Transceivers
The transceivers consist of Texas Instruments SN74ALVC16268 bidirectional registered 12-bit-to-24-bit bus
exchangers with tri-state outputs.
The transceivers transfer data bidirectionally between the 72-bit UltraSPARC-IIi memory data bus, and the
144-bit DIMM memory data bus. The DIMMs are cycled in EDO mode according to the memory controller
programming.
The transceiver has bus-hold on data inputs, eliminating the need for external pullup resistors. It is available
in 56-pin Plastic Shrink Small-Outline (DL) and Thin Shrink Small-Outline (DGG) packages.
The ports connected to the DIMMs include the equivalent of 26
series resistors, to make external series ter-
mination resistors unnecessary on this side. Termination is not necessary on the CPU side with short bus
lengths and minimum loading.
The device provides synchronous data exchange between the two ports. Data is stored in the internal registers
on the low-to-high transition of the CLK input, provided that the appropriate CLKEN inputs are low. All con-
trol inputs, including the CLK inputs, are driven by the UltraSPARC-IIi CPU.
Reset/Interrupt/Clock Controller (RIC) Chip
The RIC Chip (SME2210) supports the system resets, system interrupts, system scan, and system clock control
functions. Its features include:
Support for resets from power supply, reset buttons, and scan
Concentration of the interrupts; it sends interrupt numbers to the UltraSPARC-IIi CPU
