NRPD

Output

Radio power down enable is an active low signal used for power

management purposes for the radio circuitry.

RXCLK

Input

This is an input from baseband processor. It is used to clock in received

data from baseband processor.

MDRDY

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).

RXD

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).

DACAVCC

Input

Analog power for DAC. 3.3V input.

DACAGND

Input

Analog ground for DAC.

RLQ

Output

Radio link quality based on packet error rate.

Active low implies the

packet was received without errors. Note: Lost packets are not detected.
