Micro Linear ML6695

The ML6695 implements the physical layer of the Fast Ethernet 100BASE-X standard for fiber media. The device provides the 5-bit (or symbol) interface for interface to upper-layer silicon. The ML6695 integrates the data quantizer and the LED driver, allowing the use of low cost optical PMD components.

GENERAL DESCRIPTION

The ML6695 includes 125MHz clock recovery/clock generation, an LED driver, and a data quantizer (post amplifier). The device also offers a power down mode which results in total power consumption of less than 20mA. The ML6695 is suitable for the current 100BASE-FX IEEE 803.2u standard defined using 1300nm optics, as well as for the proposed 100BASE-SX standard defined using lower cost 820nm optics.
