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
