9.8.1 ODT DC electrical characteristics
Table 26 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:
[ Table 25 ] ODT DC Electrical characteristics, assuming RZQ=240 ohm +/- 1% entire operationg temperature range ;
after proper ZQ calibration.
