NOTE: THE TYPICAL PEAK JITTER GAIN OF THE DS21610 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
DS21610 PEAKS IN THE 4kHz TO 8kHz RANGE, WHEREAS THE PEAK JITTER GAIN FOR THE LXP610 SPANS A
GREATER FREQUENCY RANGE (20kHz TO 40kHz).
