PRODUCT SPECIFICATION
nRF2401A Single Chip 2.4 GHz Radio Transceiver
DuoCeiver Simultaneous Two Channel Receive Mode
In both ShockBurst & direct modes the nRF2401A can facilitate simultaneous
reception of two parallel independent frequency channels at the maximum data rate.
This means:
nRF2401A can receive data from two 1 Mbps transmitters (ex: nRF2401A
or nRF2402) 8 MHz (8 frequency channels) apart through one antenna
interface.
The output from the two data channels is fed to two separate MCU
interfaces.
Data channel 1: CLK1, DATA, and DR1
Data channel 2: CLK2, DOUT2, and DR2
DR1 and DR2 are available only in ShockBurst.
The nRF2401A DuoCeiver technology provides 2 separate dedicated data channels
for RX and replaces the need for two, stand alone receiver systems.

Figure 8 Simultaneous 2 channel receive on nRF2401A
There is one absolute requirement for using the second data channel. For the
nRF2401A to be able to receive at the second data channel the frequency channel
must be 8MHz higher than the frequency of data channel 1. The nRF2401A must be
programmed to receive at the frequency of data channel 1. No time multiplexing is
used in nRF2401A to fulfil this function. In direct mode the MCU must be able to
handle two simultaneously incoming data packets if it is not multiplexing between the
two data channels. In ShockBurst it is possible for the MCU to clock out one data
channel at a time while data on the other data channel waits for MCU availability,
without any lost data packets, and by doing so reduce the needed performance of the
MCU.
