GENERAL DESCRIPTION
The TDA8764A is a 10-bit high-speed low-power
Analog-to-Digital Converter (ADC) for professional video
and other applications. It converts the analog input signal
into 10-bit binary or gray coded digital words at a maximum
sampling rate of 60 MHz. All digital inputs and outputs are
TTL and CMOS compatible, although a low-level sine
wave clock input signal is allowed.
The device requires an external source to drive its
reference ladder.

Notes
1. The rise and fall times of the clock signal must not be less than 0.5 ns.
2. The input admittance is
3. Analog input voltages producing code 0 up to and including code 1023:
a) V
offset(B)
(offset voltage BOTTOM) is the difference between the analog input which produces data equal to 00
and the reference voltage BOTTOM (V
RB
) at T
amb
= 25
C.
b) V
offset(T)
(offset voltage TOP) is the difference between V
RT
(reference voltage TOP) and the analog input which
produces data outputs equal to code 1023 at T
amb
= 25
C.
4. In order to ensure the optimum linearity performance of such converter architecture the lower and upper extremities
of the converter reference resistor ladder (corresponding to output codes 0 and 1023 respectively) are connected to
pins V
RB
and V
RT
via offset resistors R
OB
and R
OT
as shown in Fig.4.
a) The current flowing into the resistor ladder is
and the full-scale input range at the converter,
to cover code 0 to 1023, is
b) Since R
L
, R
OB
and R
OT
have similar behaviour with respect to process and temperature variation, the ratio
will be kept reasonably constant from device to device. Consequently variation of the output
codes at a given input voltage depends mainly on the difference V
RT
-
V
RB
and its variation with temperature and
supply voltage. When several ADCs are connected in parallel and fed with the same reference source, the
matching between each of them is then optimized.
5.
6. The analog bandwidth is defined as the maximum input sine wave frequency which can be applied to the device.
No glitches greater than 2 LSBs, nor any significant attenuation are observed in the reconstructed signal.

7. The analog input settling time is the minimum time required for the input signal to be stabilized after a sharp full-scale
input (square wave signal) in order to sample the signal and obtain correct output data.
8. Effective bits are obtained via a Fast Fourier Transform (FFT) treatment taking 8K acquisition points per equivalent
fundamental period. The calculation takes into account all harmonics and noise up to half of the clock frequency
(Nyquist frequency). Conversion to signal-to-noise ratio: S/N = EB
6.02 + 1.76 dB.
9. Intermodulation measured relative to either tone with analog input frequencies of 4.5 and 4.3 MHz. The two input
signals have the same amplitude and the total amplitude of both signals provides full-scale to the converter.
10. Output data acquisition: the output data is available after the maximum delay time of t
d
. It is recommended to have
the lowest possible output load. These parameters are guaranteed by characterization and not by production test.

SOLDERING
Introduction to soldering surface mount packages
This text gives a very brief insight to a complex technology.
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 is not always suitable
for surface mount ICs, or for printed-circuit boards with
high population densities. In these situations reflow
soldering is often used.
Reflow soldering
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 methods exist for reflowing; for example,
infrared/convection 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 230
C.
Wave soldering
Conventional single wave soldering is not recommended
for surface mount devices (SMDs) or printed-circuit boards
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.
For packages with leads on four sides, the footprint 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 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.
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.
Manual 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.

Suitability of surface mount IC packages for wave and reflow soldering methods
Notes
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
"Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods".
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 and TSSOP 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.
