Description

External TX PA and RX LNA delay configuration

Fields

LNA_CTL_DELAY

The delay used to assert LNA_CTL, LNA_tRamp micro-seconds, ahead of first bit of the expected rx_data, which can be used to turn on the external Low Noise Amplifier. The value to be programmed to the lna_ctl_delay [7:0] = rx_on_delay - LNA_tRamp rx_on_delay[7:0] = TX_RX_ON_DELAY[7:0]) LNA_tRamp = External Low Noise Amplifier startup time

PA_CTL_DELAY

The delay used to assert PA_CTL exactly PA_tRamp micro-seconds ahead of the first bit of the tx_data, which can be used to turn on the external power amplifier. The value to be programmed to the pa_ctl_delay [7:0] = tx_on_delay - PA_tRamp tx_on_delay[7:0] = TX_RX_ON_DELAY[15:8]) PA_tRamp = External Power Amplifier ramp time
