Description: With the FS2221, designers can use their Agilent logic analyzer as a passive AGP 4X analyzer. The FuturePlus Transaction Inverse Assembler, coupled with the advanced triggering and system performance software of Agilent's logic analyzers, give the user a powerful tool in debugging, testing, and verifying compliance of PC's and workstations incorporating the AGP4X in the graphics system.
The FS2221 probe board plugs into an AGP4X socket. Four coax cables attach the probe board to the FS2221, with three cables carrying the 4X signals and one cable carrying the 1X signals. Specially selected series resistors are used to isolate the probe from the AGP. Since the AGP is a series-terminated bus, it is essential that designers keep the end-to-end AGP channel length less than 6" to insure proper capture of all transactions.
With the AGP4X transferring data at 266 MHz, the minimum setup and hold time is 1.1 ns. Since the AGP4X is series terminated, data is monitored at the receivers. The FS2221 is a conventional "interposer" design that plugs into the AGP connector in series with the AGP graphics card. The FS2221 can monitor the AGP in all three modes of operation, 1X, 2X and 4X. The AGP has 32 bits of Address/Data, 4 bits of Command/Byte Enables, 8 bits of sideband data, and 15 bits of control (1X clock). The strobed signals are valid on both edges. The strobe frequency is 133 MHz in 4X mode, and 66 MHz in 2X/1X mode. The 1X clock frequency is 66 MHz.
This unit has the following features:
Quick and easy connection between the AGP socket and Agilent Logic Analyzers
