9.8.1 ODT DC Electrical Characteristics

Table 25 provides and overview of the ODT DC electrical characteristics. They values for RTT60pd120, RTT60pu120, RTT120pd240, RTT120pu240, RTT40pd80,

RTT40pu80, RTT30pd60, RTT30pu60, RTT20pd40, RTT20pu40 are not specification requirements, but can be used as design guide lines:
