1.1 DEVICE DESCRIPTION
The Envoy
class networks. The Envoy-CE2 incorporates two configurable Media Access Controllers
(MACs). Each MAC can be configured as a single Gigabit Ethernet (10/100/1000 Mbit/s), dual
Fast Ethernet with extended buffers or octal Fast Ethernet (10/100 Mbit/s) interface and is
programmable for either full-duplex or half-duplex operation. The Envoy-CE2 supports Super
Jumbo (12 KBytes) packets on both Fast Ethernet and Gigabit Ethernet interfaces.
The Envoy-CE2 is designed to interface directly with SPI-3 compliant devices, such as
network processors. The support for master mode on the SPI-3 allows glueless interface with
standard SPI-3 based GFP/VCAT framers and mappers. On the Ethernet side, the Envoy-CE2
interfaces directly with standard Fast Ethernet and Gigabit Ethernet PHY/SerDes devices via
the SMII and GMII. The Envoy-CE2 incorporates on-chip buffering to promote high
performance without congestion or loss of data and provides backpressure support on both
the Ethernet and SPI-3 interfaces.
