BCM5241A1IMLG Broadcom说明

Broadcom BCM5241 博通 10/100 以太网收发器
10/100BASE-TX SINGLE-CHANNEL TRANSCEIVER

FEATURES

• 10BASE-T/100BASE-TX/100BASE-EFX IEEE 802.3u fast
Ethernet transceiver
• HP auto-MDIX
• Advanced cable diagnostics (CableChecker™)
• Robust CESD tolerance
• Operation from a single 3.3V or 2.5V supply source
• Unique energy detect circuit
• Low-power mode
• Super isolate mode
• Cable length up to 160 meters
• MII and 7-wire serial interface
• Power dissipation: <170 mW

SUMMARY OF BENEFITS

• DSP-based architecture to ensure performance over
temperature, voltage and process variation.
- Field proven in over one billion Fast Ethernet ports.
- Superior ability to link and lower BER in marginal cable
plants, relative to analog solutions.
- Greater ATE coverage results in fewer field failures.
• Improved ease of use and installation, reduced support cost.
- Straight-through or cross-over cables accommodated
independent of installation.
- Advanced cable diagnostic features to enable remote
monitoring and debug of cabling infrastructure.
- Resistance to CESD to reduce product destruction and
product returns.
• Flexible power supply options.
• Low power and intelligent power management.
- Increased active working time.
- Prolonged battery life in active standby.
- Increased reliability.
• Control of network interaction on start up.

DSP-Based PHY Technology

The BCM5241 builds on Broadcom's proven DSP PHY design and full
custom circuit design techniques to create a highly-integrated and robust
physical layer solution. DSP techniques allow the BCM5241 to achieve
high interoperability and to exhibit robust performance across voltage
(+/-10%), temperature, and process variations. Broadcom's DSP-based,
Broad-Φ™ technology has been proven in the shipment of over one
billion Fast Ethernet ports. Due to the significantly greater test coverage
for a DSP based PHY, Broadcom's PHYs exhibit superior quality with a
failure rate of well under 10 PPM.
