Capabilities Description
Receiver interface parameter measurements
Phase Jitter
This is the jitter amplitude in unit intervals (UI) as a
function of jitter frequency.
Range 10 UI p-p from 20 Hz to 500 Hz, decreasing proportionally to 0.5 UI p-p
from 10 kHz to 50 kHz.
Accuracy
For sinusoidal jitter greater than –20 dBUI
(0.1 UI p-p) at jitter gain = 1, or greater than
–40 dBUI (0.01 UI p-p) at jitter gain = 8.
Jitter Gain = X1 or X8
50 Hz to 500 Hz ±2 dB
500 Hz to 10 kHz ±1 dB
Jitter Gain = X8
10 kHz to 50 kHz ±2 dB
Spurious Response
Jitter Gain = X1
50 Hz to 100 Hz –20 dBUI
100 Hz to 50 kHz –30 dBUI
Jitter Gain = X8
50 Hz to 100 Hz –30 dBUI
100 Hz to 50 kHz –40 dBUI
Reference input parameter measurements
Clock Rate
Range 30 kHz to 52 kHz
Accuracy ±10 ppm
Generator variable parameters
Clock Rate Range
All Inputs and Outputs 27.2 kHz to 55.2 kHz (32 kHz –15% to 48 kHz +15%)
Clock Rate Accuracy
The primary clock rates (32, 44.1, and 48 kHz) are
synthesized exactly, so accuracy depends solely on the
accuracy of the reference used (internal or external).
Internal Ref Accuracy ±10 ppm
