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
