AT209S 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 design complexity and increase systems stability.
PCI 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.
