831742I Data Sheet

AC Electrical Characteristics

NOTE: Electrical parameters are guaranteed over the specified ambient operating temperature range, which is established when the device is

mounted in a test socket with maintained transverse airflow greater than 500 lfpm. The device will meet specifications after thermal equilibrium

has been reached under these conditions. Measurements performed with a PCI Express compliant input source. For additional information,

refer to the PCI Express Application Note section in the datasheet.

NOTE 1: Peak-to-Peak jitter after applying system transfer function for the Common Clock Architecture. Maximum limit for PCI Express Gen 1

NOTE 2: RMS jitter after applying the two evaluation bands to the two transfer functions defined in the Common Clock Architecture and

NOTE 3: RMS jitter after applying system transfer function for the common clock architecture. This specification is based on the PCI Express

Base Specification Revision 0.7, October 2009 and is subject to change pending the final release version of the specification.

NOTE 4: This parameter is guaranteed by characterization. Not tested in production.
