General Description
The CYF115 is a high performance, easy to use, single chip ASK Transmitter IC for remote wireless applications in the 300 to 450MHz frequency band. This transmitter IC is a true "data-in, antenna-out" monolithic device. CYF115 has three strong attributes: power delivery, operating voltage and operating temperature. In terms of power, the CYF115 is capable of delivering +10 dBm into a 50Ω load. This power level enables a small form factor transmitter (lossy antenna) such as a key fob transmitter to operate near the maximum limit of transmission regulations. In terms of operating voltage, the CYF115 operates from 1.8V to 3.6V. Many transmitter ICs in the same frequency band stop operating below 2.0V. The CYF115 will work with most batteries to the end of their useful limits. In terms of operating temperature, the CYF115 operates from -40°C to +85°C
The CYF115 is easy to use. It requires a reference frequency (RF carrier frequency divided by 32 times) generated from a crystal with a few additional external parts to create a complete versatile transmitter.
The CYF115 operates with ASK/OOK (Amplitude Shift Keying/On-Off Keyed) UHF receiver types from wide-band super-regenerative radios to narrow-band, high performance super-heterodyne receivers. CYF115's maximum ASK data rate is 10kbps (Manchester Encoding)
The CYF115 transmitter solution is ideal for industrial and consumer applications where simplicity and form factor are important.
For enhanced power saving, CYF115 includes power managing function. The power managing function Enables transmitter activated as long as high transient data input trigger signals are received. The transmitter will also be automatically switched off if there are no data input transients for a time exceeding approximately 75ms.
