TI provides a recommended PCB layout in the AFE1230E/1K evaluation module documentation, which includes guidelines for component placement, routing, and grounding to minimize noise and ensure optimal performance.
The AFE1230E/1K clock frequency can be configured using the CLK_CFG register. Refer to the device's programming guide for specific register settings and clock frequency options.
The maximum input voltage range for the ADC is ±VREF, where VREF is the reference voltage, which can be set to 1.2V, 2.5V, or 4.096V using the VREF_CFG register.
The AFE1230E/1K has built-in digital filters and decimators. Configure the FILT_CFG and DEC_CFG registers to select the desired filter type, cutoff frequency, and decimation ratio. Refer to the device's programming guide for specific register settings.
The ADC conversion latency is approximately 1.5 clock cycles, which corresponds to 30 ns at a 50 MHz clock frequency. This latency can be affected by the selected ADC mode and clock frequency.
