CLKI duty cycle (externally driven)
Supply current
1. Typical values are at 25 °C, are for design aid only, are not guaranteed, and are not subject to production testing.
2. Limited functional tests are performed at these input levels. The majority of functional tests are performed at levels of 0 V and
Transmit output impedance
Transmit timing jitter addition
Transmit timing jitter added by the
MAU and PLS sections
Receive input impedance
Differential squelch threshold
1. Typical values are at 25 °C, are for design aid only, are not guaranteed, and are not subject to production testing.
2. Parameter is guaranteed by design; not subject to production testing.
3. IEEE 802.3 specifies maximum jitter additions at 0.5 ns from the encoder, and 3.5 ns from the MAU.
