以pt2260为编码芯片的遥控发射器电路原理

 

pt2260 is a remote control encoder paired with either pt2270 or pt2272 utilizing cmos technology.
it encodes data and address pins into a serial coded waveform suitable for rf modulation. pt2260 has
a maximum of 10 bits tri-state address pins providing up to 59,049 (or 310) address codes; thereby,
drastically reducing any code collision and unauthorized code scanning possibilities.
pt2260 is one of the first generation of encoder/decoder ics that utilizes the unique ptc technology.
when paired with pt2270, this encoder/decoder (pt2260/pt2270) pair can operate at very wide
temperature range (see features). thus, this very important feature enables your encoder/decoder to
operate under the worst environmental condition.
