O
The antenna select signal changes state as the receiver switches from antenna to antenna during the
acquisition process in the antenna diversity mode. This is a complement for ANTSEL (pin 40) for
differential drive of antenna switches.

TX_AGC_IN
18
I
Input to the transmit power A/D converter for transmit AGC control.
TX_IF_AGC
35
O
Analog drive to the transmit IF power control.
TX_PE
62
I
When active, the transmitter is configured to be operational, otherwise the transmitter is in standby
mode. TX_PE is an input from the external Media Access Controller (MAC) or network processor to
the HFA3861B. The rising edge of TX_PE will start the internal transmit state machine and the falling
edge will initiate shut down of the state machine. TX_PE envelopes the transmit data except for the
last bit. The transmitter will continue to run for 4
μ
s after TX_PE goes inactive to allow the PA to shut
down gracefully.
TXD
58
I
TXD is an input, used to transfer MAC Payload Data Unit (MPDU) data from the MAC or network
processor to the HFA3861B. The data is received serially with the LSB first. The data is clocked in the
HFA3861B at the rising edge of TXCLK.
TXCLK
55
O
TXCLK is a clock output used to receive the data on the TXD from the MAC or network processor to
the HFA3861B, synchronously. Transmit data on the TXD bus is clocked into the HFA3861B on the
rising edge. The clocking edge is also programmable to be on either phase of the clock. The rate of
the clock will be dependent upon the data rate that is programmed in the signalling field of the header.
TX_RDY
59
O
TX_RDY is an output to the external network processor indicating that Preamble and Header
information has been generated and that the HFA3861B is ready to receive the data packet from the
network processor over the TXD serial bus.
CCA
60
O
Clear Channel Assessment (CCA) is an output used to signal that the channel is clear to transmit. The
CCA may be configured to one of four possible algorithms. The CCA algorithm and its features are
described elsewhere in the data sheet.
Logic 0 = Channel is clear to transmit.
Logic 1 = Channel is NOT clear to transmit (busy).
This polarity is programmable and can be inverted.
RXD
53
O
RXD is an output to the external network processor transferring demodulated Header information and
data in a serial format. The data is sent serially with the LSB first. The data is frame aligned with
MD_RDY.
RXCLK
52
O
RXCLK is the bit clock output. This clock is used to transfer Header information and payload data
through the RXD serial bus to the network processor. This clock reflects the bit rate in use. RXCLK is
held to a logic “0” state during the CRC16 reception. RXCLK becomes active after the SFD has been
detected. Data should be sampled on the rising edge. This polarity is programmable and can be
inverted.
