The HT68F2420 is an IR driver MCU with fully integrated high accuracy oscillators and an IR LED driver circuit. It is suitable for applications of IR remote controllers, IR transmission products and high precision clocks, etc.
It includes an internal integrated adjustable IR carrier frequency generator (4kHz to 1MHz), four common IR carrier frequency options of 36 / 38 /40 / 56kHz and the internal oscillation frequency which can be adjusted to 3.996 / 3.99 / 4.0 / 3.976MHz. This effectively reduces the frequency division error making the IR transmitter carrier frequency more compatible with the IR receiver carrier frequency, which will increase the IR transmission distance.
NOTE
Each purchasing unit includes 5 pieces of IC.
