The MX165C MX165C 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 MX165C MX165C 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 (MX165CTN MX165CTN), 24-pin SOIC (MX165CDW MX165CDW), 24-pin PLCC (MX165CLH MX165CLH), and 24-pin PDIP (MX165CP MX165CP), the MX165C MX165C requires a single 3.3V to 5.0V supply and a 1MHz clock or crystal. © 1997 MX·COM Inc. www.mxcom.com Tele: 800 638-5577 910 744-5050 Fax: 910 744-5054 Doc. # 20480102.008 4800 Bethania Station Road, Winston-Salem, NC 27105-1201 USA All trademarks and service marks are held by their respective companies.

This pin should be bypassed to VSS by a capacitor mounted close to the device pins. 2 XTAL/CLOCK input 3 XTAL 4 LOAD/LATCH input Controls 8 on-chip latches. It is used to latch RX / TX , PTL, and D0D5. A logic 1 applied to this input places the 8 latches in the `transparent' mode. A logic 0 applied to this input places the 8 latches in the `latched' mode. In Parallel Mode, data is loaded and latched by a logic 1-0 transition (see Figure 4). In Serial Mode, data is loaded and latched by a 0-1-0 strobe pulse on this pin (see Figure 5). Internally pulled to VDD 5 D5 / SERIAL ENABLE 1 input Data input D5 (Parallel Mode).

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 VDD, peak to peak. Tuning fork crystals generally cannot meet this requirement. To obtain crystal oscillator design assistance, consult your crystal manufacturer. 2. The 0.1µF 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. © 1997 MX·COM Inc. www.mxcom.com Tele: 800 638-5577 910 744-5050 Fax: 910 744-5054 Doc. # 20480102.008 4800 Bethania Station Road, Winston-Salem, NC 27105-1201 USA All trademarks and service marks are held by their respective companies. Low Voltage CTCSS Encoder/Decoder 7 MX165C MX165C General Description 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 TIA/EIA-603. There are an additional eight CTCSS tones not specified in TIA/EIA-603 TIA/EIA-603 that the MX165C MX165C 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 MX165C MX165C 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).

CML Microcircuits COMMUNICATION SEMICONDUCTORS CML Product Data In the process of creating a more global image, the three standard product semiconductor companies of CML Microsystems Plc (Consumer Microcircuits Limited (UK), MX-COM, Inc (USA) and CML Microcircuits (Singapore) Pte Ltd) have undergone name changes and, whilst maintaining their separate new names (CML Microcircuits (UK) Ltd, CML Microcircuits (USA) Inc and CML Microcircuits (Singapore) Pte Ltd), now operate under the single title CML Microcircuits. These companies are all 100% owned operating companies of the CML Microsystems Plc Group and these changes are purely changes of name and do not change any underlying legal entities and hence will have no effect on any agreements or contacts currently in force. CML Microcircuits Product Prefix Codes Until the latter part of 1996, the differentiator between products manufactured and sold from MXCOM, Inc. and Consumer Microcircuits Limited were denoted by the prefixes MX and FX respectively. These products use the same silicon etc. and today still carry the same prefixes. In the latter part of 1996, both companies adopted the common prefix: CMX. This notification is relevant product information to which it is attached. CML Microcircuits (USA) [formerly MX-COM, Inc.] Product Textual Marking On CML Microcircuits (USA) products, the `MX-COM' textual logo is being replaced by a `CML' textual logo.
