Electrical Characteristics (continued)
(3.15 V
≤ VCC ≤ 3.45 V, -40 °C ≤ TA ≤ 85 °C. Typical values represent most likely parametric norms at VCC = 3.3 V, TA = 25
°C, at the Recommended Operating Conditions at the time of product characterization and are not guaranteed.)

Serial Data Timing Diagram
Register programming information on the DATAuWire pin is clocked into a shift register on each rising edge of
the CLKuWire signal. On the rising edge of the LEuWire signal, the register is sent from the shift register to the
register addressed. A slew rate of at least 30 V/s is recommended for these signals. After programming is
complete the CLKuWire, DATAuWire, and LEuWire signals should be returned to a low state. If the CLKuWire or
DATAuWire lines are toggled while the VCO is in lock, as is sometimes the case when these lines are shared
with other parts, the phase noise may be degraded during this programming.
