API PROGRAMMING
The ADRV9001 SSI configuration is performed in chip initialization stage and based on the following data structure.
typedef struct adi_adrv9001_SsiConfig
{
adi_adrv9001_SsiType_e ssiType;
adi_adrv9001_SsiDataFormat_e ssiDataFormatSel;
adi_adrv9001_SsiNumLane_e numLaneSel;
adi_adrv9001_SsiStrobeType_e strobeType;
uint8_t lsbFirst;
uint8_t qFirst;
bool refClockGpioEn;
uint8_t lvdsBitInversion;
uint8_t lvdsUseLsbIn12bitMode;
bool lvdsTxFullRefClkEn;
bool lvdsRxClkInversionEn;
uint32_t rfLvdsDiv;
bool cmosTxDdrNegStrobeEn;
bool cmosDdrPosClkEn;
bool cmosDdrClkInversionEn;
bool cmosDdrEn;
} adi_adrv9001_SsiConfig_t;
In the data structure, the previously mentioned SSI modes are defined for each Tx/RX channel, users can find the detail data structure
and enumerator description in API doxygen help file.
A set of API commands are provided to set and inspect the SSI test/debug functions, which are summarized in Table 20.
Table 20. SSI Test/Debug API List
