Details
The AK2345 is an IC which supports CTCSS (Continuous Tone Controlled Squelch System), compatible with the TIA/EIA-603 standard.A single CTCSS may be selected from among 50 different frequencies within a range of from 67 to 254.1 Hz. By sending that CTCSS simultaneously with the voice signal during transmission, and by setting the audio circuit so that it operates only when a CTCSS of that frequency is detected, it is possible to have multiple communications on the same radio frequency.TX has a built-in Adder CTCSS and voice signal, and RX has a built-in high-speed CTCSS Decoder respectively.Voice signal filters, a limiter, op-amp, and other circuits are integrated, making it possible to configure a radio base band unit, especially FRS from a single chip. Features1. CTCSS (Continuous Tone Controlled Squelch System) Encoder/Decoder.2. Programmable for up to 50 CTCSS frequencies.3. Integrated CTCSS signal elimination filter.4. Built-in Adder TX CTCSS/CDCSS and voice signal.5. Built-in high speed CTCSS Decoder.6. Conform to CDCSS. (Continuous Digital Controlled Squelch System)7. Integrated voice signal circuits such as a limiter, splatter filter, etc.8. Built-in (3.6864 MHz or 4.194304 MHz) oscillator circuit with crystal oscillator. (Page 25)9. Control register controlled via serial interface.10. CMOS Process low voltage operation. (1.8V…5.5V)11. Compact plastic package is used. (24 pin VSOP)
