Device Description
(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 subsystem that includes
content inspection engines, the IDT family of NSEs delivers high-
performance, feature-rich, easy-to-use, integrated search accelerators.
synchronous full-ternary 32K 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. The device can perform Lookup and Learn NSE
operations plus Read, Write, Burst Write, and Dual Write maintenance
operations.
multiplexed address and data bus that can support 100 million sustained
searches per second. This device provides array segments which can
be configured to enable multiple width lookups from 36 to 576 bits wide.
The IDT 75P42100 requires a 1.8-volt V
or 2.5-volt V
provides the user with flexibility and control in determining 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.
CMOS processing technology and is packaged in a JEDEC Standard,
thermally enhanced, low profile Ball Grid Array. The options include a
304 BGA, satisfying smaller footprint requirements and a 372 BGA
package that is compatible with the IDT 64K x 72 Entry (75P52100) and
128K x 72 Entry (75K62100) NSE devices.

System Configurations
networking systems. In solutions requiring data searching such as
routers, a system configuration as shown in Figure 1.0 may be realized.
Maximum flexibility is provided by allowing one board design to be
populated today using either the IDT 75P42100 or 75P52100 NSEs and
later upgraded to use IDT’s 75K62100 NSE. Applications note AN-279
discusses how to accommodate one board design for any of these NSEs.
ASIC/ FPGA for lookups and routes an Index to an associated SRAM
device, which supplies the next hop address via an SRAM Data 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.
