1.3 GHz universal bus-controlled
TV synthesizer
TSA5520; TSA5521
The device has three independent I2C-bus addresses
which can be selected by applying a specific voltage on the
CE input (see Table 5). The general address C2 is always
valid. When the I2C-bus format is fully used, TSA5520 and
TSA5521 are equal.
GENERAL DESCRIPTION
The device is a single-chip PLL frequency synthesizer
designed for TV and VCR tuning systems. The circuit
consists of a divide-by-eight prescaler with its own
preamplifier, a 15-bit programmable divider, a crystal
oscillator and its programmable reference divider and a
phase/frequency detector combined with a charge-pump
which drives the tuning amplifier and the 33 V output.
Four high-current PNP band switch buffers are provided
for band switching. Two PNP buffers can be switched on
simultaneously. The sum of the collector currents is limited
to 50 mA.
3-wire bus format (SW = VCC1 or open-circuit)
Data is transmitted to the device during a HIGH level on
the CE input (enable line pin 15). The device is compatible
with 18-bit and 19-bit data formats. The first four bits are
used to program the PNP band switch buffers and the
remaining bits are used to control the programmable
divider. A 27-bit data format may also be used to set the
charge-pump current, the reference divider ratio and for
test purposes. The difference between TSA5520 and
TSA5521 are given in Table 1.
Depending on the reference divider ratio (512, 640 or
1024), the phase comparator operates at 3.90625 kHz,
6.25 kHz or 7.8125 kHz using a 4 MHz crystal.
The lock detector output is LOW when the PLL loop is
locked. In the test mode, this output is used as a test
output for fref and 1/2fdiv (see Table 6). The device can be
controlled in accordance with the I2C-bus format or the
3-wire bus format depending on the voltage applied to the
SW input (see Table 2).
When the 27-bit format is used, the TSA5520 and
TSA5521 are equal and the reference divider is controlled
by the RSA and RSB bits (see Table 7). More details are
given in Chapter “Functional description” Section “3-wire
bus mode (SW = open-circuit or VCC1); see
Figs 3, 4 and 5”.
I2C-bus format (SW = LOW)
Five serial bytes (including address byte) are required to
address the device, select the VCO frequency, program
the four PNP band switch buffers, set the charge-pump
current and the reference divider ratio.

The first bit of the first data byte transmitted indicates
whether frequency data (first bit = 0) or control and band
switch data (first bit = 1) will follow. Until an I2C-bus STOP
command is sent by the controller, additional data bytes
can be entered without the need to re-address the device.
The frequency register is loaded after the 8th clock pulse
of the second Divider Byte (DB2), the control register is
loaded after the 8th clock pulse of the Control Byte (CB)
and the band switch register is loaded after the 8th clock
pulse of the Band switch Byte (BB).
FUNCTIONAL DESCRIPTION
The device is controlled via the I2C-bus or the 3-wire bus
depending on the voltage applied to the SW input (pin 11).
A HIGH level on the SW input enables the 3-wire bus
inputs which are Chip Enable (CE), serial data input (SDA)
and serial clock input (SCL). A LOW level on the SW input
enables the I2C-bus inputs which are CE [Address
Selection (AS) input], serial data input/output (SDA) and
serial clock input (SCL). The bus format selection is given
in Table 2.
I2C-bus address selection
I2C-bus mode (SW = LOW); see Table 3
The module address contains programmable address bits
(MA1 and MA0) which offer the possibility of having
several synthesizers (up to 3) in one system by applying a
specific voltage to the CE input.
Data bytes can be sent to the device after the address
transmission (first byte). Four data bytes are required to
fully program the device. The bus receiver has an
auto-increment facility which permits the programming of
the device within one single transmission
The relationship between MA1 and MA0 and the input
voltage applied to the CE input is given in Table 5.
(address + 4 data bytes).
The device can also be partially programmed providing
that the first data byte following the address is Divider
Byte 1 (DB1) or the Control Byte (CB). The bits in the data
bytes are defined in Table 3.

occurs. Only RSA is controlled by the transmission length
when the 18-bit or 19-bit format is used.
During a HIGH level on the CE input, the data is clocked
into the data register at the HIGH-to-LOW transition of the
clock pulse. The first four bits control the band switch
buffers and are loaded into the internal band switch
register on the 5th rising edge of the clock pulse.
The frequency bits are loaded into the frequency register
at the HIGH-to-LOW transition of the chip enable line when
an 18-bit or 19-bit data word is transmitted.
A data word of less than 18 bits will not affect the
frequency register of the device. The definition of the bits
is unchanged compared to the I2C bus mode.
The power-on detection threshold voltage VPOR is fixed to
VCC1 = 2 V at room temperature. Below this threshold, the
device is reset to the power-on state described above.
Table 6 Test bits
At power-on the charge-pump current is set to 280 µA, the
tuning voltage output is disabled (Vtune = 33 V in
application; see Fig.12), the test bits T2, T1 and T0 are set
to the normal mode and RSB is set to 1 (TSA5520) or 0
(TSA5521). When an 18-bit data word is transmitted, the
most significant bit of the divider N14 is internally set to 0
and bit RSA is set to 1. When a 19-bit data word is
transmitted, bit RSA is set to 0.

When a 27-bit word is transmitted, the frequency bits are

of the clock pulse and the control bits at the HIGH-to-LOW
transition of the chip enable line. In this mode, the
reference divider is given by the RSA and RSB bits (see
Table 7). The test bits T2, T1 and T0, the charge-pump
bit CP, the ratio select bit RSB and the OS bit can only be
selected or changed with a 27-bit transmission. They
remain programmed if an 18-bit or a 19-bit transmission

APPLICATION INFORMATION
Tuning amplifier
Crystal oscillator
The crystal oscillator uses a 4 MHz crystal connected in
series with an 18 pF capacitor thereby operating in the
series resonance mode. Connecting the oscillator to the
supply voltage is preferred but it can, however, also be
connected to ground.
The tuning amplifier is capable of driving the varicap
voltage without an external transistor. The tuning voltage
output must be connected to an external load of 27 kΩ
which is connected to the tuning voltage supply rail.
Figures 11 and 12 show a possible loop filter.
The component values depend on the oscillator
characteristics and the selected reference frequency.
Examples of I2C-bus sequences (SW = LOW)
Tables 8 to 12 show the various sequences where fosc = 100 MHz, BS4 = ON, ICP = 280 µA, N = 512, fxtal = 4 MHz,
S = START, A = acknowledge and P = STOP. The sequence is as follows:
START + address byte + divider byte 1 + divider byte 2 + control byte + band switch byte + STOP.
For the complete sequence see Table 8 (sequence 1) or Table 9 (sequence 2).

SOLDERING SO or SSOP
Introduction
SSOP
Wave soldering is not recommended for SSOP 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.
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
cases reflow soldering is often used.
If wave soldering cannot be avoided, the following
conditions must be observed:
• A double-wave (a turbulent wave with high upward
pressure followed by a smooth laminar wave)
soldering technique should be used.
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).
• The longitudinal axis of the package footprint must
be parallel to the solder flow and must incorporate
solder thieves at the downstream end.
Reflow soldering
Even with these conditions, only consider wave
soldering SSOP packages that have a body width of
4.4 mm, that is SSOP16 (SOT369-1) or
SSOP20 (SOT266-1).
Reflow soldering techniques are suitable for all SO and
SSOP packages.
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.
METHOD (SO OR SSOP)
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.
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.
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
Preheating is necessary to dry the paste and evaporate
the binding agent. Preheating duration: 45 minutes at
45 °C.
6 seconds. 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.
Wave soldering
SO
Repairing soldered joints
Wave soldering techniques can be used for all SO
packages if the following conditions are observed:
Fix the component by first soldering two diagonally-
opposite 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 at 270 to 320 °C.
• A double-wave (a turbulent wave with high upward
pressure followed by a smooth laminar wave) soldering
technique should be used.
• The longitudinal axis of the package footprint must be
parallel to the solder flow.
• The package footprint must incorporate solder thieves at
the downstream end.
