VME-PMC-CADDY

VME-PCI Link
The VMEbus unit PMC-CADDY is a VME64- base board which can carry up to two PMC
modules of normal size or one module of double size.
For the VMEbus connection the VME-PCI bridge UNIVERSE CA91C142 by Tundra with an internal clock rate of 33 MHz is used.
VMEbus Interface
The CA91C142 is designed in a way that the board can either operate as slave or as
master on the VMEbus. If the board operates as master, it supports a 4-level arbiter. The PMC-CADDY operates with a
data width of up to 32 bits and with 32 address signals on the VMEbus. The VMEbus interrupt can be applied to any of
the seven interrupt-request lines. The board is connected to the VMEbus by two 160-pin
VG-connectors according to IEC603-xx on VME64 extensions.
An active VMEbus-interrupt request is shown by a red LED in the front panel and a VMEbus access onto the board is shown by
a yellow LED.
PMC Plug-In Units
Both PMC plug-in units are designed according to the draft standard IEEE
P1386/Draft 2.0 (except the standard I/O pin routing). It is possible therefore to insert all
PMC modules which are on the market, that can handle 5 V signaling on PCI bus.
