8.4.1. XCVR_A10_RX_LINK
Pin planner or Assignment Editor Name
Receiver Link Type
Description
This parameter is configured depending on the link characteristic. Value SR is used for link insertion loss less than equal to 10dB and value LR is used for link insertion loss greater than 10dB. If this QSF assignment is not done, Quartus Prime assigns SR as the default value. Settings dependent on this parameter value are DC gain, VGA and sd_threshold for SATA. This is also used for data rate legality check during compilation.
For SR: sd_threshold for SATA = SDLV_4
For LR: sd_threshold for SATA = SDLV_6
For the default values of DC gain and VGA corresponding to RX_LINK setting, look for QSF assignments XCVR_A10_RX_EQ_DC_GAIN_TRIM and XCVR_A10_RX_ADP_VGA_SEL.
