Precision Tone Decoder

General Description

Detects the presence of a single tone at a specified centre frequency. Features 16-bit data samples, programmable tone frequency, adjustable detection bandwidth and a high performance Digital Down Converter. Ideal for precision tone detection or as a building block in FSK/OOK/ASK demodulators.

Key Design Features

- 16-bit signed input and output data samples
- Samples may be either complex or real
- Includes our precision 16-bit DDS component
- Narrow or wide detection bandwidths
- Bandwidths to within 0.005 x sample freq.
- Programmable tone centre frequency
- Doubles as a precision Digital Down Converter
- Choice of low pass filter responses
- Suitable for FPGA sample rates of 150MHz+

Precision Tone Decoder

Applications

- Touch tone decoding (e.g DTMF tones)
