DSI
O
Clock Jitter (Advanced Master Clock required)
Jitter Measurement
Range 0 to 650 ns
Detection Peak, RMS, or Average “Average” detection is recommended
for jitter response measurements.
Bandwidth
Low Limit 50 Hz or 700 Hz
High Limit Variable from 1 kHz to 150 kHz in
0.1 kHz steps, Butterworth or Elliptic
response
Accuracy (1 kHz) ±(1% + 300 ps) “Average” detection
Flatness
1
±0.2 dB, 100 Hz to 100 kHz
Residual Jitter
1
700 Hz to 100 kHz BW ≤ 600 ps
Jitter Spectrum

Spurious products are typically
–40 dBc (below jitter signal) or
–60 dBUI, whichever is larger.
