Dear TI Engineer,
We plan to use AFE4410 on our wearable products, with the following design:
Power supply: RX_SUP=+3V; TX-SUP=+5V; IO_SUP=1.9V (same as external MCU).
Communication: I2C, I2C_SPI_SEL is connected to a low level (Ground).
RX_SUP: Select LDO enable mode to enable the internal LDO, with Control1 connected to a low level (Ground).
CLK: Using AFE4410 internal clock, the CLK pin is connected to ground with a 510k resistor.
We also noticed from the datasheet about the design of those pins.
Can you help to confirm if our project design is okay? Or is there any better sugeestion for this design?
Thanks,
Kind Regards
