Additional Details

The MC13155DR2 supports both Frequency Shift Keying (FSK) and On-Off Keying (OOK) modulation schemes, allowing it to be used in a variety of applications. The integrated PLL ensures stable frequency generation and modulation, improving the overall performance of the transmitter. The adjustable output power allows the transmitter to be optimized for different applications. The data rate is up to 20 kbps, which is sufficient for many low-power wireless applications. The wake-up timer can be used to further reduce power consumption by putting the transmitter into a sleep mode when it is not actively transmitting data. The device operates at low voltages, typically in the range of 2.1V to 3.6V, making it ideal for battery-powered applications. The MC13155DR2 is available in a small footprint package, further reducing the overall system size.
