Preliminary
Information
IDT75T43100
The IDT75T43100 is designed to be used in applications that require
high speed data searching such as routers, high layer switching and
applications involved in the convergence of voice, data and video.
IDT’s IP Co-Processors (IPCs) expedite multi level routing of IP
(Internet Protocol) and includes on chip logic to facilitate various types of
IP header lookups and processing of the results.

of millions of lookups per second. IDT’s IP Co-Processor is designed to
provide a scalable solution to one of the major bottlenecks facing the
bandwidth challenge of Internet traffic.
Overview
IDT’s 75T43100 is a high performance pipelined, synchronous 32K
x72 IP Co-Processor (IPC). It utilizes content addressable memory
(CAM)technologytoperformpatternrecognitionfunctions. Eachlocation
in the IPC has both a Data entry and an associated Mask entry with the
total array size of 32K x72 Data entries and 32K x72 Mask entries.
The IDT75T43100 has a 72-bit bi-directional bus, which is a 15-bit
multiplexed address and 72-bit data bus that can support 66 million
sustained searches per second.
This device was developed for a wide range of communication and
networkingapplications,givingittheabilitytosupporttherequirementsof
multiple networks. IPC's are used in applications that require high speed
data searching routers, high layer switching and in the convergence of
voice, data, and video. IDT's IPC increases the throughput for the
demanding networking and Internet systems.
The IDT75T43100 utilizes IDT’s latest high-performance 0.18 u
CMOS processing technology and is packaged in a JEDEC Standard,
thermally enhanced, low profile, 304 Ball Grid Array (BGA).
