Note 1: “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur, including inoperability and degradation of device reliability
and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or other conditions beyond those indicated in
the Recommended Operating Conditions is not implied. The Recommended Operating Conditions indicate conditions at which the device is functional and the
device should not be operated beyond such conditions.
Note 2: 4L =4 layer PCB per JEDEC specification, 2L = 2 layer PCB per JEDEC specification.
Note 3: The Electrical Characteristics tables list guaranteed specifications under the listed Recommended Operating Conditions except as otherwise modified
or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and are not guaranteed.
Note 4: Typical values represent most likely parametric norms at V
product characterization and are not guaranteed.
Note 5: Current into device pins is defined as positive. Current out of a device pin is defined as negative. Voltages are referenced to ground except VOD, ΔVOD,
VTH and VTL which are differential voltages.
Note 6: When the Serializer output is at TRI-STATE the Deserializer will lose PLL lock. Resynchronization MUST occur before data transfer.
Note 7: t
Note 8: RxIN_TOL is a measure of how much phase noise (jitter) the Deserializer can tolerate in the incoming data stream before bit errors occur. It is a
measurement in reference with the ideal bit position, please see National’s AN-1217 for detail.
Note 9: Specification is guaranteed by characterization and is not tested in production.
Note 10: t
