct connection to an optical module(s). The ML4665 offers a standard IEEE 802.3 AU interface that allows it to be directly connected to industry standard manchester encoder/decoder chips or an AUI connector.
