AME, Inc.
AT209S
n General Description
The AT209S is an integrated device that contains a PCI
Arbiter and a Clock Buffer. PCI Arbiter extends system
PCI devices without piecing other circuit to simplify de-
sign complexity and increase systems stability.
www.DataSheet4UP.cComI Arbiter also provides STOP# input pin with that
extended PCI devices instruct the master to prematurely
end the transaction on the current data phase same as
one in PCI specification.
Clock Buffer is a high performance and low jitter zero
delay buffer that provides synchronization between the
input and output. The synchronization is established via
CLKO feed back to the input of a build-in PLL.
PCICLKI is the clock input of the Clock Buffer. In the
absence of PCICLKI input, will be in the power down mode.
In this mode, the PLL is turned off and the output buffers
are pulled low. Power down mode provides the lowest
power consumption for a standby condition.
