Single-chip gigabit Ethernet controllers reduce cost

Realtek Semiconductor has unveiled what it says is Asia's first single-chip gigabit Ethernet controllers–RTL8169S and RTL8110S–to cater for applications in broadband network designs.
The 32/64bit devices integrate a gigabit MAC (media access controller) and a gigabit physical layer transceiver into a single chip, allowing single-chip cost-effective solutions for broadband network designs.
Both RTL8169S and RTL8110S are compliant with IEEE 802.3, 802.3u, 802.3ab and 802.3z specifications, supporting 10, 100, and 1000Mbps data transmissions and provide NWay auto-negotiation support. The chipsets are also in compliance with Microsoft's NDIS5 (IP, TCP, UDP) Checksum and Segmentation Task-offload; IEEE 802.1p Transmit Priority Queue; and IEEE 802.1Q Virtual Bridged Local Area Network.
The architecture of the RTL8169S and RTL8110S includes a 33/66MHz, 32/64bit PCI v2.2 bus interface for host communications. Consideration is given to developers utilizing prior Realtek ICs with pin compatibility of the chips to Realtek RTL8100C, single-chip 10/100M fast Ethernet controller.
The single system design targets use in Ethernet, Fast Ethernet, or Gigabit Ethernet network functions, facilitating market segmentation or differ-entiation strategies.
Based on 0.18mm process technology, the 32bit RTL8169S-32 and RTL8110S-32 are packaged in a 128-pin QFP, while the 64bit RTL8169S-64 and RTL8110S-64 are packaged in a 233-pin TFBGA..
