Descriptions
The CMT2213AW is an ultra low power, high performance,
low-cost (G)FSK/OOK stand-alone RF receiver for various
300 to 480 MHz wireless applications. It is part of the
CMOSTEK NextGenRFTM family, which includes a
complete line of transmitters, receivers and transceivers. An
embedded EEPROM allows the frequency, symbol rate and
other features to be programmed into the device using the
CMOSTEK USB Programmer and RFPDK. Alternatively, in
stock products of 433.92 MHz is available for immediate
demands with no need of EEPROM programming. The
CMT2213AW operates from a supply voltage of 1.8 V to 3.6
V, when it is always on, it consumes only 4.3 mA current
while achieving -111 dBm receiving sensitivity. It consumes
even less power when working in duty-cycle operation
mode via the built-in sleep timer. The device provides
demodulated data, power-on reset output as well as a
system clock output for use by an external microcontroller
or decoder. The CMT2213AW receiver together with the
CMT2113AW transmitter enables an ultra low cost RF link.

Notes:
[1]. Stresses above those listed as “absolute maximum ratings” may cause permanent damage to the device. This is a stress
rating only and functional operation of the device under these conditions is not implied. Exposure to maximum rating
conditions for extended periods may affect device reliability.
[2]. The CMT2213AW is high-performance RF integrated circuits with VCON/P pins having an ESD rating < 2 kV HBM.
Handling and assembly of this device should only be done at ESD-protected workstations.
Caution! ESD sensitive device. Precaution should be used when handling the device in order
to prevent permanent damage.

5.1 Overview
The CMT2213AW is an ultra low power, high performance, low-cost (G)FSK/OOK stand-alone RF receiver for various 300 to 480
MHz wireless applications. It is part of the CMOSTEK NextGenRFTM family, which includes a complete line of transmitters,
receivers and transceivers. The chip is based on a fully integrated, low-IF receiver architecture. The low-IF architecture facilitates
a very low external component count and does not suffer from powerline - induced interference problems. The synthesizer
contains a VCO and a low noise fractional-N PLL with an output frequency resolution of 24.8 Hz. The VCO operates at 2x the
Local Oscillator (LO) frequency to reduce spurious emissions. Every analog block is calibrated on each Power-on Reset (POR) to
the internal reference voltage. The calibration helps the device to finely work under different temperatures and supply voltages.
The baseband filtering and demodulation is done by the digital demodulator. The demodulated signal is output to the external
MCU via the DOUT pin. No external MCU control is needed in the applications.
The 3-wire SPI interface is only used for configuring the device. The configuration can be done with the RFPDK and the USB
Programmer. The RF Frequency, symbol rate and other product features are all configurable. This saves the cost and simplifies
the design, development and manufacture. Alternatively, in stock products of 433.92 MHz is available for immediate demands
with no need of EEPROM programming. The CMT2213AW operates from 1.8 to 3.6 V so that it can finely work with most
batteries to their useful power limits. The receive current is only 4.3 mA while achieving -111 dBm receiving sensitivity (FSK @
433.92 MHz FRF, 9.6 ksps SR). The CMT2213AW receiver together with the CMT2113AW transmitter enables an ultra low cost
RF link.
5.2 Modulation, Frequency Deviation and Symbol Rate
The CMT2213AW supports FSK/GFSK demodulation with the symbol rate from 0.1 to 100 ksps, as well as the OOK
demodulation with the symbol rate from 0.1 to 40 ksps. The supported deviation of the (G)FSK modulation ranges from 1 to 200
kHz. The device continuously covers the frequency range from 300 to 480 MHz, including the license free ISM frequency band
around 315 MHz and 433.92 MHz. The internal frequency synthesizer contains a high-purity VCO and a low noise fractional-N
