The SSE 5000 portable radio operates in the UHF Range 2 (450–488 MHz) frequency band. It can
be programmed with up to 96 channels. Earlier versions of the radio, which could be programmed
with up to 48 channels, can be upgraded to 96-channel capability via FLASHport
1.2FLASHport
The SSE 5000 radio utilizes Motorola’s FLASHport technology. FLASHport allows you to add
software that drives the radio’s capabilities, both at the time of purchase and afterwards. Previously,
changing a radio’s features and capabilities meant significant modifications, or buying a new radio.
Now the radio’s features and capabilities can be upgraded with FLASHport software, similar to how a
computer can be loaded with different software. For information on upgrading the radio’s features
using FLASHport, see the FLASHport User Guide (Motorola publication part number 6881094C35).

Chapter 2Theory of Operation
This chapter provides a detailed circuit description of the SSE 5000 transceiver and VOCON boards.
When reading the theory of operation, refer to the appropriate schematic and component location
diagrams located in the back of this manual. This detailed theory of operation can help isolate the
problem to a particular component.
The SSE 5000 radio is a dual-mode (digital/analog), microcontroller-based transceiver incorporating
a digital signal processor (DSP). The microcontroller handles the general radio control, monitors
status, and processes commands input from the keypad or other user controls. The DSP processes
the typical analog signals, and generates the standard signaling digitally to provide compatibility with
existing analog systems. In addition, the DSP provides digital modulation techniques, utilizing voice
encoding techniques with error correction schemes. This provides the user with enhanced range and
audio quality, all in a reduced bandwidth channel requirement. It allows embedded signaling, which
can mix system information and data with digital voice to support a multitude of system features.
The SSE 5000 radio operates within the UHF range (450 to 488 MHz).
2.1Major Assemblies
The SSE 5000 radio includes the following major assemblies (see Figure 2-1):
• VOCON Board — contains a dual-core processor which includes both the microcontroller unit
(MCU) and a digital signal processor (DSP) core, the processor’s memory devices, an audio
and power supply support integrated circuit (IC), a digital-support IC, and the audio power
amplifier.
• Transceiver (XCVR) Board — contains all transmit, receive, and frequency generation
circuitry, including the digital receiver back-end IC and the reference oscillator.
This section provides an overview of the radio’s receive and transmit operation in the analog mode.
2.2.1Receiving
When the radio is receiving (see Figure 2-2), the signal travels from the antenna connector to the
transceiver board, passing through the antenna switch and the receiver front-end. The signal is then
filtered, amplified, and mixed with the first local-oscillator signal, generated by the voltage-controlled
oscillator (VCO).

Figure 2-2. Receiver Block Diagram
The resulting intermediate frequency (IF) signal is fed to the IF circuitry, where it is again filtered and
passed to the Abacus III digital back-end IC. In the digital back-end IC, the IF signal is mixed with the
second local oscillator to create the second IF at 2.25 MHz. In the back-end IC, a bandpass, sigmadelta, analog-to-digital converter then decodes the second IF signal, and outputs, on the radio’s
serial synchronous interface (SSI) bus, digital audio to the VOCON board.
On the VOCON board, the dual-core processor’s digital-signal processor (DSP) digitally filters the
PCM audio. The DSP decodes the information in the signal and identifies the appropriate destination
for it.
• For a voice signal, the DSP will route the digital voice data to the CODEC inside the audio and
power supply support IC, for conversion to an analog signal. The CODEC will then present the
signal to the receive audio pre-amplifier, then to the audio power amplifier, which drives the
speaker.
• For signaling information, the DSP will decode the message and pass it internally to the
microcontrol unit of the dual-core processor.
November 11, 20046881094C12-A
Theory of Operation: Mode of Operation2-3
2.2.2Transmitting
When the radio is transmitting, microphone audio is passed through gain stages to the CODEC,
where the signal is digitized (see Figure 2-3). The CODEC passes digital data to the DSP, where preemphasis and low-pass (splatter) filtering are done. The DSP passes this signal to a digital/analog
converter (DAC), where it is reconverted into an analog signal and scaled for application to the
voltage-controlled oscillator as a modulation signal.

Transmitted signaling information is applied to the DSP from the microcontrol unit, where it is coded,
and passed to the DAC, which handles it the same as a voice signal. The DAC output connects to
the synthesizer modulation input. A modulated carrier is provided to the transmitter power amplifier,
which transmits the signal under dynamic power control.

2.3.1DC Power Routing—Transceiver Board
Connector J1, the B+ assembly, connects the battery to the transceiver board. Two capacitors
provide protection against momentary breaks at the B+ connector due to contact bounce when the
radio is dropped.
An RF bead forms a power-line filter for signal RAWB+, which supplies battery voltage to the
transmitter PA.
A transistor, controlled by signal SWB+ from the VOCON board, turns on XB+, which supplies the
5-V linear regulator, TX_ALC block and SW_FL.
Fuse F901 and a filter supply fused B-plus to the VOCON board. In turn, the VOCON board supplies
VSW1, regulated 3.8 Vdc, from the Global Control Audio and Power (GCAP) switching regulator to
the XCVR. A switch, controlled by SWB+, turns on V38 to the XCVR 3-V linear regulators. The
XCVR regulated power supplies are summarized inTable 2-3.

Description
2.3.2DC Power Routing—VOCON Board
Raw B+, or unswitched B+, (UNSW_B+) is routed to connector J1 on the transceiver board, and then
on to P201 on the VOCON board. Here the UNSW B+ is forwarded to the radio’s control top
On/Off/Volume knob through connector J707 and a flex circuit, as well as to regulator U505 (VCC5).
The On/Off/Volume knob controls B+SENSE to a BJT switch, which in turn controls a power
MOSFET. The MOSFET is a solid-state power switch that provides SW B+ to the VOCON board, the
audio PA, the GCAP II IC (via GCAP_B+), and back to the transceiver board.
In the case of a secure radio model, SW B+ and UNSW B+ are also supplied to the encryption
module through connector J701.
The BJT switch is also under the control of the MCU via Vref from the GCAP II IC (U501). This allows
the MCU to follow an orderly power-down sequence when it senses that B+SENSE is off. This sense
is provided through MECH_SW_BAR (inverted B+SENSE).
The digital circuits in the VOCON board are powered from regulators located in the GCAP II IC
(U501), an external 5 Vdc regulator (VCC5, U505), and an external 1.55 Vdc regulator (VSW_1.55).
The GCAP II IC provides three supplies: VSW1, VSW2, and V2. These regulators are software
programmable.

2.4Transceiver Board
The transceiver (XCVR) board performs the transmitter and receiver functions necessary to translate
between voice and data from the VOCON board and the modulated radio-frequency (RF) carrier at
the antenna. The transceiver board contains all the radio’s RF circuits for the following major
components:
• Receiver
• Transmitter
• Frequency Generation Unit (FGU)
2.4.1Interconnections
This section describes the various interconnections for the transceiver board.
2.4.1.1 Battery Connector J3
Battery connector J3 consists of three gold-plated contacts on the printed circuit board that mate with
a B-plus connector assembly. Signal descriptions are in Table 2-5.

2.4.1.2 VOCON Connector P1
VOCON connector P1 (located on the XCVR board) consists of 26 gold-plated pads for the 26-pin
compression connector, and one plated tool hole (pin 27) used for connector alignment. This is a
digital interface carrying DC power, control, and data between the XCVR and VOCON boards. P1
connects through the compression connector to P201 on the VOCON board.
Table 2-6 lists the connector pins, their signals, and functions. SPI refers to the serial peripheral
interface, which is the control bus from the microprocessor. SSI is the serial synchronous interface
bus for data to and from the DSP. There is a RX SSI bus for demodulated data from the receiver and
a TX SSI bus for modulation data to the transmitter.

2.4.1.3 Antenna Ports
Antenna port J101 is a hot launch connector that interfaces to the antenna connector that is part of
the control top. This interface provides the launch mechanism for the antenna. Antenna port J102
provides RF to the accessory RF connector on the back of the SSE 5000 radio. This port provides
RF energy for tuning purposes, as well as RF for a public safety microphone.
2.4.1.4 Serial EEPROM
The serial, electrostatically erasable, programmable, read-only memory (EEPROM) has the
reference designator U4 on the SSE 5000 transceiver board. This IC holds all of the transceiver
tuning data. This allows transceivers to be tuned in the factory and installed in the field without
retuning.
