JITTER FREQUENCY (kHz)

NOTE: THE TYPICAL PEAK JITTER GAIN OF THE DS21600/DS21602/DS21604 IS ABOUT 1.6 FOR CONVERSION FROM

T1 TO E1. THE TYPICAL PEAK-JITTER GAIN OF THE LEVEL ONE DEVICE IS ABOUT 1.1. HOWEVER, THE JITTER GAIN

FOR THE DS21600/DS21602/DS21604 PEAKS IN THE 4kHz TO 8kHz RANGE, WHEREAS THE PEAK JITTER GAIN FOR

THE LXP6XX DEVICES SPANS A GREATER FREQUENCY RANGE (20kHz TO 40kHz).
