Intel^®LXT901A/907A Universal 3.3 V

Ethernet Transceiver

Datasheet

The Intel^®LXT901A and LXT907A Transceivers (called hereafter the LXT901A/907A

Transceivers) are new generation Universal Ethernet Transceivers with improved noise

immunity and output filtering. The feature set of the LXT901A/907A has been streamlined,

removing Remote Signaling capabilities. The LXT901A and LXT907A provide all the active

circuitry to interface most standard IEEE 802.3 controllers to either the 10BASE-T media or

Attachment Unit Interface (AUI).

The LXT901A and LXT907A Transceivers are identical except for the function of one pin. The

LXT901A Transceiver, with selectable termination impedance, allows the use of either shielded

or unshielded twisted-pair cable. The LXT907A Transceiver offers a Signal Quality Error

Disable (DSQE) function.

The LXT901A/907A Transceivers functions include Manchester encoding/decoding, receiver

squelch and transmit pulse shaping, jabber, link testing, and reversed polarity detection/

correction.
