VSC7323 VSC7323 Meigs-IIe - 10 x 1G and 10G Ethernet MAC Chip The VSC7323 Meigs -IIe is a versatile building block for a range of high-density Gigabit Ethernet GbE and 10 GbE applications within the Enterprise, Metro, and Core. The VSC7323 integrates 10 triple-speed MACs with integrated SerDes, a single 10 Gigabit Ethernet GbE MAC with an integrated 10 Gigabit Attachment Unit Interface XAUI , an OIF-compliant SPI-4.2 interface, a configurable parallel/serial CPU interface, and dual MII Management interface. Interfacing to the triple-speed MAC ports is accomplished using MII for 10/100 Ethernet support and RGMII/GMII for GbE support. The integrated GbE SerDes enables high density, cost-efficient per port pricing for Ethernet aggregation services. The full duplex, IEEE 802.3ae-compliant 10 GbE MAC performs pad insertion to ensure minimum frame length and CRC generation as well as preamble, SFD, and IFG insertion on transmit. On the receive side, the 10 GbE MAC performs Ethernet framing, CRC validation, and length monitoring. The VSC7323 connects seamlessly to 10 Gbps optical modules such as XENPAK, X2, and XPAK using the integrated XAUI compliant serial interface. The quad lane Gbps interface implements programmable pre-emphasis on transmit to compensate for intersymbol interference ISI and equalization on receive to ensure reliability in high loss, high distortion environments. The internal ingress Rx and egress Tx FIFOs, which are provisionable on a per port basis in increments of 2 kB, are capable of handling short-haul flow control and accommodating bursty traffic between the Ethernet MACs and the SPI-4.2 system interface. The FIFO structures are independently configurable for either cut-through or store-and- forward modes. The system side of the VSC7323, an industry standard OIF SPI-4.2 interface, is used to seamlessly transfer packet data between the VSC7323 and other devices such as network processors, SONET/SDH mappers, and customer ASICs. The 16-bit SPI-4.2 interface can transmit ingress data at MHz DDR and receive egress data in the range of 311 to 450 MHz DDR. The CPU interface can be configured as either a parallel interface for seamless connection to PowerPC and Intel microprocessors or as a simple 4-line serial interface for device initialization, control register, and per port statistic access. The VSC7323 also integrates two MII Management MIIM interfaces for managing and gathering status from the PHY devices. • Enterprise and Metro Ethernet switches • Multi-service provisioning platforms • Metro SONET/SDH transport ADMs • Edge and core aggregation routers • DWDM transport terminals Wavelength Routers SPECIFICATIONS • Implemented in low power micron CMOS technology, 2.5V/3.3V IO • Industrial Temperature Range -40ºC to +85ºC • Standard 5-Pin P1149.1 JTAG Test Port • Packaged in a 728-pin TBGA The VSC7323 is an ideal solution for OEMs designing 10 Gbps or higher solutions that require GbE and 10 GbE support.
