Descriptions
The CMT2113AW is ultra low-cost, highly flexible, high
performance, single-chip (G)FSK/OOK transmitters for
various 240 to 480 MHz wireless applications. It is part of
the CMOSTEK NextGenRFTM family, which includes a
complete line of transmitters, receivers and transceivers.
With very low current consumption, the device modulates
and transmits the data which is sent from the host MCU. An
embedded EEPROM allows the frequency, output power
and other features to be programmed into the chip using the
CMOSTEK USB Programmer and RFPDK. Alternatively, in
stock product of 433.92 MHz is available for immediate
demands without the need of EEPROM programming. The
CMT2113AW uses a 1-pin crystal oscillator circuit with the
required crystal load capacitance integrated on-chip to
minimize the number of external components. The device
can deliver up to +13 dBm output power. It operates from a
supply voltage of 1.8 V to 3.6 V, consumes 23.5 mA (FSK)
when transmitting at +10 dBm output power; and leaks only
20 nA when it is in sleep state, providing superior operation
life for battery powered applications. The CMT2113AW
transmitter together with the CMT2213AW receiver enables
an ultra low cost FSK RF link.

Note:
[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.
Caution! ESD sensitive device. Precaution should be used when handling the device in order
to prevent permanent damage.

Notes:
1. Connector J1 is a must for the CMT2113AW EEPROM access during development or manufacture.
2. The general layout guidelines are listed below. For more design details, please refer to “AN101 CMT211xA Schematic and
PCB Layout Design Guideline”.
Use as much continuous ground plane metallization as possible.
Use as many grounding vias (especially near to the GND pins) as possible to minimize series parasitic inductance
between the ground pour and the GND pins.
Avoid using long and/or thin transmission lines to connect the components.
Avoid placing the nearby inductors in the same orientation to reduce the coupling between them.
Place C0 as close to the CMT2113AW as possible for better filtering.
3. The table below shows the BOM of 315/433.92 MHz FCC/ETSI Compliant Application. For the BOM of other applications,
please refer to “AN101 CMT211xA Schematic and PCB Layout Design Guideline”.
