6FUNCTIONAL DESCRIPTION
6.1PCF26100 overview
The adapter features a Power-on reset which is used to
reset the adapter logic. There is also a POR_EXT signal
which is used for controlling the reset of the PCF26100
within the application.
The system clock for the application is generated by the
PCF26100. The system clock is then provided to the
baseband SYS_CLK and the radio REF_CLK. Both the
SYS_CLK and REF_CLK clocks are controlled within the
PCF26100.
From the system clock a low-power 3.2 kHz clock
LPO_CLK is generated.
From the PCF26100 a 1 MHz TX_CLK is generated to be
used in the baseband controller to clock out the transmit
data on TX_DATA.
The serial interface to the baseband controller is a JTAG
interface. This interface is used toinitialize and control the
PCF26100 and subsequently the radio. The channel
information received from theJTAG interface is converted
and forwarded to the radio 3-wire S-bus interface.
The timing control signals to the UAA3558 radio are
generated in the PCF26100. For this a minimum number
of reference timing signals from the baseband controller
are used. The exact timing of the control signals is
programmable in the PCF26100.
The PCF26100 converts the digital transmit data from the
baseband controller to analog gaussian shaped transmit
data to the radio.
The analog RSSI from the radio is converted to digital and
made available to the baseband controller via the JTAG
interface.
The digital power amplifier control information
communicated from the baseband controller to the
PCF26100isconvertedto an analog control voltageforthe
radio.
The PCF26100 provides an identification number, which
can be read by the baseband controller through the JTAG
interface.
For frequency compensation and tuning, the PCF26100
provides a tuning capability on the system oscillator.
The timing for the radio is generated in the PCF26100 using a minimal number of baseband signals. The channel
programming is received from the JTAG serial interface. The SYNTH_ON signal is used to determine the start and end
of the packet. The radio SLCCTR signals is also controlled with PX_ON.

6.3.1T_GFSK
The T_GFSK data output has 3 phases:
1. Idle phase
2. DCbias phase
3. Txdata phase.
The Idle phase is used outside transmit packets. In this
phase the T_GFSK output state is defined by the
‘gfsk float’ bit in the Enable Register.If the ‘gfsk float’ bit is
set to a logic 0, the T_GFSK output is pulled to ground; if
set to a logic 1 the T_GFSK output is floating.
The DCbias phase is used during the transmit slot as
start-up phase before the transmit data. The DCbias
phase is activeGFSK_DC_BIAS_Start delayfollowing the
S_EN rising edge until the first transmit data bit on
TX_DATA.
During this phase a DC bias is generated by the GFSK
filter, which is achieved by selecting the GFSK table
mid-value as the output of the GFSK filter.
The Txdata phase is used when TXDATA is present.
In this phase the TX_DATA is fed into the GFSK filter. The
presence of TXDATA is determined by detecting the first
TXDATA edge. The end of the TXDATA is detected by the
end of packet from the baseband controller. To not lose
TXDATA information in the T_GFSK output, due to the
data detection, the data from the GFSK input is delayed
with 1-bit.
The T_GFSK output requires an external low-pass filter.
Thereference voltage for theT_GFSKcomes directly from
the V
relation to a variation in the T_GFSK levels. The V

The TX_CLK output is activated during the DC_BIAS

6.3.2RESET
The PCF26100 is reset with a Power-on reset using the
VIO_POWER signal. This will reset all registers and put
the device into a known state. The POR_EXT reset signal
will also resetthe device andput it inthe same state as the
Power-on reset. However, POR_EXT is intended to be
used for a reset from a host.
Following the Power-on reset or areset by POR_EXT, the
system oscillator is started and the SYS_CLK output is
activated (enabled). The SYS_CLK output can be
controlledbythe SYS_CLK_REQ signal butonlyifthe ‘rdy’
bit in the Control Register has been set to logic 1.

SYS_CLK_REQ
The function of SYS_CLK_REQ has 2 phases:
1. After reset, SYS_CLK_REQ is not taken into account
forthegenerationof SYS_CLK. After reset the13 MHz
system clock is enabled on SYS_CLK.
2. Once the ‘rdy’ bit is set to logic 1, the 13 MHz clock on
the SYS_CLK is controlled with SYS_CLK_REQ.
The SYS_CLK_REQ signal will not control or disable the
oscillator.
The LPO_CLK output is only controlled by the POR_EXT
signal which also controls the POR output. The POR is
activated 4 SYS_CLK cycles after POR_EXT.

6.4Serial interface
6.4.13-WIRE S-BUS
The 3-wire S-bus at the radio side is a 32-bit serial interface which is used for control, TX/RX and channel information.
The 32-bit definition is given in Tables 4 and 5.
Bits 31 to 9 arestatic values and will not change dynamically,the value for these bitscome fromthe static registers. Only
thetrx and main dividerfields will control theUAA3558on a slot-by-slotbasis.The trx andmaindivider information comes
fromthe baseband controllerserial interface channelword;see Section 6.5.1. However,the baseband controllerchannel
information needs a conversion to get the correct main divider information for the UAA3558.

6.4.2JTAG
The JTAG serial interface is usedto control the PCF26100 and subsequently the radio. ThePCF26100 must be the only
slave on the JTAG bus as the PCF26100 does not allow for multi-slave operation. The JTAG interface protocol used is
fully compliant with the standard set out in
• 5-bit register address
• 8-bit data
• Set instruction register
• Read/write data register (note: some addresses have a separate read and write data register).
TheJTAG interface allowsfor 2 ways ofaccessing a register.One is thecommunicate address anddata, and thesecond
one is for successive accesses to the same registers where only the data is communicated. This can, for example, be
used for updating the channel information before every packet.

The RSSI is read via the serialinterface. TheUAA3558 providesan analog RSSI output. The interface logic converts the
analog RSSI value and stores the result in a serial interface register. The timing for converting the RSSI is programmed
using the RSSI_start register. The RSSI can only be measured starting 10 µs after the S_EN falling edge. The RSSI
value can only be read from the serial interface register after the measurement has been completed, this is at the end of
the packet. RSSI measurements are only done in receive packets.

6.5.7GFSK
TABLE
The values for the GFSK filter are stored in a 13-byte GFSK table. The GFSK table is accessed through a single control
word which is used to store the data in the GFSK table on subsequent writes. To align the writing to the GFSK table a
table address reset bit is available in the Enable register. When the resetbit ‘grst’ in the Enable register is set toa logic 1
the GFSK table address will be reset and the next GFSK control word is written at location 0 in the GFSK table. Every
subsequent write to the GFSK control word will be stored at the next address in the GFSK table. If the last address is
reached, subsequent writes will continue to effect the last address.
The values for the GFSK table depend on the reference voltage on V
. The T_GFSK signal should have a DC_Bias
DDA
of 1.2 V with a peak-to-peak swing of 1 V (amplitude = 0.5 V). For this the values for the GFSK table are calculated as
shown in Table 26.

gfsk = 1, then output floats.
6grstGFSK table address reset. Writing a logic 1 will reset the GFSK table addressing.
5pa floatControls the PA output outside TX packet. If pa float = 0, then output tied to ground. If
pa float = 1, then output floats.

13 SOLDERING
13.1Introduction to soldering surface mount
packages
Thistext gives a verybriefinsightto a complextechnology.
A more in-depth account of soldering ICs can be found in
our
“Data Handbook IC26; Integrated Circuit Packages”
(document order number 9398 652 90011).
There is no soldering method that is ideal for all surface
mount IC packages. Wave soldering can still be used for
certainsurfacemount ICs, but itisnotsuitable for fine pitch
SMDs. In these situations reflow soldering is
recommended.
13.2Reflow soldering
Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
tothe printed-circuit boardbyscreen printing, stencillingor
pressure-syringe dispensing before package placement.
Several methods exist for reflowing; for example,
convection or convection/infrared heating in a conveyor
type oven. Throughput times (preheating, soldering and
cooling) vary between 100 and 200 seconds depending
on heating method.
Typical reflow peak temperatures range from
215 to 250 °C. The top-surface temperature of the
packages should preferable be kept below 220 °C for
thick/large packages, and below 235 °C for small/thin
packages.
13.3Wave soldering
Conventional single wave soldering is not recommended
forsurfacemount devices (SMDs) orprinted-circuitboards
with a high component density, as solder bridging and
non-wetting can present major problems.
To overcome these problems the double-wave soldering
method was specifically developed.
If wave soldering is used the following conditions must be
observed for optimal results:
• Use a double-wave soldering method comprising a
turbulent wave with high upward pressure followed by a
smooth laminar wave.
• For packages with leads on two sides and a pitch (e):
– larger than or equal to 1.27 mm, the footprint
longitudinal axis is preferred to be parallel to the
transport direction of the printed-circuit board;
– smaller than 1.27 mm, the footprint longitudinal axis
must be parallel to the transport direction of the
printed-circuit board.
The footprint must incorporate solder thieves at the
downstream end.
• Forpackageswith leads on foursides,thefootprint must
be placed at a 45° angle to the transport direction of the
printed-circuit board. The footprint must incorporate
solder thieves downstream and at the side corners.
During placement andbefore 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.
Typical dwell time is 4 seconds at 250 °C.
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
13.4Manual soldering
Fix the component by first soldering two
diagonally-opposite end leads. Use a low voltage (24 V or
less) soldering iron 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.

13.5Suitability of surface mount IC packages for wave and reflow soldering methods
1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum
temperature (with respect to time) and body size of the package, there is a risk that internal or external package
cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the
Drypack information in the
2. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink
(at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version).
3. If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave direction.
The package footprint must incorporate solder thieves downstream and at the side corners.
4. Wave soldering is only suitable for LQFP, TQFP and QFP packages with a pitch (e) equal to or larger than 0.8 mm;
it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.
5. Wave soldering is only suitable for SSOP andTSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is
definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
