The MX465 CTCSS Encoder/Decoder is a low voltage, CMOS device that meets TIA/EIA-603 Standards. The MX465 will encode and decode the tones 159.8Hz, 183.5Hz, 189.9Hz, 196.6Hz, 199.5Hz, 206.5Hz,

229.1Hz, and 254.1Hz in addition to the 39 standard CTCSS tones, for a total of 47 CTCSS tones + Notone. With the incorporation of the on-chip TX and RX speech filter, the MX465 enhances voice/tone multiplexing by attenuating TX and RX speech 36dB at frequencies below 250Hz while passing signals > 300Hz with only 1dB of ripple. This not only minimizes CTCSS talk-off in the TX mode but also improves Hum and Noise performance in the RX mode.

Available in the following package styles: 24-pin TSSOP (MX465TN), 24-pin SSOP (MX465DS), 24-pin SOIC (MX465DW), 24-pin PLCC (MX465LH), 24-pin PDIP (MX465P), and 24-pin CDIP (MX465J) the MX465 requires a single 3.3V to 5.0V supply and a 4MHz clock or crystal.

Table 2: External Components

External Components Notes:

1. The values specified for R1, C2, and C3 have been found to be satisfactory when used with a crystal (X1) whose equivalent series resistance is  1000. For best results, a crystal oscillator design should drive the clock inverter input with signal levels of at least 40% of V

, peak to peak. Tuning fork

DD

crystals generally cannot meet this requirement. To obtain crystal oscillator design assistance, consult your crystal manufacturer.

2. The 0.1F value for the DC Blocking capacitors, C4, C5, C7, C8, C9, C10, and C11 is not a requirement. For the capacitors C4, C5, and C10, the input impedance is internal to the device and specified typical as 550k. For the remaining capacitors external circuits will be important in determining the input impedance.

Low Voltage CTCSS Encoder/Decoder 7 MX465

4 General Description

4.1 Description

Voice on shared radio channels are multiplexed with a subaudible CTCSS (Continuous Tone Controlled Subaudible Squelch) tone as a means of directing messages among user groups sharing the same RF frequencies. CTCSS modulates the transmitter with a discrete tone, from 39 standard CTCSS tones in the range (67.0Hz to 250.0Hz) according to TIA/EIA-603. There are an additional eight CTCSS tones not specified in TIA/EIA-603 that the MX465 will encode and decode. They are : 159.8Hz, 183.5Hz, 189.9Hz,

196.6Hz, 199.5Hz, 206.5Hz, 229.1Hz, and 254.1Hz, for a total of 47 CTCSS tones plus Notone. The MX465 also incorporates TX/RX on chip speech filters. In early CTCSS designs, TX speech was not

filtered from the CTCSS tone, rather the filtering was dependent upon the host transmitter’s pre-emphasis network. At only 6dB/octave, the attenuation of speech components at higher CTCSS tones was only a few dB which resulted in talk-off (low frequency voice components unsquelching the receiver audio).
