... IP services equipment DESCRIPTION The IDT88P8342 is a SPI (System Packet Interface) Exchange with two SPI- 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) ...

... 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. ...
