Overshoot/Undershoot
Jitter (measured differentially)
1. Typical values are at 25°C, and are for design aid only, are not guaranteed, and are not subject to
2. Measured at the line side of the transformer, line replaced by 100 Ω (+/-1%) resistor.
Peak differential output voltage
Jitter magnitude added by the
MAU and PLS sections
Differential squelch threshold
1. Typical values are at 25°C and are for design aid only, are not guaranteed, and are not subject to
2. Parameter is guaranteed by design; not subject to production testing.
3. IEEE 802.3 specifies maximum jitter addition at 1.5 ns for the AUI cable, 0.5 ns from the encoder, and
4. After line model specified by IEEE 802.3 for 10BASE-T MAU.
