⢠IEEE 1149.1 (JTAG) boundary scan
⢠128-pin MQFP, 117-pin BGA, and 100-pin FBGA packages
⢠Simplifies system and board design.
- Reduced I/O pin requirements with RGMII (over 50%).
- Clock timing can be adjusted to eliminate board trace delays
required by the RGMII specification.
⢠Provides interoperability with IEEE standard devices operating at 10,
100, and 1000 Mbps at half- and full-duplex.
⢠Lowers system BOM cost and simplifies system design.
⢠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.
