Device Description
The NSE Quad XSC interface is intended to work with any AMCC NPU
with an external search co-processor interface (XSC). It will operate with
multiple NPUs such as the nP3400 and nP7250, or can be used to satisfy
the four XSC requirements of the nP7510. The 75K52413 is compliant with
the XSC specification and the device may be optionally expanded up to
eight devices deep providing 1 million entries of 32-bit width.
