Functional Descriptions
Overview
The CMT2210/17A are ultra low power, high performance, low-cost OOK stand-alone RF receivers covering 300-960 MHz. They feature a low-IF architecture, requiring minimal external components. A fractional-N PLL synthesizer provides frequency generation with 24.8 Hz resolution. Analog blocks are calibrated on Power-On Reset (POR) for stable operation across temperature and voltage variations. Baseband filtering and demodulation are handled digitally. The 3-wire SPI interface allows configuration via the RFPDK and USB Programmer, simplifying design. The devices operate from 1.8-3.6 V, with typical receive currents of 3.8 mA (433.92 MHz) and 5.2 mA (868.35 MHz).
Modulation, Frequency and Symbol Rate
The CMT2210/17A supports OOK demodulation with symbol rates from 0.1 to 40 ksps. The CMT2210A covers 300-480 MHz (including 315 MHz and 433.92 MHz ISM bands), while the CMT2217A covers 300-960 MHz (including 315 MHz, 433.92 MHz, 868.35 MHz, and 915 MHz ISM bands). The frequency synthesizer offers a resolution of 24.8 Hz.

Embedded EEPROM and RFPDK
The RFPDK (RF Products Development Kit) is a PC application for configuring CMOSTEK NextGenRF™ products. It connects via a USB Programmer. Users can set parameters, program the device's EEPROM, save configurations to a list, or export them as hexadecimal files for mass production. This eliminates the need for external MCU control during application programming.

Internal Blocks Description
RF Front-end and AGC
The RF front-end includes a Low Noise Amplifier (LNA), I/Q mixer, and a wide-band power detector. It requires minimal external components (inductor, capacitor) for antenna matching. The Automatic Gain Control (AGC) loop ensures optimal linearity, selectivity, and sensitivity performance by regulating the RF front-end gain, even under strong out-of-band interference.
IF Filter
A fully integrated 3rd-order band-pass image rejection IF filter processes signals from the RF front-end, providing over 35 dB image rejection. The IF center frequency is dynamically adjusted to maintain optimal receiver sensitivity and out-of-band interference attenuation, compensating for manufacturing tolerances. IF bandwidth is automatically calculated based on RF frequency, crystal tolerance, and symbol rate.
RSSI
Multistage I/Q Log amplifiers process the IF filter output. Receive Signal Strength Indicator (RSSI) generators in these amplifiers produce DC voltages proportional to the input signal level, offering a 66 dB dynamic range. The device features a patented DC-offset cancellation engine to improve receiver sensitivity.
SAR ADC
An on-chip 8-bit SAR ADC digitizes the RSSI for OOK demodulation.
Crystal Oscillator
A 26 MHz crystal oscillator provides the reference clock for the PLL synthesizer and system clock for digital blocks. Appropriate loading capacitors (C2, C3) are required, chosen based on the crystal's specified load capacitance (CL).
Frequency Synthesizer
A fractional-N frequency synthesizer generates the LO frequency for the I/Q mixer. It is integrated except for the VCO tank inductor. Using a 26 MHz reference clock, it can generate frequencies from 300 to 480 MHz with 24.8 Hz resolution. The VCO operates at 2x the LO frequency. A high-Q tank inductor is recommended for optimal performance.
| LO Frequency Band | VCO Inductor (QFN16) | VCO Inductor (SOP16) |
|---|---|---|
| 315 MHz | 36 nH ±10% | 27 nH ±10% |
| 433.92 MHz | 18 nH ±10% | 15 nH ±10% |
| 868.35 MHz | 3.9 nH ±5% | - |
| 915 MHz | 3.6 nH ±5% | - |
LPOSC
An internal 1 kHz low power oscillator (LPOSC) drives the sleep timer for periodic wake-ups. The sleep time is configurable from 3 ms to over 37 hours. The LPOSC is automatically calibrated to maintain frequency tolerance within ±1%.
Operation Mode
The device supports two operation modes, selectable via the 'Duty-Cycle On-Off' option in the RFPDK:
- Always Receive Mode: The device powers up, tunes to frequency, and continuously receives RF signals. It consumes approximately 3.8 mA (433.92 MHz) in RX state.
- Duty-Cycle Receive Mode: The device cycles through SLEEP, XTAL, TUNE, and RX states. This mode saves power and allows for regular synthesizer re-tuning to maintain performance. The PUP sequence is longer (9.5 ms) due to LPOSC calibration.
Timing diagrams illustrate the state transitions and current consumption for both modes.
Advantages of Duty-Cycle Receive Mode:
- Maintains highest performance via regular frequency re-tune.
- Increases system stability through regular sleep cycles.
- Saves power for both transmitter and receiver devices.
Easy Duty-Cycle Configurations
For systems prioritizing stability and performance over minimal power consumption, an 'Easy Configuration' example is provided. In this example, a Tx device transmits data at 1.2 ksps (50 ms packet length). The receiver is configured with a minimum Sleep Time (3 ms), a long Rx Time (1 second), and the Tx sends 3 continuous packets. This ensures at least one packet is reliably received, with the DOUT pin indicating data availability. For power-sensitive applications, 'Precise Configuration' and 'Wake-On Radio' techniques are recommended.
nRSTO
The nRSTO pin outputs an active-low reset signal generated by the internal Power-On Reset (POR) circuit. This signal can be used to reset an external MCU. Timing characteristics for TPOR (POR delay) are provided based on TRISE (VDD rise time).
| TRISE (µs) | TPOR (µs) |
|---|---|
| 3,000 | 500 |
| 1,000 | 300 |
| 300 | 160 |
| 100 | 100 |
| 30 | 70 |
| 10 | 60 |
CLKO
The CLKO pin outputs a divided clock from the crystal oscillator when 'System Clock Output' is enabled in the RFPDK. This clock can drive an external MCU and is available during XTAL, TUNE, and RX states. The clock frequency is selectable.
