FX465 - Extended Code CTCSS Encoder/Decoder

General Description

The FX465 is a 3-volt, half-duplex predictive Continuous Tone Controlled Squelch System (CTCSS) encoder/decoder microcircuit.

The FX465 has integral voice-band filtering for prefiltering of Tx audio and the rejection of the CTCSS tone in receive.

Key Features

  • Low-Voltage (3-Volt) Supply 47 Programmable Sub-Audio Tones + NOTONE Meets MPT1306 and TIA/EIA 603 High Voiceband/CTCSS Isolation Separate Sub-Audio and Rx/Tx Audio Paths and Filtering Publication D/465/3 November 2004.
