DECODIFICADOR RF HT12D circuito decodificador para modulos de radiofrecuencia

T12E is an encoder integrated circuit of 212 series of encoders. They are paired with 212 series of decoders for use in remote control system applications. It is mainly used in interfacing RF and infrared circuits. The chosen pair of encoder/decoder should have same number of addresses and data format. Simply put, HT12E converts the parallel inputs into serial output. It encodes the 12 bit parallel data into serial for transmission through an RF transmitter. These 12 bits are divided into 8 address bits and 4 data bits. HT12E has a transmission enable pin which is active low. When a trigger signal is received on TE pin, the programmed addresses/data are transmitted together with the header bits via an RF or an infrared transmission medium. HT12E begins a 4-word transmission cycle upon receipt of a transmission enable. This cycle is repeated as long as TE is kept low. As soon as TE returns to high, the encoder output completes its final cycle and then stops.

The HT8950 is a single chip CMOS LSI voice modulator. It provides 7 steps to shift the frequency of an input voice, producing a dramatical change in the output.

The HT9032 calling line identification receiver is a low power CMOS integrated circuit designed for receiving physical layer signals transmitted according to Bellcore TR-NWT-000030 and ITU-T V.23 specifications. The primary application of this device is for products used to receive and display the calling number, or message waiting indicator sent to subscribers from the central office facilities. The device also provides a carrier detection circuit and a ring detection circuit for easier system applications.

CIRCUITO INTEGRADO RECEPTOR MULTIFRECUENCIA DE DOBLE TONO.Is the series of Dual Tone Multi Frequency (DTMF) receivers. They employ digital counting techniques to detect and decode the 16 DTMF tones into 4 bit output code. HT9170 series receivers do not require any external filters as they use highly accurate switched capacitor filters for filtering low and high frequency signals from the DTMF tones. They also support power down (PWDN) and inhibit (INH) modes. PWDN mode is used to power off the crystal, while INH mode to inhibit the A, B, C & D DTMF tones. The clock is provided by a 3.58 MHz crystal. In simple terms, HT9170 IC detects and decodes the 16 DTMF tones into 4 bit output. In case the tones are not detected, the four output bits remain low. The DV pin goes high on detection of a valid tone.
