CYBLE-413136-01
Figure 9. Reset Timing
Integrated Radio Transceiver
The CYBLE-413136-01 has an integrated radio transceiver that is optimized for 2.4 GHz Bluetooth wireless systems. It has been
designed to provide low power, low cost, and robust communications for applications operating in the globally available 2.4 GHz unli-
censed ISM band. It is fully compliant with Bluetooth Radio Specification 3.0 and meets or exceeds the requirements to provide the
highest communication link quality of service.
Transmitter Path
The CYBLE-413136-01 features a fully integrated transmitter. The baseband transmit data is GFSK modulated in the 2.4 GHz ISM
band.
Digital Modulator
The digital modulator performs the data modulation and filtering required for the GFSK signal. The fully digital modulator minimizes
any frequency drift or anomalies in the modulation characteristics of the transmitted signal.
Power Amplifier
The CYBLE-413136-01 has an integrated power amplifier (PA) on the silicon device as well as a high power external power amplifier
(PA) integrated on the module. The total output power that this module is designed to achieve is +8 dBm.
Receiver Path
The receiver path uses a low IF scheme to down convert the received signal for demodulation in the digital demodulator and bit syn-
chronizer. The receiver path provides a high degree of linearity, and an extended dynamic range to ensure reliable operation in the
noisy 2.4 GHz ISM band. The front-end topology, which has built-in out-of-band attenuation, enables the CYBLE-413136-01 to be
used in most applications without off-chip filtering.
Digital Demodulator and Bit Synchronizer
The digital demodulator and bit synchronizer take the low-IF received signal and perform an optimal frequency tracking and bit syn-
chronization algorithm.
Receiver Signal Strength Indicator
The radio portion of the CYBLE-413136-01 provides a receiver signal strength indicator (RSSI) to the baseband. This enables the
controller to take part in a Bluetooth power-controlled link by providing a metric of its own receiver signal strength to determine
whether the transmitter should increase or decrease its output power.
