38 / 97 page  GS12281 Final Data Sheet Rev.9 PDS-061385 February 2019 38 of 97 Semtech Proprietary & Confidential www.semtech.com 4.7 Output Drivers The GS12281 features two independently configurable output drivers (see Figure 3-2), with data (re-timed or bypassed) available on both outputs. The two drivers provide highly configurable amplitude and pre-emphasis control. The signal on the outputs can be inverted to help with signal polarity when layout requires trace inversion. The PRBS generator is available on both outputs. The LOS (Loss of Signal) status from the equalizer stage can be used to automatically mute or disable the outputs on their assertion. The Loss of Lock status from the CDR block can be used to mute the outputs. The cable drivers can be configured to mute or disable during sleep. The sleep control modes takes precedence over the manual or automatic LOS and Loss of Lock output control modes. Note: The <n> in the control parameter names refers to the output number. Output 0 is the cable driver output SDO0/SDO0 and output 1 is the cable driver output SDO1/SDO1. 4A, CONTROL_ OUTPUT_ DISABLE CTRL_OUTPUT1_AUTO_DISABLE Selects automatic or manual disable control for SDO1/SDO1. CTRL_OUTPUT1_MANUAL_DISABLE Manually set the disable control of the SDO1/SDO1 when auto disable mode is turned off. CTRL_OUTPUT0_AUTO_DISABLE Selects automatic or manual disable control for SDO0/SDO0. CTRL_OUTPUT0_MANUAL_DISABLE Manually set the disable control of the SDO0/SDO0 when auto disable mode is turned off. 4B, CONTROL_ OUTPUT_ SLEW CTRL_OUTPUT0_AUTO_SLEW Selects auto or manual slew rate selection for SDO0/SDO0. CTRL_OUTPUT0_MANUAL_SLEW Manually set the slew rate for SDO0/SDO0 when auto slew mode is turned off. CTRL_OUTPUT1_AUTO_SLEW Selects auto or manual slew rate selection for SDO1/SDO1. CTRL_OUTPUT1_MANUAL_SLEW Manually set the slew rate for SDO1/SDO1 when auto slew mode is turned off. 52, PRBS_GEN_ CTRL CTRL_PRBS_GEN_SIGNAL_SELECT Selects between setting the output of the PRBS generator to being a clock or a PRBS test signal. CTRL_PRBS_GEN_CLK_SRC Selects the clock source used by the PRBS generator. CTRL_PRBS_GEN_CLK_DIVIDER If a clock is selected as the PRBS output signal, this parameter sets the divide ratio of the clock. CTRL_PRBS_GEN_INVERT Allows the polarity of the PRBS signal to be inverted. CTRL_PRBS_GEN_DATA_RATE If a PRBS test signal is selected as the output signal, this parameter sets the data rate of the PRBS7 signal. CTRL_PRBS_GEN_ENABLE Used to enable or disable the PRBS generator. Table 4-7: PRBS Generator Parameter Descriptions (Continued) Register Addressh and Name Parameter Name Description |
