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 164192 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-OnRadio. 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.

SWRS120A – REVISED MARCH 2012 Page 19 of 23 CC1125 4 Block Diagram A system block diagram of CC1125 is shown Figure 4.1. Figure 4.1 : System Block Diagram 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-OnRadio 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 PRODUCTION DATA information is current as of publication date. Products conform to specifications per the terms of Texas Instruments standard warranty. Production processing does not necessarily include testing of all parameters. SWRS120A – REVISED MARCH 2012 Page 20 of 23 CC1125 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.

SWRS120A – REVISED MARCH 2012 Page 21 of 23 CC1125 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.
