1
Measured into fixed 2pF load cap. Input to output skew is measured at the first output edge following the corresponding input.
2
Measured from differential cross-point to differential cross-point. This parameter can be tuned with external feedback path, if present.
3
All Bypass Mode input-to-output specs refer to the timing between an input edge and the specific output edge created by it.
4
This parameter is deterministic for a given device.
5
Measured with scope averaging on to find mean value.
6
This value is programmable.
7
Measured as maximum pass band gain. At frequencies within the loop BW, highest point of magnification is called PLL jitter peaking.
8
Guaranteed by design and characterization, not 100% tested in production.
9
Measured at 3db down or half power point.
10
Duty cycle distortion is the difference in duty cycle between the output and the input clock when the device is operated in Bypass
Mode.
11
Measured from differential waveform.
1
Guaranteed by design and characterization, not 100% tested in production.
2
Measured from differential waveform.
3
Slew rate is measured through the V
SWING
voltage range centered around differential 0 V. This results in a ±150mV window around
differential 0V.
4
Matching applies to rising edge rate for Clock and falling edge rate for Clock#. It is measured using a ±75mV window centered on the
average cross point where Clock rising meets Clock# falling. The median cross point is used to calculate the voltage thresholds the
oscilloscope is to use for the edge rate calculations.
5
V
CROSS
is defined as voltage where Clock = Clock# measured on a component test board and only applies to the differential rising
edge (i.e. Clock rising and Clock# falling).
6
The total variation of all V
CROSS
measurements in any particular system. Note that this is a subset of V
CROSS_MIN/MAX
(V
CROSS
absolute) allowed. The intent is to limit V
CROSS
induced modulation by setting Δ-V
CROSS
to be smaller than V
CROSS
absolute.
7
At default SMBus settings.
8
If driving a receiver with input terminations, the V
MAX
and V
MIN
values will be halved.
