Horizon™ GT-96100A Communications Controller
The Marvell
®
Horizon™GT-96100A communications controller is a
single-chip controller for 64-bit MIPS
®
CPUs including the PMC-
Sierra™ RM52x1A and RM7000A/B/C. This highly integrated
device contains all of the key system peripherals needed to build
a high-performance Local Area Network (LAN)/Wide Area
Network (WAN) communications system. Included in the Horizon
GT-96100A device are Multi-Protocol Serial Channels (MPSCs),
10/100 Fast Ethernet controllers and a full set of system
controller functions.
The Horizon GT-96100A device integrates the company’s
strengths in both system controllers and communications
technology. The device is extremely flexible and supports many
WAN protocols including Basic Rate ISDN, frame relay, T1/E1/T3/
E3, xDSL, HSSI, and more. With serial channel support of up to
55 Megabits (Mb) per second (Mbps) and integrated Fast
Ethernet (FE) ports, the controller is ideal for high-performance
routing, bridging and firewall applications.
