IDT77010

The 77010 interfaces a UTOPIA PHY device to a device that uses 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 application using the IDT77010.

The UTOPIA level 1 bus interface runs at speeds up to 155 Mbps, with the DPI-4 interface capable of full duplex operation at 160 Mbps. In-stream programming is used to read and write to the PHY registers, with the Control Cells being generated from a remote controlling agent. The Control Cells are used to configure, control and retrieve status of the PHY device.
