88E1240
OVERVIEW
FEATURES
The Alaska® Quad family of single-chip devices
- contains four independent Gigabit Ethernet trans-
- ceivers on a single monolithic IC. Each transceiver
- performs all the physical layer functions for
100BASE-TX and 1000BASE-T full or half-duplex Ethernet on CAT 5 twisted pair cable, and 10BASE-
- T full or half-duplex Ethernet on CAT 3, 4, and 5
- cable.
The Alaska 88E1240 device supports the Serial
- Gigabit Media Independent Interface (SGMII) for
- direct connection to a MAC/Switch port.
- The 88E1240 device is fully pliant with the IEEE 802.3 standard. The 88E1240 device includes
- the PMD, PMA, and PCS sublayers. The 88E1240 device performs PAM5, 8B/10B, 4B/5B, MLT-3,
- NRZI, and Manchester encoding/decoding; digital clock/data recovery; stream cipher scram-
- bling/descrambling; digital adaptive equalization for the receiver data path as well as digital filtering for
- pulse-shaping for the line transmitter; and Auto-
- Negotiation...
