Description
The CC1125 is
a fully integrated single-chip radio
transceiver designed for high performance at very low
power and low voltage operation in cost effective wireless
systems. All filters are integrated, removing the need for
costly external SAW and IF filters. The device is mainly
intended for the ISM (Industrial, Scientific and Medical)
and SRD (Short Range Device) frequency bands at 164-
192 MHz, 274-320 MHz, 410-480 MHz and 820-960 MHz.

The CC1125 provides extensive hardware support for
packet handling, data buffering, burst transmissions, clear
channel assessment, link quality indication and Wake-On-
Radio. The CC1125 main operating parameters can be
controlled via an SPI interface. In a typical system, the
CC1125 will be used together with a microcontroller and
only few external passive components.

4.1
Frequency Synthesizer
At the heart of CC1125 there is a fully integrated, fractional-N, ultra high performance frequency
synthesizer. The frequency synthesizer is designed for excellent phase noise performance,
providing very high selectivity and blocking performance. The system is designed to comply with
the most stringent regulatory spectral masks at maximum transmit power.
Either a crystal can be connected to XOSC_Q1 and XOSC_Q2, or a TCXO can be connected to
the EXT_XOSC input. The oscillator generates the reference frequency for the synthesizer, as
well as clocks for the ADC and the digital part. To reduce system cost, CC1125 has high accuracy
frequency estimation and compensation registers to measure and compensate for crystal
inaccuracies, enabling the use of lower cost crystals. If a TCXO is used, the CC1125 will
automatically turn the TCXO on and off when needed to support low power modes and Wake-On-
Radio operation.
4.2
Receiver
CC1125 features a highly flexible receiver. The received RF signal is amplified by the low-noise
amplifier (LNA) and down-converted in quadrature (I and Q) to the intermediate frequency (IF). At
IF, the I/Q signals are digitized by the high dynamic range ADCs.
An advanced Automatic Gain Control (AGC) unit adjusts the front end gain, and enables the
CC1125 to receive both strong and weak signals, even in the presence of strong interferers. High
attenuation channel and data filtering enable reception with strong neighbor channel interferers.
The I/Q signal is converted to a phase / magnitude signal to support both FSK and OOK
modulation schemes.
A sophisticated pattern recognition algorithm locks onto the synchronization word without need for
preamble settling bytes. Receiver settling time is therefore reduced to the settling time of the

AGC, typically 4 bits. The advanced pattern recognition also greatly reduces the problem of false
sync triggering on noise, further reducing power consumption and improving sensitivity and
reliability. The pattern recognition logic can also be used as a high performance preamble
detector to reliably detect a valid preamble in the channel.
A novel I/Q compensation algorithm removes any problem of I/Q mismatch and hence avoids time
consuming and costly I/Q / image calibration steps in production or in the field.
4.3
Transmitter
The CC1125 transmitter is based on direct synthesis of the RF frequency (in-loop modulation). To
achieve effective spectrum usage, CC1125 has extensive data filtering and shaping in TX to support
high throughput data communication in narrowband channels. The modulator also controls power
ramping to remove issues such as spectral splattering when driving external high power RF
amplifiers.
4.4
Radio Control and User Interface
The CC1125 digital control system is built around MARC (Main Radio Control) implemented using
an internal high performance 16 bit ultra low power processor. MARC handles power modes,
radio sequencing and protocol timing.
A 4-wire SPI serial interface is used for configuration and data buffer access. The digital
baseband includes support for channel configuration, packet handling, and data buffering. The
host MCU can stay in power down until a valid RF packet has been received, and then burst read
the data, greatly reducing the power consumption and computing power required from the host
MCU.
The CC1125 radio control and user interface is based on the widely used CC1101 transceiver to
enable easy SW transition between the two platforms. The command strobes and the main radio
states are the same for the two platforms.
For legacy formats CC1125 also has support for two serial modes. In synchronous serial mode
CC1125 performs bit synchronization and provides the MCU with a bit clock with associated data. In
transparent mode CC1125 outputs the digital baseband signal using a digital interpolation filter to
eliminate jitter introduced by digital filtering and demodulation.
4.5
Enhanced Wake-On-Radio (eWOR)
eWOR, using a flexible integrated sleep timer, enables automatic receiver polling with no
intervention from the MCU. The CC1125 will enter RX, listen and return to sleep if a valid RF packet
is not received. The sleep interval and duty cycle can be configured to make a trade-off between
network latency and power consumption. Incoming messages are time-stamped to simplify timer
re-synchronization.
The eWOR timer runs off an ultra low power 32 kHz RC oscillator. To improve timing accuracy,
the RC oscillator can be automatically calibrated to the RF crystal in configurable intervals.
4.6
Sniff Mode
The CC1125 supports very quick start up times, and requires very few preamble bits. Sniff Mode
uses this to dramatically reduce the current consumption while the receiver is waiting for data.
Since the CC1125 is able to wake up and settle much faster than the length of most preambles, it is
not required to be in RX continuously while waiting for a packet to arrive. Instead, the enhanced
wake-on-radio feature can be used to put the device into sleep periodically. By setting an
appropriate sleep time, the CC1125 will be able to wake up and receive the packet when it arrives
with no performance loss. This removes the need for accurate timing synchronization between
transmitter and receiver, and allows the user to trade off current consumption between the
transmitter and receiver.

4.7
Antenna Diversity
Antenna diversity can increase performance in a multi-path environment. An external antenna
switch is required. The switch can be automatically controlled by CC1125 using one of the GPIO
pins (also support for differential output control signal typically used in RF switches).
If antenna diversity is enabled, the GPIO will alternate between states until a valid RF input signal
is detected. An optional acknowledge packet can be transmitted without changing GPIO state.
An incoming RF signal can be validated by received signal strength, by using the automatic
preamble detector, or a combination of the two. Using the preamble detector will make a more
robust system and avoid the need to set a defined signal strength threshold, as this threshold will
set the sensitivity limit of the system.
