DESCRIPTION

The TSA5512 is a single chip PLL frequency synthesizer
designed for TV tuning systems. Control data is entered
via the I2C-bus; five serial bytes are required to address
the device, select the oscillator frequency, programme the
eight output ports and set the charge-pump current. Four
of these ports can also be used as input ports (three
general purpose I/O ports, one ADC). Digital information
concerning those ports can be read out of the TSA5512 on
the SDA line (one status byte) during a READ operation. A
flag is set when the loop is “in-lock” and is read during a
READ operation. The device has one fixed I2C-bus
address and 3 programmable addresses, programmed by
applying a specific voltage on Port 3. The phase
comparator operates at 7.8125 kHz when a 4 MHz crystal
is used.

PINNING

FUNCTIONAL DESCRIPTION

The TSA5512 is controlled via the two-wire I

2

C-bus. For programming, there is one module address (7 bits) and the R/W

bit for selecting READ or WRITE mode.

WRITE mode: R/W = 0 (see Table 1)

After the address transmission (first byte), data bytes can be sent to the device. Four data bytes are required to fully
program the TSA5512. The bus transceiver has an auto-increment facility which permits the programming of the
TSA5512 within one single transmission (address + 4 data bytes).

The TSA5512 can also be partially programmed on the condition that the first data byte following the address is byte 2
or byte 4. The meaning of the bits in the data bytes is given in Table 1. The first bit of the first data byte transmitted
indicates whether frequency data (first bit = 0) or charge pump and port information (first bit = 1) will follow. Until an
I2C-bus STOP condition is sent by the controller, additional data bytes can be entered without the need to re-address the
device. This allows a smooth frequency sweep for fine tuning or AFC purpose. At power-on the ports are set to the high
impedance state.

The 7.8125 kHz reference frequency is obtained by dividing the output of the 4 MHz crystal oscillator by 512.
Because the input of UHF/VHF signal is first divided by 8 the step size is 62.5 kHz. A 3.2 MHz crystal can offer step sizes
of 50 kHz.

READ mode: R/W = 1 (see Table 2)

Data can be read out of the TSA5512 by setting the R/W bit to 1. After the slave address has been recognized, the
TSA5512 generates an acknowledge pulse and the first data byte (status word) is transferred on the SDA line (MSB first).
Data is valid on the SDA line during a high position of the SCL clock signal. A second data byte can be read out of the
TSA5512 if the processor generates an acknowledge on the SDA line. End of transmission will occur if no acknowledge
from the processor occurs. The TSA5512 will then release the data line to allow the processor to generate a STOP
condition. When ports P3 to P7 are used as inputs, they must be programmed in their high-impedance state. The POR
flag (power-on reset) is set to 1 when VCC goes below 3 V and at power-on. It is reset when an end of data is detected
by the TSA5512 (end of a READ sequence). Control of the loop is made possible with the in-lock flag FL which indicates
(FL = 1) when the loop is phase-locked. The bits I2, I1 and I0 represent the status of the I/O ports P7, P5 and P4
respectively. A logic 0 indicates a LOW level and a logic 1 a HIGH level (TTL levels). A built-in 5-level ADC is available
on I/O port P6. This converter can be used to feed AFC information to the controller from the IF section of the television
as illustrated in the typical application circuit (Fig.8). The relationship between bits A2, A1 and A0 and the input voltage
on port P6 is given in Table 3.

Table 2 Read data format

Note to Table 2

MSB is transmitted first

Address selection

The module address contains programmable address bits (MA1 and MA0) which together with the I/O port P3 offers the
possibility of having several synthesizers (up to 3) in one system.
The relationship between MA1 and MA0 and the input voltage I/O port P3 is given in Table 4

SOLDERING
Introduction

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.

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).

DIP

SOLDERING BY DIPPING OR BY WAVE
The maximum permissible temperature of the solder is

260 °C; solder at this temperature must not be in contact
with the joint for more than 5 seconds. The total contact
time of successive solder waves must not exceed
5 seconds.

The device may be mounted up to the seating plane, but
the temperature of the plastic body must not exceed the
specified maximum storage temperature (T

stg max

). If the
printed-circuit board has been pre-heated, forced cooling
may be necessary immediately after soldering to keep the
temperature within the permissible limit.

R

EPAIRING SOLDERED JOINTS

Apply a low voltage soldering iron (less than 24 V) to the
lead(s) of the package, below the seating plane or not
more than 2 mm above it. If the temperature of the
soldering iron bit is less than 300 °C it may remain in
contact for up to 10 seconds. If the bit temperature is
between 300 and 400 °C, contact may be up to 5 seconds.

SO and SSOP

REFLOW SOLDERING
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.

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.

Preheating is necessary to dry the paste and evaporate
the binding agent. Preheating duration: 45 minutes at
45 °C.

W

AVE SOLDERING

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.

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.

• The longitudinal axis of the package footprint must

be parallel to the solder flow and must incorporate
solder thieves at the downstream end.

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).

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.

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.

A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.

R

EPAIRING SOLDERED JOINTS

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.
