Module
10/100/1000BASE-T SFP/GBIC Module
Simplifies system and board design
Reduced I/O pin requirements with RGMII (over 50%), SGMII (over
75%), and SerDes (over 80%)
Clock timing can be adjusted to eliminate board trace delays required
by the RGMII specification
Flexibility for copper or fiber applications
Lowers system BOM cost and simplifies system design
Provides interoperability with IEEE standard devices operating at 10,
100, and 1000 Mbps at half- and full-duplex
Requires no airflow or heatsink
Provides compliance with PCI 2.2 and PC99/PC2000
Eases system level debug
Reduces system design constraints to meet EMI emissions standards.
Cable diagnostic function characterizes cable plant condition and
immediately indicates cabling issues.
Prevents erroneous equipment return due to bad cable plants.
Prevents manufacturing fall-out due to bad cable plants.
High CESD tolerance prevents equipment damage and return.
Operates with larger packets for wider range of packet protocol
support and improved efficiency.
Ease of manufacturing with JTAG support, simplified power supply,
and multiple MAC interfaces.
