IDT88P8342 SPI EXCHANGE 2 x SPI-3 TO SPI-4
INDUSTRIALTEMPERATURERANGE
APRIL 10, 2006
TYPICAL APPLICATION
Exchange between optical ports and two NPU/Traffic Managers
1. INTRODUCTION
The IDT88P8342 device is a dual SPI-3 to single SPI-4 exchange
intended for use in optical line cards, Ethernet transport, and multi-service
switches. The SPI-3 and SPI-4 interfaces are defined by the Optical
Interworking Forum.
The device can be used as a rate adapter, a switch, or an aggregation
devicebetweennetworkprocessorunits,multi-gigabitframersandPHYs,and
switch fabric interface devices.
DATA PATH OVERVIEW
Figure 1. Data Path Diagram shows an overview of the data path through
the device.
In normal operation, there are two paths through the IDT88P8342 device:
thedualSPI-3ingresstoSPI-4egresspath,andtheSPI-4ingresstodualSPI-
3 egress path. SPI-3 and SPI-4 burst sizes are separately configurable.
In the SPI-3 ingress to SPI-4 egress path, data enter in fragments on the SPI-
3 interface and are received by the SPI-3 interface block. The fragments are
mapped to a SPI-4 address and stored in memory allocated at the SPI-3 level
untilsuchatimethatthePacketFragmentProcessordeterminesthattheyareto

the OIF SPI-4 implementation agreement, to the SPI-4 interface block, and are
transmitted on the SPI-4 interface.
In the SPI-4 ingress to SPI-3 egress path, data enter in bursts on the SPI-4
interface and are received by the SPI-4 interface block. The SPI-4 address is
translated to a SPI-3 address, and the data contained in the bursts are stored
inmemoryallocatedattheSPI-3leveluntilsuchatimethatthePacketFragment
