ICS74001I-05 Data Sheet

PCI EXPRESS™ JITTER ATTENUATOR

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.

NOTE 1: This parameter is defined in accordance with JEDEC Standard 65.

NOTE 2: Peak-to-Peak jitter after applying system transfer function for the Common Clock Architecture. Maximum limit for PCI Express Gen 1

NOTE 3: RMS jitter after applying the two evaluation bands to the two transfer functions defined in the Common Clock Architecture and

NOTE 4: Guaranteed only when input clock source is PCI Express and PCI Express Gen 2 compliant.
