Bit | Field | Type | Reset | Description |
---|---|---|---|---|
15 | 0 | R/W | 0h | Must write 0 |
14 | LVDS_RATE_2X | R/W | 0h | 0 = 1X rate; normal operation (default)
1 = 2X rate. This setting combines the data of two LVDS pairs into a single LVDS pair. This feature can be used when the ADC clock rate is low. |
13-8 | 0 | R/W | 0h | Must write 0 |
7 | SEL_CH[2] | R/W | 0h | Input mode selection bit 3. Table 49 lists bit settings for the three input modes. |
6 | EN_JESD | R/W | 0h | 0 = JESD interface disabled
1 = JESD interface enabled; see Table 49 |
5 | DIS_LVDS | R/W | 0h | 0 = LVDS interface is enabled (default)
1 = LVDS interface is disabled |
4 | SEL_CH[1] | R/W | 0h | Input mode selection bit 2. Table 49 lists bit settings for the three input modes. |
3 | 0 | R/W | 0h | Must write 0 |
2 | SEL_CH[0] | R/W | 0h | Input mode selection bit 1. Table 49 lists bit settings for the three input modes. |
1 | 0 | R/W | 0h | Must write 0 |
0 | GLOBAL_PDN | R/W | 0h | 0 = The device operates in normal mode (default)
1 = ADC enters complete power-down mode |
