CMT2150AW CMT2150AW 240 – 480 MHz OOK Stand-Alone Transmitter with Encoder Features  Embedded EEPROM  Very Easy Development with RFPDK  All Features Programmable  Frequency Range: 240 to 480 MHz  Symbol Rate: 0.5 to 40 ksps  Output Power: -10 to +13 dBm  Current Consumption: 8.5 mA @ +10 dBm  Sleep Current: < 20 nA  Stand-Alone, No External MCU Control Required  Embedded 1920, 1527 and 2262 Data Encoder  Up to 7 Configurable Data Pins for Push Buttons  LED Indicator for Low Battery Detection and Transmission  Sync ID Auto-Study with CMOSTEK Receiver  FCC / ETSI Compliant  RoHS Compliant  14-pin SOP Package Descriptions The CMT2150AW is a true single-chip, highly flexible, high performance, OOK RF transmitter with embedded data encoder ideal for 240 to 480 MHz wireless applications. The device integrates a data encoder that is not only compatible with the most common used encoding format of 1527 and 2262, but also a more efficient, flexible and powerful format of 1920 designed by CMOSTEK. Up to 7 configurable push buttons are supported in multiple button modes. When pairing the device to CMOSTEK receiver, the synchronization ID can be programmed into both of the transmitter and receiver during the manufacturing phase, or studied by the receiver from the transmitter remotely by end customers. An embedded EEPROM allows the RF and encoder parameters to be programmed into the chip using the CMOSTEK USB Programmer and the RFPDK. Alternatively, in stock product of 433.92 MHz is available for immediate demands without the need of EEPROM programming. The CMT2150AW is part of the CMOSTEK NextGenRFTM family, together with CMT225x series receivers, they enable ultra low cost, low power consumption RF links.

FCC/ETSI Compliant Application Schematic Notes: 1. Connector J1 is a must for the CMT2150AW EEPROM access during development or manufacture phase. 2. The general layout guidelines are listed below. For more design details, please refer to “AN111 CMT215x 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 CMT2150AW as possible for better filtering. 3.
