Note 4: 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 5: See section 3.2 for more current consumption / power dissipation calculation information.
Note 6: For all frequencies the slew rate, SLEW
Note 7: The noise floor of the divider is measured as the far out phase noise of the divider. Typically this offset is 40 MHz, but for lower frequencies this
measurement offset can be as low as 5 MHz due to measurement equipment limitations. If the delay is used, then use section 1.3.
Note 8: Specification is guaranteed by characterization and is not tested in production.
Note 9: See characterization plots to see how this parameter varies over frequency.
Note 10: Applies to GOE, LD, and SYNC*.
Note 11: Applies to CLKuWire, DATAuWire, and LEuWire.
Serial Data Timing Diagram
Data bits set on the DATAuWire signal are clocked into a shift register, MSB first, on each rising edge of the CLKuWire signal. On
the rising edge of the LEuWire signal, the data is sent from the shift register to the addressed register determined by the LSB bits.
After the programming is complete the CLKuWire, DATAuWire, and LEuWire signals should be returned to a low state. The slew
rate of CLKuWire, DatauWire, and LEuWire should be at least 30 V/µs.
