Desc ription
The77010interfaces aUTOPIAPHY devicetoadevicethatuses a
Data Path Interface (DPI). Examples of PHY devices may include the
IDT77105, and the IDT77V400 Switching Memory is an example of a
component that utilizes a DPI interface. Figure 1 illustrates a typical
applicationusingtheIDT77010.
The UTOPIA level 1 bus interface runs at speeds upto155 Mbps,
withtheDPI-4interfacecapableoffullduplexoperationat160Mbps.
In-streamprogrammng is usedtoreadandwrite tothe PHY regis-
ters, with the Control Cells being generated froma remote controlling
agent. The Control Cells are used to configure, control and retrieve
statusofthePHY device.

Control cells are insertedanddecodedby the control cell decoder.
The control cells are filteredandwill notbe transferredtothe UTOPIA

command cell, the Utility bus does a one byte write to the specified
Utility bus address. Fora Utility bus readcommandcell, the Utility bus

A status cell is a complete ATMcell generated and loaded to the
ReceiveDPI-4I/F logic.
