DESCRIPTION

3 interfaces and one SPI-4 interface. The data that enter on the low speed

interface (SPI-3) are mapped to logical identifiers (LIDs) and enqueued for

transmission over the high speed interface (SPI-4). The data that enter on the

high speed interface (SPI-4) are mapped to logical identifiers (LIDs) and

enqueued for transmission over a low speed interface (SPI-3). A data flow

between SPI-3 and SPI-4 interfaces is accomplished with LID maps. The logical

port addresses and number of entries in the LID maps may be dynamically

configured. Various parameters of a data flow may be configured by the user

such as buffer memory size and watermarks. In a typical application, the

IDT88P8342 enables connection of two SPI-3 devices to a SPI-4 network

processor. In other applications a SPI-3 or SPI-4 device may be connected to

a SPI-3 network processor or traffic manager.

... 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: the dual SPI-3 ingress to SPI-4 egress path, and the SPI-4 ingress to dual SPI- 3 egress path. SPI-3 and SPI-4 burst sizes are separately configurable. ...
