CellBus Bus Acknowledge: Active low
acknowledge.
CellBus Bus Congestion Indicator: Active
low congestion indicator.
CellBus Bus Data: Active low 32-bit parallel
data input/output bus.
CellBus Bus Frame: 16-clock cycle structure.
CellBus Bus Read Clock: Accepts data from
bus. Falling edge used for data transfer.
CellBus Bus Write Clock: Puts data on the
bus. Falling edge used for data transfer.
CellBus Bus Congestion: If EBP=1, indicates
congestion or impending congestion detected
after the CUBIT- Pro sends a cell to the CellBus
bus. This indication is provided in UTOPIA,
16-Bit and Back-to-Back Modes. If EBP=0 this
signal is a GTL-to-CMOS translation of CellBus
bus signal CBCONG.
CellBus Bus Disable: Active low signal to tri-
state the entire CellBus bus regardless of the
state of the V
(This signal is not part of the CellBus bus.)
VREF: Reference voltage for GTL receivers.
VREF is approximately 2/3 V
backplane termination voltage (nominally Vtt =
+1.2V). The input connection to this pin is not
part of the CellBus bus.
