Remote control transmitter circuit.
Receiver decoding circuit.
The circuit is composedof F36-F/F36-J multi-channel radio remote control circuit. In the transmitter circuit, it usesDTMF encoding and decoding circuit to turn launch four-key input signal into a binary code inputand sent out by F36-F . In the receiver circuit, F36-J will receive the remote signal and pass demodulation decoding and reduce to four binary code. Four binary code passes a four - sixteen line decoder and turn to a four - sixteen line decoder. It controls a corresponding circuit.

ICRF002 uses ceramic resonators to replacethe different resonator. The receiving frequency can cover 300-440MHz. MICRF002 has two operating modes: scan mode and fixed mode. Scan mode accepts bandwidth of several hundreds of KHz. This mode is mainly used to support the use of LC oscillator transmitter. Because LC transmitting frequencyis higher. In the scan mode, the data communication rate is 2.5K Bytes per second. Bandwidth of fixed pattern is only a few dozens of KHz, and it uses this mode for the supporting of transmitter crystal frequency. Stabilization data rates is up to 10KBytes per second. In addition, the use of wake-up function can wake up decoder or CPU. It can minimize the power consumption. MICRF002 is a complete single-chip superheterodyne receiver circuit.
