• tERR(3 per) fall (P8) is the TIE measure at Vref (0 mV) of Z1 (differential clock signal) on only the

falling edges (negative pulses). It is set up to measure edges at intervals of 3. The minimum

value is measured as tERR(3per)fall, min reported in mUI and the maximum value is measured

as tERR(3per)fall, max reported in mUI.

• tERR(4 per) r (P9) is the TIE measure at Vref (0 mV) of Z1 (differential clock signal) on only the

rising edges (positive pulses). It is set up to measure edges at intervals of 4. The minimum value

is measured as tERR(4per)rise, min reported in mUI and the maximum value is measured as

tERR(4per)rise, max reported in mUI.

• tERR(4 per) fall (P10) is the TIE measure at Vref (0 mV) of Z1 (differential clock signal) on only the

falling edges (negative pulses). It is set up to measure edges at intervals of 4. The minimum

value is measured as tERR(4per)fall, min reported in mUI and the maximum value is measured

as tERR(4per)fall, max reported in mUI.

• tERR(5 per) r (P11) is the TIE measure at Vref (0 mV) of Z1 (differential clock signal) on only the

rising edges (positive pulses). It is set up to measure edges at intervals of 5. The minimum value

is measured as tERR(5per)rise, min reported in mUI and the maximum value is measured as

tERR(5per)rise, max reported in mUI.

• tERR(5 per) fall (P12) is the TIE measure at Vref (0 mV) of Z1 (differential clock signal) on only the

falling edges (negative pulses). It is set up to measure edges at intervals of 5. The minimum

value is measured as tERR(5per)fall, min reported in mUI and the maximum value is measured

as tERR(5per)fall, max reported in mUI.
