CIRCUIT DESCRIPTION
Recording/Playback Operation
■Recording
The audio signal input from the AI pin (CN1 pin 12) passes
through a buffer amplifier (IC52 2/2) and goes to an anti-
aliasing filter amplifier (IC52 1/2).
The audio signal is amplified by approx. 30 times by IC52
1/2 and unwanted signal components exceeding 4kHz are
cut by an LPF.
The amplified audio signal is input to pin 78 of the MCU
(IC2 : Micro Controller Unit).
The MCU converts the audio signal to a digital data (by
8kHz/8-bit sampling) and writes it into a flash memory (IC3,
IC5).
When the input level of the AI pin is 100mVp-p, the MCU
input becomes approx. 3Vp-p, and the maximum S/N can be
achieved.
If a signal exceeding 100mVp-p is input to the AI pin, it is
clipped by IC52 so that the MCU input does not exceed 3Vp-
p to protect the MCU against over-voltage input.
■Playback and Prerecorded Voice
The audio signal saved in flash memory (IC3, IC5) is con-
verted to an analog signal by the MCU (IC2) and output as a
playback signal from pin 84.
This playback signal passes through two LPFs to cut har-
monic components and is input to the attenuator circuit.
The attenuator circuit consists of analog switch ICs (IC53,
IC54) and division resistors (R64, R66, R67, R71, R72).
The signal attenuated by the attenuator circuit is con-
verted to a low impedance by an output buffer (IC55), then
output from the AO pin (CN1 pin 11).

■Attenuator Circuit
An attenuator circuit with division resistors is built by con-
trolling four analog switches of IC53 and IC54 with pins 95 to
98 of the MCU (IC2).
The output level is changed in 8 steps with 4-bit data.

I/O Ports
The VGS-1 is a 3V system unit, but it can be adapted to
both 3V and 5V systems for external connection devices with
an 8-bit CMOS bus switch (IC57).
IC57 can convert levels from 3V to 3V, from 3V to 5V, or
from 5V to 3V.
■If the External Device is a 3V System
It can be connected without a pull-up resistor.
■If the External Device is a 5V System
If the external connection device is a 5V system, the VGS-
1 output ports (BUSY, SO, PLAY) must to be pulled up to 5 V.
The waveform may become irregular due to IC57 output ca-
pacity and pull-up resistance.
BUSY and PLAY are Hi/Lo logic output ports and are not
much affected by pull-up resistance.
Even when 3V or 5V is input to an input port, the IC57
output is 3V.
• UART Control
For UART control, the maximum communication speed is
115200 bps, and SO pull-up resistor recommends approx
10kΩ.
• Synchronous Control
SO is not used for synchronous control.
Only PLAY and BUSY must to be pulled up.

■AI Input Port
If input exceeds 100mVp-p, the input signal is clipped and
distortion occurs.
It is necessary to make setting so that no signals exceed-
ing 100mVp-p are input.
If the input level lowers, S/N decreases, so the maximum
input not exceeding 100mVp-p must be used.
■AO Output Port
When recording is performed with a 100mVp-p input, the
playback output becomes an approx. 2.8Vp-p level.
If Prerecorded Voice is generated, the output is approx
2Vp-p.
Beat Shift Circuit
To prevent VGS-1 clock oscillation for the MCU (IC2) from
causing spurious reception to transceivers to which VGS-1 is
connected, the clock oscillator (11.0592MHz) has a beat shift
circuit with a transistor switch (Q1).
■Beat Shift Circuit Off
Pin 94 of the MCU (IC2) goes Low level, Q2 turns off, and
Q1 turns on because a 5V bias is applied to its base. In this
condition, C10 is shorted, so the oscillation frequency is un-
changed.
■Beat Shift Circuit On
Pin 94 of the MCU goes High level, Q2 turns on, and Q1
turns off because its base is pulled down to GND. In this
condition, C10 is connected in series to the crystal oscillator
and the oscillation frequency increases by approx. 150ppm.
Fig. 4 Beat shift circuit
Amateur Transceiver Identification
The VGS-1 can be set as an amateur transceiver or a Land
Mobile Radio transceiver in the factory.
When it is used as a Land Mobile Radio transceiver, inter-
nal data in the VGS-1 is changed to suit the Land Mobile Ra-
dio transceiver, so it cannot be used as an amateur trans-
ceiver.
The VGS-1 set as a Land Mobile Radio transceiver can be
identified because the RV4 land on the PCB is at High level.
The default is Low level.
