sync: In sync mode, the internal clock is disabled and the frequency |
|
of the external clock signal establishes therate of data |
|
collection and processing. See Fig 14 and 15 in the datasheet. |
|
The clock-frequency must be: |
|
* 3000 to 4500 Hz for adis1649x devices. |
|
* 700 to 2400 Hz for adis1648x devices. |
|
pps: In Pulse Per Second (PPS) Mode, the rate of data collection and |
|
production is equal to the product of the external clock |
|
frequency and the scale factor in the SYNC_SCALE register, see |
|
Table 154 in the datasheet. |
|
The clock-frequency must be: |
|
* 1 to 128 Hz for adis1649x devices. |
|
* This mode is not supported by adis1648x devices. |

|
The DIOx line to be used as an external clock input. |
|
Each DIOx pin supports only one function at a time (data ready line |
|
selection or external clock input). When a single pin has two |
|
two assignments, the enable bit for the lower priority function |
|
automatically resets to zero (disabling the lower priority function). |
|
Data ready has highest priority. |
|
If not provided then DIO2 is assigned as default external clock |
|
input pin. |
