and the second IF of 450kHz. Incoming signals from the
antenna are mixed with the local signal from the PLL circuit
to produce the fi rst IF of 49.95MHz. This is then mixed with
the 50.4MHz second local oscillator output to produce the
450kHz second IF. The transmit signal frequency is gener­ated by the PLL VCO, and modulated by the signal from the
DSP. It is then amplifi ed and fed to the antenna.

3-2. IF circuit

The fi rst IF signal is passed through a four-pole monolithic
crystal fi lter (XF1) to reject adjacent channel signals. The fi l­tered fi rst IF signal is amplifi ed by the fi rst IF amplifi er (Q303)
and then applied to the IF system IC (IC302). The IF system
IC provides a second mixer, AGC amplifi er, and RSSI (Re­ceived Signal Strength Indicator).

The second mixer mixes the first IF signal with the

50.4MHz of the second local oscillator output and produces
the second IF signal of 450kHz.

The second IF signal is passed through the ceramic fi lter
(CF1) to reject the adjacent channel signal. The fi ltered sec­ond IF signal is amplifi ed by the AGC amplifi er.

The signal from the AGC amplifier is input to the ASIC
(IC610) through the ceramic fi lter (CF2).

3-3. Audio amplifi er circuit

Audio processing (high-pass filter, low-pass filter, de­emphasized and so on) at FM mode and decoding at NXDN
mode are processed by the DSP. The audio signal from
IC610 and IC603 goes through the amplifier (IC904). The
signal then goes through an electronic volume control (IC4),
and AF amplifi er (IC901).

While AFSW is High, the power supply of audio power
amplifi er (IC901) is activated, and the output to the speaker
turns ON.

3-4. Squelch circuit

It amplifi es the demodulated noise signal from IC610 af­ter fi ltering through the LPF and HPF circuit. The amplifi ed
signal is then converted to a DC signal by the detection cir­cuit. The converted signal is fed back to IC610.

4-2. Baseband circuit

The audio signal output from the baseband circuit is con­verted to digital data with a sampling frequency of 48kHz.
This digital data is sent to the DSP (IC603), and voice signals
of 300Hz or lower and frequencies of 3kHz or higher are cut

off and the audio range of 300Hz to 3kHz is extracted. The
audio signal is then pre-emphasized in FM mode and syn­thesized with the signals, such as QT and DQT, as required,
and is then output from IC610. In Digital mode, the audio
signal is converted to the 4-Level FSK baseband signal and
output from IC610. The DTMF and MSK baseband signals
are also generated by the DSP and output by IC610

4-3. VOX

The DSP detects the audio level. If the detected level be-

comes higher than the threshold level, the VOX starts.

4-4. Drive and Final amplifi er

The signal from the T/R switch (D413 is on) is amplifi ed
by the pre-drive amplifier (Q102) to 16~17dBm. It makes
it possible to spoil input to the drive amplifier by control­ling the power supply of the pre-drive amplifier with the
PD switch (Q110). The output of the pre-drive amplifi er is
amplifi ed by the drive and fi nal amplifi ers (Q103, Q104) to

5.0W (1.0W when the power is low). Q103 and Q104 are
MOS FETs. The output of the fi nal amplifi er is then passed
through the harmonic fi lter (LPF) and antenna switch (D102,
D103 are on) and applied to the antenna terminal.

The APC circuit always monitors the current flowing
through the RF power amplifi er (Q104) and keeps a constant
current. The voltage drop at R153, R154 and R155 is caused
by the current fl owing through the RF power amplifi er and
this voltage is applied to the differential amplifier (IC101
1/2). IC101 (2/2) compares the output voltage of IC101 (1/2)
with the reference voltage from IC610, and the output of
IC101 (2/2) controls the VGG of Q103 and Q104 to make the
both current constant. The change of power high/low is car­ried out by the change of the reference voltage. Q106, Q107
and Q108 are turned on and Q105 and Q109 are turned off
during transmission and the APC circuit is active.

5. PLL Frequency Synthesizer

5-1. TCXO (X401)

The TCXO (X401) generates a reference frequency of

16.8MHz for the PLL frequency synthesizer. This reference
frequency is applied to pin 9 of the PLL IC (IC403) and is
connected to the IF circuit as a 2nd local signal through the
Tripler (Q301).

The frequency adjustment is achieved by switching the
ratio of dividing frequency. The resolution of the adjusting
frequency is approximately 4Hz.

5-2. VCO

There is a RX VCO and a TX VCO.

The TX VCO (Q402) generates a transmit carrier and the
RX VCO (Q401) generates a 1st local signal. For the VCO
oscillation frequency, the transmit carrier is 450 to 520MHz
(K,K2,K3) or 400 to 470MHz (K4,K5,K6,E,E2,E3) and the 1st
local receive signal is 400.05 to 470.05MHz (K,K2,K3) or

350.05 to 420.05MHz (K4,K5,K6,E,E2,E3).

The VCO oscillation frequency is determined by one sys­tem of operation switching terminal “T/R” and two systems
of voltage control terminals “CV” and “ASSIST”.

IC101

(1/2)

The operation switching terminal, “T/R”, is controlled by
the control line (/T_R) output from the ASIC (IC610). When
the /T_R logic is low, the VCO outputs the transmit carrier
and when it is high, it outputs a 1st local receive signal.

The voltage control terminals, “CV” and “ASSIST”, are
controlled by the PLL IC (IC403) and ASIC (IC610) and the
output frequency changes continuously according to the
applied voltage. For the modulation input terminal, “VCO_
MOD”, the output frequency changes according to the
applied voltage. This is used to modulate the VCO output.
“VCO_MOD” works only when “/T_R” is low.

IC101

(2/2)

5-3. PLL IC (IC403)

The PLL IC compares the differences in phases of the
VCO oscillation frequency and the TCXO reference frequen­cy, returns the difference to the VCO CV terminal and real­izes the “Phase Locked Loop” for the return control. This
allows the VCO oscillation frequency to accurately match
(lock) the desired frequency.

14

CIRCUIT DESCRIPTION

NX-320

When the frequency is controlled by the PLL, the fre­quency convergence time increases as the frequency differ­ence increases when the set frequency is changed. To sup­plement this, the ASIC is used before control by the PLL IC
to bring the VCO oscillation frequency close to the desired
frequency. As a result, the VCO CV voltage does not change
and is always stable at approximately 2.5V.

The desired frequency is set for the PLL IC by the ASIC
(IC610) through the 3-line “SDO1”, “PCK_RF”, “/PCS_RF”
serial bus. Whether the PLL IC is locked or not is monitored
by the ASIC through the “PLD” signal line. If the VCO is not
the desired frequency (unlocked), the “PLD” logic is low.

The modulation signal of the Low-speed data is applied to
pin 23 of the PLL IC (IC403).

The connection destination of the signal output from the
buffer amplifier (Q408) is changed with the diode switch
(D413) that is controlled by the transmission power supply,
50T, and the diode switch (D412) that is controlled by the
receive power supply, 50R. If the 50T logic is high, it is con­nected to a send-side pre-drive (Q102). If the 50T logic is
low, it is connected to a receive-side mixer (Q201).

6. Control Circuit

The control circuit consists of the ASIC (IC610) and its pe-

ripheral circuits. IC610 mainly performs the following:

1) Switching between transmission and reception by PTT
signal input.

2) Reading system, zone, frequency, and program data from
the memory circuit.

3) Sending frequency program data to the PLL.

4) Controlling squelch on/off by the DC voltage from the
squelch circuit.

5) Controlling the audio mute circuit by decode data input.

6-1. ASIC

The ASIC (IC610) is a 32-bit RISC processor, equipped

with peripheral function and ADC/DAC.

This ASIC operates at 18.432MHz clock and 3.3V/1.5V

DC. It controls the fl ash memory, SRAM, DSP, the receive
circuit, the transmitter circuit, the control circuit, and the dis­play circuit and transfers data to or from an external device.

6-2. Memory circuit

The memory circuit consists of the ASIC (IC610), the
SRAM (IC605), and the flash memory (IC601). The flash
memory has a capacity of 32M-bit that contains the trans­ceiver control program for the ASIC and stores the data. It
also stores the data for transceiver channels and operating
parameters that are written by the FPU. This program can
be easily written from external devices. The SRAM has a
capacity of 1M-bit that contains work area and data area.

Flash memory

■

Note: The fl ash memory stores the data that is written by
the FPU (KPG-141D), tuning data (Deviation, Squelch, etc.),
and firmware program (User mode, Test mode, Tuning
mode, etc.).

SRAM (Static memory)

■

Note: The SRAM has a temporary data area and work area.

CIRCUIT DESCRIPTION

6-3. LCD

The LCD is controlled using the 4 serial lines (SDI0, /

LCDCS, SCK0, SDO0) from the ASIC (IC610).

6-4. Key detection circuit

Keys are detected using the LCD controller driver IC (IC8).
If a pressed key is detected by IC8, it is informed to IC610
through the serial line.

6-5. Low battery warning

The battery voltage is divided using R514 and R515 and
is detected by the ASIC (IC610). When the battery voltage
falls below the voltage set by the Low battery warning ad­justment, the red LED blinks to notify the operator that it is
time to replace the battery. If the battery voltage falls even
more (approx. 5.8V), a beep sounds and transmission stops.

Low battery warning Battery condition

The red LED blinks during
transmission.

The red LED blinks and the
warning tone beeps while the
PTT switch is pressed.

The battery voltage is low but
the transceiver is still usable.

The battery voltage is low and
the transceiver is not usable to
make calls.

6-6. DSP

The DSP circuit consists of a DSP (IC603) and processes
the baseband signal. The DSP operates on an external clock
of 18.432MHz (the same as the IC610), the I/O section op­erates at 3.3V and the core section operates at 1.5V. The
DSP carries out the following processes:

• 4 Level FSK processing

• Analog FM pre-emphasis/de-emphasis

• Vocoder processing between audio codec and modula-

tion/demodulation

• CAI processing, such as error correction encoding

• QT/DQT encoding/decoding

• LTR encoding/decoding

• DTMF encoding/decoding

• MSK encoding/decoding

• 2-tone encoding/decoding

• 5-tone encoding/decoding

• Compressor/expander processing

• Voice scrambler processing

• Transmit/receive audio fi ltering processing

• Microphone amplifi er AGC processing

• Audio mute processing

• Modulation level processing

7. Power Supply Circuit

The battery voltage (+B) is provided from the battery
terminal on the TX-RX unit (X57). The battery voltage passes
through the 2.5A fuse (F1), and goes to the RF fi nal ampli­fi er, AVR ICs (IC504, IC902), DC/DC converter (IC506), and
voltage detector IC (IC507). The voltage detector watches
the battery voltage. If the battery voltage is 5.6V or higher,
the detector outputs High.

When the VOL SW is turned on, SB1 becomes high (bat­tery voltage). DC/DC (IC506) operates if both SB1 and the
output of the detector are high. IC506 outputs 3.8V and
activates IC502 (33M), IC503 (15M), IC501 (33A) and IC505
(33C). As a result, the ASIC and DSP operate.

The SBC signal becomes High after the ASIC operates,
IC504 (50C), IC902 (50V) and Q501 (SB2) are turned on.

When the /SAVE signal becomes High, Q512 (50C) oper­ates. Switches (Q503, Q505) are controlled by the ASIC.
Q505 (50T) is turned on in transmit mode. Q503 (50R) is
turned on in receive mode.

When the VOL SW is turned off, the /PSW signal be­comes Low. After detecting the /PSW signal, the ASIC
changes the SBC signal to Low.

50C is fed to IC509 (100C). IC509, D511 and D512 con­sist of a voltage doubler. C543 is charged to 5V by 50C and
switched to C545 by the “DDCLK” control signal. The 100C
circuit then outputs approximately +10VDC.

8. Signaling Circuit

8-1.

Encode (QT/DQT/LTR/DTMF/2-tone/5-tone/MSK)

Each signaling data signal of QT, DQT, LTR, DTMF,
2-tone/5-tone and MSK is generated by the DSP circuit, su­perimposed on a modulation signal and output from IC610.
Each deviation of the TX QT, DQT, LTR, DTMF, 2-tone/5-tone
and MSK tone is adjusted by changing the output level of
IC603 and the resulting signal is routed to the VCO and PLL.

8-2.

Decode (QT/DQT/LTR/DTMF/2-tone/5-tone/MSK)

The audio signal is removed from the FM detection signal
sent to the DSP circuit and the resulting signal is decoded.

9. Compander Circuit

The term “compander” means compressor and expand­er. The compander reduces noise by utilizing a compressor
and an expander. The transceiver contains a DSP (IC603) to
perform this operation. The transceiver compander can be
turned on or off using the FPU.
