New Value-Priced Chip Powers
High-Speed Small Office VPNs
DSL, cable modems and other broadband
applications demand hardware security
accelerationas much as 50-100 MIPS for IPSec
processing. Now you can design in the strongest
virtual private network security without sacrificing
performance or spending big bucks.
Saves Money, Time and
Board Space
At less than $25,* our new 7951 security processor
fits within your budget and on your motherboard.
Plus, the feature-packed 7951's PCI Bus interface
reduces chip count and design time.
Soups up 3-DES and
Public Key Processing
The 7951 crunches through compression, encryption
and authentication algorithms at speeds that leave
general-purpose CPUs in the dust. And, you get a
true random number generator and Public Key
acceleration, all on the same affordable
all-purpose chip.
