AC Electrical Characteristics (Continued)

Note 2: Current flow into device pins is defined as positive. Current flow out of device pins is defined as negative. All voltages are referenced to VSSIO =VSSD =

VSSSI =0V.

Note 3: Typical values are stated for VDDIO =VDDSI = +3.3V, VDDD =VDDPLL = +2.5V and TA = +25˚C.

Note 4: Spec. is guaranteed by design.

Note 5: Measured from rising-edge of first SDI cycle until Lock Detect bit goes high (true). Lock time includes CDR phase acquisition time plus PLL lock time.

Note 6: VOHV and VOLP are measured with respect to reference ground. VOLP is the peak output LOW voltage or ground bounce that may occur under dynamic

simultaneous output switching conditions. VOHV is the lowest output HIGH voltage or output droop that may occur under dynamic simultaneous output switching

conditions.

Note 7: When used to clock control data into or from the CLC031A, the duty cycle restriction does not apply.

Note 8: IIH includes static current required by input pull-down devices.

Note 9: Required Input Conditions are the electrical signal conditions or component values which shall be supplied by the circuit in which this device is used in order

for it to produce the specified DC and AC electrical output characteristics.

Note 10: Functional and certain other parametric tests utilize a CLC030 as the input source to the SDI inputs of the CLC031A. The CLC030 is DC coupled to the

inputs of the CLC031A. Typical VIN = 800 mV, VCM = 2.9 V.
