78Q8430 Data Sheet
4.5.3
4.5.4
Note: The Manchester-encoded data pulses, the link pulse and the start-of-idle pulse are tested against
the templates and using the procedures found in Clause 14 of IEEE 802.3. Measured at the line side of
the transformer. Test Condition: Transformer P/N: TLA-6T103. Line Termination: 100 Ω ± 1%
4.5.5
Note: The specifications in the preceding table are included for information only. They are mainly a
function of the external transformer and termination resistors used for measurements
