Micro Linear ML6674
The ML6674 is a complete monolithic transceiver for 155Mbps NRZ encoded data transmission over category 5 unshielded twisted pair (UTP) and shielded twisted pair (STP) cables. The ML6674 is compliant with the ATM 155Mbps Twisted Pair Specification. The ML6674 includes the baseline restoration function and adaptive equalization which will accurately compensate for line losses exceeding 100m of UTP.| Part No. | ML6674 |

GENERAL DESCRIPTION
The ML6674 receive section consists of an equalizing filter with a feedback loop for controlling effective line compensation. The feedback loop contains a filter and detection block for determining the proper control signal. An ECL 100K compatible buffer at the output interfaces directly with ATM physical interface chips. The ML6674 transmit section accepts ECL 100K compatible NRZ inputs.FEATURES
