Product details
Overview
CC1020-RTR1 from Texas Instruments is a true single-chip UHF RF transceiver for narrowband systems, operating in 402–470 MHz and 804–930 MHz bands with programmable output power up to +10 dBm (433 MHz), –118 dBm sensitivity at 12.5 kHz channel spacing, and support for OOK/FSK/GFSK modulation at data rates up to 153.6 kBaud. It integrates low-IF receiver, digital RSSI, carrier sense, and AFC for crystal temperature drift compensation - deployed in EN 300 220–compliant AMR and wireless security systems.
For engineers reviewing the CC1020-RTR1 datasheet, CC1020-RTR1 pinout, CC1020-RTR1 application, or CC1020-RTR1 equivalent, this page delivers verified functional block architecture, QFN-32 package terminal mapping, real-world RF performance metrics (adjacent channel rejection ≥32 dB, image rejection up to 62 dB with calibration), and validated alternatives for narrowband SRD designs targeting ARIB STD-T67 or FCC Part 15 compliance.
Technical Context
The CC1020-RTR1 implements a low-IF receiver architecture with 307.2 kHz intermediate frequency, digitally programmable channel filter bandwidth (9.6–307.2 kHz), and integrated bit synchronizer supporting NRZ and Manchester coding. Its PLL-based frequency synthesizer enables <300 Hz step resolution in 402–470 MHz band and <600 Hz in 804–930 MHz band, with AFC capability compensating crystal aging and thermal drift without requiring TCXO.
Transmit path features on-chip PA with programmable output power, while receive path includes dual-LNA stages, I/Q demodulator with gain/phase calibration support, and ADC-based RSSI with ±3 dB accuracy over 55 dB dynamic range. All configuration occurs via 4-wire SPI interface (PSEL/PCLK/PDI/PDO), with DIO/DCLK handling synchronous/asynchronous data I/O and LOCK indicating PLL lock status.

Pinout & Package
VQFNP (32-pin QFN), 7.00 mm × 7.00 mm body size, Pb-free, exposed die-attach pad soldered to solid ground plane per TI mechanical guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar narrowband RF transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CC1120RHBR | Successor device with higher sensitivity (–120 dBm), wider frequency range (27–1050 MHz), and integrated MCU interface enhancements; requires different layout and firmware adaptation. | Targets next-gen designs needing extended range or multi-band flexibility; not drop-in compatible due to pinout and register map changes. | Select CC1120RHBR for new designs requiring improved SNR or broader regulatory coverage; retain CC1020-RTR1 for legacy AMR/telemetry where qualification stability is critical. |
| SI4432-B1B-FMR | Sub-GHz transceiver with comparable 433/868 MHz support, –121 dBm sensitivity, but uses different SPI framing and lacks integrated AFC calibration logic. | Better suited for high-volume consumer remotes; requires external loop filter tuning and separate RSSI processing in host MCU. | Choose SI4432-B1B-FMR when cost-per-unit is prioritized and design team has RF calibration expertise; CC1020-RTR1 offers faster time-to-market for EN 300 220–certified systems. |
Compared with CC1120RHBR and SI4432-B1B-FMR, the CC1020-RTR1 delivers proven regulatory compliance for narrowband SRD applications with minimal external components, while its mature ecosystem and documented reference designs reduce certification risk - especially where long-term supply continuity and field-proven reliability outweigh raw performance gains.

FAQ
What is the maximum data rate supported by the CC1020-RTR1?
The CC1020-RTR1 supports a maximum data rate of 153.6 kBaud in NRZ mode, equivalent to 153.6 kbps. In Manchester encoding, the effective throughput is halved to 76.8 kbps due to bit doubling. This rate is achievable with 500 kHz channel spacing and ±72 kHz frequency deviation, as specified in the RF Receive section of the datasheet. The CC1020-RTR1 maintains full functionality-including sensitivity and adjacent channel rejection-at this rate.
Does the CC1020-RTR1 require an external TCXO for EN 300 220 compliance?
No, the CC1020-RTR1 does not require an external TCXO for EN 300 220 compliance. Its integrated AFC (Automatic Frequency Control) and fine-step PLL programmability enable crystal temperature drift compensation using standard ±5.7 ppm crystals at 433 MHz. The CC1020-RTR1 achieves required frequency stability through software-controlled calibration, eliminating TCXO cost and board space.
How many power supply domains does the CC1020-RTR1 use, and what are their voltage requirements?
The CC1020-RTR1 uses separate analog (AVDD) and digital (DVDD) supply domains, both rated for 2.3 V to 3.6 V operation. TI recommends a common 3.0 ±0.1 V supply for both domains to meet ARIB STD-T67 output power tolerance and selectivity requirements. The device includes multiple AVDD pins (12, 13, 16, 18, 20, 22, 23, 27, 29) and two DVDD pins (5, 31), each requiring local decoupling per Section 5.11.
What is the role of the LNA_EN and PA_EN pins on the CC1020-RTR1?
The LNA_EN and PA_EN pins on the CC1020-RTR1 are general-purpose digital outputs that can be configured to enable external low-noise amplifiers or power amplifiers. They are not internally connected to the CC1020-RTR1's own LNA or PA stages. This allows system designers to extend sensitivity beyond –118 dBm or boost output power above +10 dBm while retaining full control over sequencing and biasing via the host MCU.
Can the CC1020-RTR1 operate in frequency-hopping spread spectrum (FHSS) mode?
Yes, the CC1020-RTR1 is explicitly suited for frequency-hopping systems, as stated in its official features list. Its fast PLL settling time and programmable frequency synthesis (with <300 Hz resolution in 402–470 MHz band) enable rapid channel switching. However, hop sequence control, timing, and synchronization must be implemented externally by the host microcontroller - the CC1020-RTR1 provides the RF layer agility but no built-in FHSS protocol engine.
