PRODUCTION DATA.
The JESD204B link in the device can be configured to operate in different modes using the register controls in Table 14.
REGISTER CONTROL | DESCRIPTION | ALLOWED SETTINGS |
---|---|---|
NUM_ADC_PER_LANE | Number of ADC words packed into one lane | 2, 4, 8 |
ADC_RES | Number of bits resolution in the ADC word input to the JESD transmitter block | 10, 12, 14, 16 |
SER_DATA_RATE | Serialization factor control | 10, 12, 14, 16 |
In addition to the register controls mentioned in Table 14, the SING_CONV_PER_OCT register bit controls the packaging efficiency of the ADC data into octets.
The link configuration parameters are determined by Table 15.
