GENERAL DESCRIPTION The fully pin-compatible ML4664/ML4669 pair provide conversion from 10BASE-T copper media to 10BASE-FL fiber media in a single chip. They are compliant with Ethernet IEEE 802.3 10BASE-T and 10BASE-FL standards. The ML4664/69 uses a single 5V supply, and requires no crystal or clock. FEATURES ■ Full duplex operation ■ Five network status LED outputs ■ Industrial temperature option 10BASE-FL FEATURES: ■ Highly stable data quantizer with 55dB input dynamic range ■ Input sensitivity as low as 2mVP-P ■ Up to 100mA maximum current driven fiber optic LED output for accurate launch power (PLCC package) 10BASE-T FEATURES: ■ Current driven output for low RFI noise and low jitter ■ Drives 100W unshielded or 150W shielded twisted pair ■ Polarity detect status pin capable of driving an LED ■ Automatic polarity correction ■ On-chip link test with enable/disable option
