75K62100
Device Description
IDT provides proven, industry-leading network search engines
(NSEs) and a comprehensive suite of software that enable and accelerate
the intelligent processing of network services in communications equip-
ment. As a part of the complete IDT classification subsystemthat includes
content inspection engines, the IDT famly of NSEs delivers high-
performance, feature-rich, easy-to-use, integrated search accelerators.
The IDT 75K62100 NSE is a high performance pipelined low-power,
synchronous full-ternary 128K x 72 entry device. Each entry location in
the NSE has both a Data entry and an associated Mask entry. The NSE
devices integrate content addressable memory (CAM) technology with
high-performance logic. They can performLookup and Learn NSE
operations plus Read, Write, Burst Write, and Dual Write maintenance
operations.
The IDT 75K62100 NSE device has a bi-directional bus that is a
multiplexed address and data bus that can support 100 mllion sustained
searches per second. This device provides array segments which can
be configured to enable multiple width lookups from36 to 576 bits wide.
The IDT 75K62100 requires a 1.2-volt V
DD
supply and a 2.5-volt V
DDQ
supply. This NSE device provides the user with flexibility and control in
determning the device power. Only the array segments that will be used
for a specific NSE operation are powered up while the unused segments
are not.
The IDT 75K62100 utilizes the latest high-performance 1.2V CMOS
processing technology and is packaged in a JEDEC Standard, thermally
enhanced, low profile Ball Grid Array. The IDT 372 BGA package
provides increased heat transfer for thermally challenged systems. The
372 BGA footprint is backwards compatible with the IDT 64K x 72 Entry
(75P52100) and 32K x 72 Entry (75P42100) NSE devices.

System Configurations
The IDT NSEs are designed to fulfill the needs of various types of
networking systems. In solutions requiring data searching such as
routers, a systemconfiguration as shown in Figure 1.0 may be realized.
Maximumflexibility is provided by allowing one board design to be
populated today using either the IDT 75P42100 or 75P52100 NSEs and
later upgraded to use the IDT 75K62100 NSE. Applications note AN-279
discusses how to accommodate one board design for any of these NSEs.
In this compatible configuration, the NSE interfaces directly to an
ASIC/ FPGA for lookups and routes an Index to an associated SRAM
device, which supplies the next hop address via an SRAMData Bus to
the ASIC. The NSE provides the required control signals to directly
hookup to ZBT or Synchronous Pipeline Burst SRAM Lookup results
can also be fed directly back to the ASIC/ FPGA without the use of external
SRAM. Control of the associated handshake signals is provided by all
NSEs to adapt to either configuration.
