The ADM8515/X, USB based chip set, provides desktop, notebook and computer peripheral with greater
connectivity and data-transmission to Ethernet and home network. The ADM8515X is the environmentally friendly
“green” package version.
The ADM8515/X device combines USB2.0 transceiver with UTMI interface, an EP decoder used for USB interface
through Parallel Interface Engine (PIE), FIFO controller with 24K SRAM, 64 byte and 2K byte buffers,
10/100 Mbit/s Ethernet physical layer (PHY) and MII interface.
It is capable of providing an easy, universal connectivity to computer peripherals with USB. The transfer rate of
USB interface is 480 Mbit/s belonging to a high speed USB device. The ADM8515/X supports all USB commands,
4 endpoints and suspend/resume function.
The ADM8515/X’s LAN PHY supports 100 Base TX (100 Mbit/s mode) and 10 Base T (10 Mbit/s mode) full-duplex
operations. It uses the auto-negotiation function to optimize the network traffic and the built-in 24K bytes SRAM
for receiving buffer, especially for 100 Mbit/s. Through FIFO controller, data can communicate in fluently between
buffers and external device. To obtain the better signal quality, the PHY provides wave-shaper, filter and adaptive
equalizer to reach. By using diagnostic mechanism (loop-back mode), the data correctness will be increased. The
LAN PHY supports external transmit/receive transformer turn ratio 1:1. The ADM8515/X chip set can be
programmed for MAC analysis and provides MII interface for external PHY, such as MII interface for HomePNA
and Homeplug. In system application, EEPROM is essential in that it needs to load device ID, vendor ID
automatically. So for ADM8515/X, serial interface is applied for EEPROM communication including read/write
function. Furthermore, some LED pins report system statuses. Infineon-ADMtek provides an EEPROM Access
Program utility for programming vendor ID, Product ID Etc.
ADM8515/X is ideally suited for USB adapter and intelligent networked peripheral design. It can also be used in
Wide Area Network (WAN), such as xDSL, Cable Modem, router, and Information Appliance (IA) application etc.
