7. Component Availability and Ordering Information
8. Glossary
CLOCK:
A single differential input used to gate data into registers in the Output Buffer. The input serves all
outputs of the OCX. The neighbor input can also be used as a register clock.
CROSSPOINT:
A single cell controlled by two RAM bits. The RAM bits are connected in a master-slave
configuration to provide an update for programming and changing program information all at once.
CROSSPOINT ARRAY:
An array of Crosspoint cells used to connect any input port to any output port.
INPUT OR OUTPUT PATH:
The signal flow from pin to array and array to pin. Each path has a register with
selectable clocks, drivers for the loaded outputs with selectable enables, and sense circuits to detect changes on
either side of the IO Buffer.
NEXT NEIGHBOR:
A physically adjacent port can be used as a clock source for an output configured in
registered mode. These outputs are grouped in pairs such that the signal being switched through Output 0 can be
used to clock the signal being switched through Output 1, or vice-versa. Any single clock or data input signal
can be used to clock any other input signal provided they are switched to an appropriate output pair.
PORT:
A name followed by a number to identify a pin on the device.
RAPIDCONFIGURE:
A parallel programming method for the OCX devices. The RC mode uses 25 dedicated
pins to program the Crosspoint Array and the IO Buffers. The 25 pins consist of an enable, a clock, four
instruction bits, two seven-bit address fields, and a five-bit data field.
