CMT2110A/2210A One-Way RF Link Development Kits User's Guide
Introduction
CMT2110A/2210A One-Way RF Link Development Kits (Development Kits) are a set of the hardware and
software tools designed to help the users to easily evaluate the performance and demonstrate the features of
products CMT2110A and CMT2210A. These two devices are part of the CMOSTEK Microelectronics Co., Ltd.
TM
(CMOSTEK) NextGenRF
family, which include a complete line of transmitters, receivers and transceivers. The
CMT2110A is an ultra low-cost, highly flexible, high performance, single-chip OOK transmitter for various 240 to
480 MHz wireless applications. The CMT2210A is an ultra low-cost, highly flexible, high performance, single-chip
OOK receiver for various 300 to 480 MHz wireless applications. These two devices are optimized for the low
system cost, low power consumption, battery-powered one-way RF link application with their highly integrated
and low power design.
The Development Kits contain the components of two evaluation boards named RF-EB, a Tx evaluation module
named CMT2110A-EM, an Rx evaluation module named CMT2210A-EM, a USB Programmer and a PC
application named RFPDK (RF Products Development Kit). The package of the Development Kits is shown in
Figure 1.

  • Page 5 CMT2110A, CMT2201A and other RF products. CMT2110A-EM The CMT2110A-EM is the Tx evaluation module. The user can use it to evaluate the CMT2110A performance and features. CMT2210A-EM The CMT2210A-EM is the Rx evaluation module.
  • Page 6: Application Schemes

    This scheme allows the user to freely customize all product features and program them into the chips. Once the programming is done successfully, the evaluation module is ready to be integrated into the user’s own application systems. Moreover, the users can program chip configurations to their self-designed CMT2110A/2210A modules as long as the programming interface is reserved.
  • Page 7 Install the RFPDK to the computer. Refer to Section 7.1 for the detail procedure for the installation. Start Configuring CMT2110A/2210A on the RFPDK and the USB Programmer. Once the configuration is done, the user can use the evaluation modules in the actual RF system.

    AN103 3. CMT2110A-EM The CMT2110A-EM is a Tx evaluation module with CMT2110A, the necessary external components and the matching network. The EM-Connector on the back side of the module allows the connection to the RF-EB or USB Programmer. The definitions of the EM-Connector pins are listed in Table 1.
  • Page 9: Cmt2210A-Em

    The evaluation module contained in this Development Kits is designed with the matching network at 433.92 MHz. For application with different frequencies, the matching network might need to be changed. See “Chapter 10 Appendix: CMT2110A-EM and CMT2210A-EM Schematics” for the CMT2210A-EM Schematic.
