Notes to Table 1–14:
(1) For an explanation of terms used in Table 1–14, refer to “Glossary” on page 1–27.
(2) VTT of transmitting device must track VREF of the receiving device.
(3) Value shown refers to DC input reference voltage, VREF(DC).
(4) Value shown refers to AC input reference voltage, VREF(AC).
