What is HT12E and HT12D?
HT12E is used to encode the data for RF Transmitter and HT12D is used to decode the data received by RF receiver. They are capable of Encoding 12 bit of information which consists of 8 address bits and 4 data bits.
What is HT12E?
HT12E is a 212 series encoder IC (Integrated Circuit) for remote control applications. It is commonly used for radio frequency (RF) applications. HT12E simply converts 12 bit parallel data in to serial output which can be transmitted through a RF transmitter.
How does the HT12E work?
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. HT12E begins a 4-word transmission cycle upon receipt of a transmission enable. This cycle is repeated as long as TE is kept low.
How do you test for HT12D?
The testing of IC HT12D will be measured by giving the input data to the pin AD12 and AD13 on the IC HT12E. Then, the addressing bits in the HT12D will be reviewed by using an oscilloscope.
What is HT12D encoder?
HT12D IC is a CMOS series 12-bit RF decoder. Mostly remote control applications have this technology. It gets to interface with the third device and helps it to decode 12-bits data. To receive the data between encoder and decoder address bits should be matched. The encoder can with any CMOS technology.
What is digital encoder?
An encoder (or “simple encoder”) in digital electronics is a one-hot to binary converter. That is, if there are 2n input lines, and at most only one of them will ever be high, the binary code of this ‘hot’ line is produced on the n-bit output lines. A binary encoder is the dual of a binary decoder.
How does RF transmitter and receiver work?
The RF transmitter receives serial data and transmits it wirelessly through through its RF antenna. The transmission occurs at the rate of 1 Kbps – 10 Kbps. RF receiver receives the transmitted data and it is operating at the same frequency as that of the transmitter.
