Output
Radio power down enable is an active low signal used for power
management purposes for the radio circuitry.
Input
This is an input from baseband processor. It is used to clock in received
data from baseband processor.
Input
Receive data ready is an input signal from the baseband processor,
indicating a data packet is ready to be transferred to the MAC. The signal
returns to inactive state when there is no more receiver data or when the
link has been interrupted. This signal is sampled on the falling edge of
RXCLK (in 3824 mode), and sampled at rising edge of RXCLK (in 3860B
mode).
Input
Receive data is an input from the baseband processor transferring
demodulated header information and data in a serial format. The data is
frame aligned with MD_RDY. This signal is sampled on the falling edge of
RXCLK (in 3824 mode), and sampled at rising edge of RXCLK (in 3860B
mode).
Input
Analog power for DAC. 3.3V input.
Input
Analog ground for DAC.
Output
Radio link quality based on packet error rate. Active low implies the
packet was received without errors. Note: Lost packets are not detected.
