ZHCSEA4C May 2015 – December 2020 ADS54J40
PRODUCTION DATA
The ADS54J40 provides a fast overrange indication that can be presented in the digital output data stream via SPI configuration. Alternatively, if not used, the SDOUT (pin 11) and PDN (pin 50) pins can be configured through the SPI to output the fast OVR indicator.
JESD 8b/10b encoder receives 16-bit data that is formed by 14-bit ADC data padded with two 0s as LSBs. When the FOVR indication is embedded in the output data stream, it replaces the LSB of the 16-bit data stream going to the 8b/10b encoder, as shown in Figure 8-10.
