Technical Pin Function Descriptions
VDD
This is the power supply to the internal core logic of the
device as well as the clock output buffers for OUTPUT (0:9).
This pin operates at 3.3V volts. Clocks from the listed buffers
that it supplies will have a voltage swing from Ground to this
level. For the actual guaranteed high and low voltage levels
for the Clocks, please consult the DC parameter table in this
data sheet.
GND
This is the power supply ground (common or negative) return
pin for the internal core logic and all the output buffers.
OUTPUT (0:9)
These Output Clocks are use to drive Dynamic RAM’s and
are low skew copies of the CPU Clocks. The voltage swing of
the OUTPUTs output is controlled by the supply voltage
that is applied to VDD of the device, operates at 3.3 volts.
I
The SDATA and SCLOCK Inputs are use to program the
device. The clock generator is a slave-receiver device in the
I
configuration map for register functions. The I
in Philips I
followed.
BUF_IN
Input for Fanout buffers (OUTPUT 0:9).
OE
OE tristates all outputs when held low.
