Description
The Marvell Alaska family of Gigabit Ethernet (GbE) over copper transceivers, including the 88E1240-BAM1 model, are known for being the industry's lowest power, smallest form factor, highest performance, and highest port density solutions in volume production. These transceivers are optimized for the mobile computing market and support various Ethernet protocols such as 100BASE-TX, 1000BASE-T, and 10BASE-T. The 88E1240-BAM1 model also offers additional support for 1000BASE-X through an integrated 1.25 GHz Serializer/Deserializer (SERDES).
Specifications and features
- Low power dissipation, just over 1W
- IEEE 802.3 compliant 1000BASE-T, 100BASE-TX, and 10BASE-T transceivers
- Supports GMII, TBI, RTBI, RGMII, SGMII interfaces
- Integrated 1.25 GHz SERDES (88E1011S)
- Media Detect feature automatically detects and configures to either copper or fiber media
- Four power management modes
- Auto-MDI/MDIX crossover at all three speeds
- IEEE 1149.1 (JTAG) boundary scan support
- Advanced mixed-signal and DSP techniques
- Advanced baseline wander correction
- Fully integrated digital adaptive equalizers, echo and crosstalk cancellers
- On-chip transmit wave-shaping to reduce EMI
- Advice internal hybrids for 1000BASE-T
- Three package options: 128-pin PQFP, 117-pin TFBGA, and 96-pin BCC
- 0.15-micron standard digital CMOS process
Application Scenarios
The Marvell Alaska Ultra GbE transceiver, including the 88E1240-BAM1 model, supports advanced power management modes, including Wake-on-LAN, which are critical to client applications such as Gigabit-connected laptop computers. The device also provides complete flexibility in media selection - either copper or fiber media. The Alaska Ultra PHY's Media Detect feature automatically senses whether the end-user has inserted a CAT 5 copper or fiber-optic cable, performs Auto-Negotiation, and provides seamless plug-and-play configuration.
