7.5.2 ODT DC Electrical Characteristics
A below table provides an overview of the ODT DC electrical characteristics. The values for RTT60Pd120, RTT60Pu120,
RTT120Pd240, RTT120Pu240, RTT40Pd80, RTT40Pu80, RTT30Pd60, RTT30Pu60, RTT20Pd40, RTT20Pu40 are not specifi-
cation requirements, but can be used as design guide lines:
