PCD5041
FUNCTIONAL DESCRIPTION (see Fig.1)
6.2
The PCD5041 has dedicated hardware blocks containing
logic for time-critical functions requiring bit or byte-time
accuracy. Other functions requiring only slot-time
accuracy are performed by software in the Programmable
Communication Controller (PCC). This approach offers
maximum flexibility during prototyping.
6.1
6.1.1
The device has an on-chip 13.824 MHz crystal oscillator.
From this source, a few frequencies are derived for internal
and external use. Frequencies generated for external use
are:
• 13.824 MHz for the synthesizer reference
(pin REF_CLK). This output is only provided if the
synthesizer power-down control (output on
pin S_POWER_DWN) is not selected.
Internal bus and data memory
• 0.144 to 13.824 MHz for the microcontroller clock
(pin PROC_CLK)
INTERNAL BUS
The function of the internal bus is:
• 3.456 MHz for the ADPCM CODEC (pin CLK3)
• To provide access for all functional blocks to the
common data memory
• 1200 Hz (pin 1200_HZ) for dual synthesizer switching
• 100 Hz (pin CLK100) indicates start of frame.
• To provide access for the microcontroller-interface and
the PCC to all other functional blocks.
Nominally, the frequency on pin CLK3 is 3.456 MHz. This
frequency is obtained by dividing the crystal frequency by
4. Sometimes, the crystal frequency will be divided by 3
or by 5, to synchronize the combination of the ADPCM
CODEC and the device to an external source. For the
handset application, the PCD5041 can be synchronized to
the incoming radio channel, using the ‘slot
synchronization’ event of one active channel, so the
handset is locked to one base station.
All functional blocks (speech-interface, RF-interface,
microcontroller-interface and PCC) can autonomously use
the internal bus to communicate with the common data
memory.
A bus controller is used to handle the bus priority
mechanism. When several blocks request access
simultaneously, the request with the highest priority is
handled first.
6.1.2
DATA MEMORY
A large part of the data memory is used for the bit rate
adaptation between the DECT radio interface and the
speech interface. The data memory also acts as the main
communication interface between the external
microprocessor and the PCC.
In a handset, the device uses only 1 kbyte of the common
data memory. The remaining 1 kbyte can be used by the
microcontroller as an extended data memory for the higher
layer software. The microcontroller is not aware of the fact
that it is sharing the memory with the PCD5041. From the
microcontroller’s point of view, the PCD5041’s
microcontroller-interface plus the common data memory
behave as a standard RAM device.

Programmable communication controller and
program memory
6.4
The speech interface block performs the following
functions:
PCC
• Connection to a 1152 kbit/s interface in a handset and a
simple base station in the so called ‘12 slot mode’
The PCC is a RISC-type controller and is used to control
functions which are slot-time accurate. It is well suited for
bit manipulation, and runs at a clock frequency of
6.912 MHz (equivalent to 3.4Mips). After finishing a task, it
switches to a power saving state, from which it returns
after a pre-programmed time.
6.3.2
• Autonomous storing/fetching of ADPCM speech data
in/from the PCD5041’s common data memory, using
internal addressing logic
• Muting of speech data
• Local call.
PCC FUNCTIONS
The most important functions of the PCC are to:
6.4.1
• Perform the appropriate actions on received messages:
PMID and FMID checking, RFPI checking, TBC
handling
12-SLOT MODE
This is the normal operating mode for the PCD5041.
The 12-slot mode is selected if up to 4 ADPCM CODECs
are connected to the PCD5041, where the PCD5041 is the
master of these CODECs. In a handset, or in a simple
base stations which is connected with up to 4 analog lines
to the public network, the PCD5041 is master of the
CODECs. Each CODEC is connected with a separate
framing reference signal (FS1 to FS4) to the PCD5041.
In the QFP64 package, 2 framing signals FS1 and FS2
are available, whereas in the LQFP80 package 4 framing
signals can be used (FS1 to FS4). When more CODECs
• Prepare A-field messages for transmission
• Prepare the RF-interface for the coming slot
• Perform the procedures for RSSI and set-up scan,
maintain scan counters and timers, assemble the RSSI
field in the common data memory
• Filter events and indicate them to the microcontroller by
interrupt.

are to be connected, the FS5 to FS12 signals have to be
generated externally. When using the framing signals
FS1 to FS4, no interface logic is required when using the
PCD5032 ADPCM CODEC.
6.5
Most of the functions performed by the RF interface are
under control of the PCC. Specifically, the processing of
non-speech data and the programming of functions and
registers is done via the PCC.
A speech-slot control table is used to determine where to
store/fetch speech data for transmission and reception.
The hardware speech-interface is capable of addressing
the right speech buffer for the relevant speech slot, and will
maintain a counter carrying the offset to the correct
stored/fetched address.
6.4.2
6.5.1
MUTING
The serial receiver will collect the complete A-field and
B-field and store it in the common data memory. Before the
A-field is received, the A-field start address is programmed
by the PCC. Upon reception of A-field nibbles, the address
is updated by the serial receiver. Meanwhile, the PCC will
program the B-field start address.
• Fast muting
In Fig.6 the data flow in the serial receiver is shown. Note
that almost no decoding of messages is required. Only the
header of the A-field needs to be decoded to check if a
ciphered message is being received or transmitted, which
requires the ciphering to be switched on in the A-field also.
• Slow muting.
Fast muting, which is performed by the PCD5041
automatically, is nothing more than a repetition of the
previously received frame (80 speech samples) to the
ADPCM CODEC. It is issued if no Sync word was
detected. Slow muting is issued by the microcontroller,
after having detected a degradation of quality. A slow mute
is implemented as a continuous ‘0000’ nibble transmission
to the ADPCM CODEC, until slow mute is released.
6.5.2
A local call option is implemented, in order to loopback
data from one CODEC to another CODEC, and vice versa,
see Fig.5.
By transmitting the X-CRC twice, the Z-field is transmitted.
The handling of the address registers is the same for the
transmitter. Transmission of the synchronization sequence
(S-field) is done using the same method as the A-field and
B-field. The S-field is stored in the common data memory
and will be fetched by the transmitter, just before
transmission.

SERIAL RECEIVER
The serial transmitter performs the reverse of the receiver
functions. Several blocks used in the receiver are also
used in the transmitter. Amongst these are the
CRC-generators, the scrambler, and the address
registers. Figure 7 shows the serial transmitter structure.
LOCAL CALL
0
SERIAL TRANSMITTER
The serial receiver processes the data, which comes from
the RF section, and which is already filtered by the
synchronization part. The data is latched, using the
recovered data clock.
Due to various reasons the quality of the incoming speech
data may be degraded significantly. By muting the speech
data, these disturbances are not audible (or are less
audible) to the user. The PCD5041 performs two types of
muting:

PCD5041
To program various types of synthesizers, a 3-byte shift
register is present. Three data formats are supported:
8, 16 or 24 bit words can be selected. The transfer of data
from a frequency table in the common data memory to the
shift register is under control of the PCC.
SEAMLESS HANDOVER
Seamless handover guarantees that when speech
information is switched from one slot to another, no speech
samples are lost, added or displaced. Seamless handover
is achieved in the RF interface by:
• Using a look-up table containing the correct start
addresses of the B-fields in the data memory
6.5.6
The RSSI measurement in the PCD5041 RF-interface
block is done in 3 parts: a peak/hold detector, a 6-bit A/D
converter, and an RSSI control unit, which controls the
peak/hold detector and the A/D converter. Once per slot
time, a sample is fetched by the PCC and saved in the
appropriate area of the common data memory.
• The RF receive and transmit blocks move data to/from
the data memory block in 4-bit nibbles.
6.5.4
RF CONTROL SIGNALS
The timing of the control signals to the RF section is fixed,
but such that an RF delay between 1.5 and 7 µs can be
tolerated. Only the transmitter ramp signal and the
synthesizer enable are programmable within certain limits.
6.5.5
RSSI MEASUREMENT (see Fig.8)
If the radio receiver is active in a particular time slot, the
RSSI value will automatically be measured in that slot.
Adjustment to the RSSI_AN input level can be made with
VREF.
SYNTHESIZER PROGRAMMING
To program a synthesizer, a 3-wire serial interface is used.
The signals on this interface are:
• S_ENABLE (enable)
• S_CLK (clock)
• S_DATA (data).

PCD5041
Bit synchronization is done using a Digital PLL (DPLL),
with an oversampling factor of 12, i.e. the DPLL is running
at 12 times the data rate. The output from the DPLL is a
receive clock signal (RxC), which acts as the enable for a
20-bit shift register.
LOCAL CALL SWITCHING (see Fig.9)
The PCD5041 provides a local call switching function in
the base station. It stores incoming speech nibbles in the
common data memory, in the area reserved for that
particular receive slot. Then, during the transmit phase, it
passes the start pointer of the same data memory area to
the transmit block. Thus, the speech data is echoed to the
other user. To handle quality degradation for local calls, a
mute can be performed at the RF side of the speech buffer.
6.5.8
Sync word detection is achieved by checking the incoming
data pattern with the expected synchronization field
pattern, using a correlator.
The correlator has a programmable threshold, so it can
accept bit errors in the sync field pattern up to the
threshold level. Furthermore, the correlator window is
programmable. This means that ‘SlotSync’, which
indicates the slot synchronization event, can be detected
only during a certain period (the time window).
DATA SYNCHRONIZATION (see Fig.10)
The data synchronization is done in 2 phases:
• Bit synchronization
• Sync word detection.

The ‘DPLL_sync’ indication should only be used, when
‘SlotSync’ is active. It indicates that the last 4 bits of the
pre-amble field (the training sequence) are received
correctly, and thus indicates that the DPLL was in lock
(synchronized) in time. If the ‘SlotSync’ is active, and the
‘DPLL_sync’ is not, then a sliding interferer might have
been detected.
automatically by the cipher machine. The contents of the
memory space where IV and key are found, are the
responsibility of the PCC, and the external
microprocessor.
6.5.10
The PCD5041HZ contains a comparator/data slicer.
The comparator is a stand-alone circuit. No connections
other than power supply are made internally. The
comparator can be used as a data slicer for the receiver
input. The delay requirements listed in Chapter 8 were
derived from this application. Another use of the
comparator is in a successive approximation A/D
converter to indicate battery low-voltage condition, or in a
power-on-reset circuit.
If ‘SlotSync’ is not detected, effectively no data is received
in that slot. This implies a ‘fast mute’ because speech data
received in the previous frame is not destroyed.
6.5.9
CIPHERING MACHINE
The description of the cipher machine is subject to
confidentiality. The specification of its algorithms are
delivered by ETSI under the terms of a Non-Disclosure
Agreement.
When the signal COMP_NE is LOW the comparator is
enabled. When COMP_NE is HIGH the comparator is
disabled, and the circuit consumes no power. If the
comparator is used as a data slicer for the receiver input,
the R_DATA is connected to COMP_OUT, the COMP_NE
is connected to R_ENABLE, both connection are done
externally. The pin COMP_INP is connected to the RF
mixer. A proper bias voltage (from the slicer time constant
control circuit) is connected to COMP_INM. Another use of
the comparator is in a successive approximation A/D
converter for battery voltage detection.
The cipher machine is under control of the TBC, which is
implemented in the PCC. The cipher machine generates
2 fields of ciphering bits:
• A_cipher (40 bits) for A-field messages (ciphers tail
only)
• B_cipher (320 bits) for speech in B-field.
The transmitted ciphered bits are then:
• A_ciphered: = A XOR A_cipher
• B_ciphered: = B XOR B_cipher.
The pins are protected against ESD damaging, with a
protection diode to the positive and negative supply rail.
The input pin COMP_NE has a pull-up resistor which
keeps the comparator in power-down mode by default.
On reception by the peer end point, deciphering consists
of the same operation thanks to the synchronous
generation of A_cipher and B_cipher.

Microcontroller Interface
The PCD5041 is equipped with a watchdog timer, which
generates a reset towards an external device (e.g. a
microcontroller) after time-out. Two (fixed) time-out
periods can be programmed; 1.25 s and 82 s.
The watchdog function can be disabled by using the
EN_WATCHDOG input pin.
FUNCTION OF THE MICROCONTROLLER INTERFACE
The microcontroller interface will provide the following
services.
• Direct interface to processors which have an
INTEL-8051 compatible interface
• General interface to processors that can handle ‘wait
states’ e.g. 68000-family; in this case glue logic is
required
6.6.4
• A programmable interrupt register
• A watchdog timer with time-out periods of
1.25 or 82 seconds, depending on the programming.
The 13.824 MHz clock is never switched off. The Timing
Control, microcontroller interface, and Bus Controller keep
running, in order to remain synchronous with a base
station, and to keep the wake-up circuitry active. During
power-down the external microcontroller has still access to
the common data area.
The microcontroller can address the PCD5041 as any
other RAM memory connected to the microcontroller bus.
By writing the ‘Interface-Mode Register’, the
microcontroller can select the interface mode and its own
clock frequency.
6.7
MICROCONTROLLER INTERRUPTS
Survey of registers
For a survey of all addresses occupied refer to
Tables 1 and 2. Some of the address locations are used
differently for read and write. The addresses 000 to 7DF
are occupied by RAM memory, while the upper 32 bytes
are assigned to the hardware registers. A part of the RAM
memory is allocated for use by the RF block, cipher block,
and the speech interface.
The function of microcontroller Interrupts is to make
optimal use of the microcontroller’s processing power, and
to achieve optimal cooperation between time-critical tasks
and less time-critical tasks both executed in software.
Three registers are available to handle interrupts. These
are:
• Interrupt Event Register
• Interrupt Enable Register
• Interrupt Reset Register.
These registers are to be regarded together.
Corresponding bits in these registers relate to one and the
same event. Bits in the Interrupt Event Register are set by
the PCC and are to be reset by the external processor by
writing ‘1’s in the corresponding bits in the Interrupt Reset
Register. The mask in the Interrupt Enable Register
enables the interrupt if corresponding events do occur.
1996 Oct 31
POWER-DOWN
The PCC may switch off the 6.912 MHz internal clock, to
enter a power saving mode. All blocks, running on this
clock are then switched off (i.e. RF-interface, cipher block,
speech interface, PCC). This is called the power-down
state, and is only used in the handset mode.
• Processor clock signal of which the frequency is
programmable in order to adjust instantaneously

Notes to the characteristics
1. VDD = 3.0 V; fclk =13.824 MHz; no external load; one speech link active (under typical conditions).
2. VDD = 3.0 V; fclk =13.824 MHz; no external load; after reset.
3. Maximum differential non-linearity at supply voltage 5.5 V and VREF = 1 V.
4. Supply current IDD(stb)(comp) flows when COMP_NE is HIGH.
Supply current IDD(idle)(comp) flows when the comparator is in active mode (COMP_NE is LOW). It is the DC current
of the comparator when it is not switching, and V(COMP_INP) < V(COMP_INM).
The active mode supply current IDD(1MHz) includes the output pulse rate of 1 MHz.
5. For input pins COMP_INP, COMP_INM, COMP_NE.
6. For input pin COMP_NE.
7. The minimum input common mode voltage will be measured at DC levels with, COMP_INM at 1 V DC ±30 mV.
The same goes for the maximum input common mode voltage at (VDD − 0.5V).
8. These values are not tested in production, and are based upon theoretical estimates and laboratory tests.
9. The propagation delay tpd is measured from the time the differential input voltage equals the offset voltage, to the
50% point of the output transition. The initial differential input voltage is 100 mV and the propagation delay is
specified for an input overdrive of 30 mV, and a load capacitance of 50 pF. tpd is valid for both the positive and
negative going output transition. The maximum value is valid for the total ranges of temperature, supply voltage and
common mode input voltage. The worst case operation conditions are at the minimum supply voltage, the lowest
operating temperature and the minimum input common mode voltage. The delay difference ∆tpd gives the difference
between tpd for the rising output transition and tpd for the falling output transition and is valid for all operating
conditions. The test method to check the maximum delay difference is by measuring the RMS voltage of the output
signal.

If wave soldering cannot be avoided, the following
conditions must be observed:
10 SOLDERING
10.1
Introduction
• A double-wave (a turbulent wave with high upward
pressure followed by a smooth laminar wave)
soldering technique should be used.
There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-hole and surface mounted components are mixed
on one printed-circuit board. However, wave soldering is
not always suitable for surface mounted ICs, or for
printed-circuits with high population densities. In these
situations reflow soldering is often used.
Even with these conditions:
This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our “IC Package Databook” (order code 9398 652 90011).
• Do not consider wave soldering LQFP packages
LQFP48 (SOT313-2), LQFP64 (SOT314-2) or
LQFP80 (SOT315-1).
10.2
• The footprint must be at an angle of 45° to the board
direction and must incorporate solder thieves
downstream and at the side corners.
• Do not consider wave soldering QFP packages
QFP52 (SOT379-1), QFP100 (SOT317-1),
QFP100 (SOT317-2), QFP100 (SOT382-1) or
QFP160 (SOT322-1).
Reflow soldering
Reflow soldering techniques are suitable for all LQFP and
QFP packages.
During placement and before soldering, the package must
be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured.
The choice of heating method may be influenced by larger
plastic QFP packages (44 leads, or more). If infrared or
vapour phase heating is used and the large packages are
not absolutely dry (less than 0.1% moisture content by
weight), vaporization of the small amount of moisture in
them can cause cracking of the plastic body. For more
information, refer to the Drypack chapter in our “Quality
Reference Handbook” (order code 9397 750 00192).
Maximum permissible solder temperature is 260 °C, and
maximum duration of package immersion in solder is
10 seconds, if cooled to less than 150 °C within
6 seconds. Typical dwell time is 4 seconds at 250 °C.
Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
to the printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement.
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
10.4
Several techniques exist for reflowing; for example,
thermal conduction by heated belt. Dwell times vary
between 50 and 300 seconds depending on heating
method. Typical reflow temperatures range from
215 to 250 °C.
Fix the component by first soldering two diagonallyopposite end leads. Use only a low voltage soldering iron
(less than 24 V) applied to the flat part of the lead. Contact
time must be limited to 10 seconds at up to 300 °C. When
using a dedicated tool, all other leads can be soldered in
one operation within 2 to 5 seconds between
270 and 320 °C.
Preheating is necessary to dry the paste and evaporate
the binding agent. Preheating duration: 45 minutes at
45 °C.
10.3
Wave soldering
Wave soldering is not recommended for LQFP or QFP
packages. This is because of the likelihood of solder
bridging due to closely-spaced leads and the possibility of
incomplete solder penetration in multi-lead devices.
