nrf5240 i2s

HI

1. If we choose a 28.8MHz crystal oscillator for the MCLK of I2S, will it affect BT?
2. In our design, the power supply is VBAT, and the VDD_nRF setting is 1.8V. Does it affect the RF power of BT?

Thanks!

Hi

1. I'm unsure whether you should choose a 28.8MHz crystal oscillator for your I2S, I guess that depends on the I2S device, but it should not affect the radio or Bluetooth performance.

2. As long as the battery is not mounted very close to the antenna there shouldn't be any degradation in RF performance due to the battery either.

Best regards,

Simon
