FUNCTIONAL DESCRIPTION
CVBS or Y/C input

The TDA8315T has a video input which can be switched
to CVBS (with internal chrominance bandpass and trap
filters) and to Y/C (without chrominance bandpass and
trap filters). The switching between CVBS and Y/C is
achieved by the DC level of the CHROMA input (pin 15).

Integrated video filters

The circuit contains a chrominance bandpass and trap
circuit. The filters are realised by gyrator circuits that are
automatically tuned by comparing the tuning frequency
with the crystal frequency of the decoder. The
chrominance trap can be switched off by the DC level of
the CHROMA input.

The luminance delay line is also realised by gyrator
circuits.

Colour decoder

The colour decoder contains an alignment-free crystal
oscillator, a colour killer circuit and colour difference
demodulators. The gain of the two colour difference signal
demodulators is identical and the phase angle of the
reference carrier signals is 90°. This phase shift is
achieved internally. It is possible to switch the demodulator
angle to 110° by an internal matrix circuit. The switching is
obtained externally via pin 8.

TDA8315T

Synchronization circuit

The sync separator is preceded by a voltage controlled
amplifier which adjusts the sync pulse amplitude to a fixed
level. The sync pulses are then fed to the slicing stage
(separator) which operates at 50% of the amplitude.

The separated sync pulses are fed to the first phase
detector and to the coincidence detector. The coincidence
detector is used to detect whether the line oscillator is
synchronized. The PLL has a very high static steepness,
this ensures that the phase of the picture is independent of
the line frequency. The line oscillator operates at twice the
line frequency.

The oscillator network is internal. Because of the spread of
internal components an automatic adjustment circuit has
been added to the IC.
The circuit compares the oscillator frequency with that of
the crystal oscillator in the colour decoder. This results in
a free-running frequency which deviates less than 2% from
the typical value.

The horizontal output pulse is derived from the horizontal
oscillator via a pulse shaper. The pulse width of the output
pulse is 5.4 µs, the front edge of this pulse coincides with
the front edge of the sync pulse at the input.

The vertical output pulse is generated by a count-down
circuit. The pulse width is approximately 380 µs. Both the
horizontal and vertical pulses will always be available at
the outputs even when no input signal is available.

Notes to the characteristics

1. Signal with negative-going sync. Amplitude includes sync pulse amplitude.

2. This parameter is not tested during production and is guaranteed by the design and qualified by matrix batches which
are made in the pilot production period.

3. Burst amplitude; for a colour bar with 75% saturation the chrominance signal amplitude is 660 mV (p-p).

4. This parameter is not tested during production and is just given as application information for the designer of the
television receiver.

5. The signal-to-noise ratio is specified as a peak-to-peak signal with respect to RMS noise (bandwidth 5 MHz).

6. At a chrominance input voltage of 660 mV (p-p) (colour bar with 75% saturation i.e. burst signal amplitude
300 mV (p-p)) the dynamic range of the ACC is +6 and −18 dB.

7. All frequency variations are referenced to 3.58 MHz carrier frequency.
All oscillator specifications are measured with the Philips crystal series 9922 520.
If the spurious response of the crystal is lower than −3 dB with respect to the fundamental frequency for a damping
resistance of 1.5 kΩ, oscillation at the fundamental frequency is guaranteed.

The catching and detuning range are measured for nominal crystal parameters. These are:
a) load resonance frequency f0 (CL = 20 pF) = 3.579545 MHz
b) motional capacitance CM = 14.5 fF
c) parallel capacitance C0 = 4.5 pF.
The actual load capacitance in the application should be CL = 18 pF to account for parasitic capacitances on

and off chip.
The free-running frequency of the oscillator can be checked by pulling the saturation control pin to the positive supply
rail. In that condition the colour killer is not active so that the frequency offset is visible on the screen.

8. This value indicates the bandwidth of the complete chrominance circuit including the chrominance bandpass filter.
The bandwidth of the demodulator low-pass filter is approximately 1 MHz.

9. Output signal amplitude for a standard colour bar signal with 75% saturation and a demodulation angle of 90°. For a
demodulation angle of 110° the −V signal amplitude will decrease to 1.2 V (p-p) and the−U signal amplitude remains
unchanged. The nominal saturation is specified as maximum −6 dB.

10. Slicing level independent of sync pulse amplitude. The slicing level of the vertical sync separator is 70% (slicing level
in direction of black level) during strong signal reception (no noise detected in the incoming signal) and 30% during
weak signal reception.

11. The horizontal and vertical sync are stable while processing Copy Guard signals and signals with phase shifted sync
pulses (stretched tapes). Trick mode conditions of the VCR will also not disturb the synchronization. The value given
is the delay caused by the vertical sync pulse integrator. The integrator has been designed such that the vertical sync
is not disturbed for special anti-copy tapes with vertical sync pulses with an on/off time of 10/22 µs.

12. To obtain a good performance for both weak signal and VCR playback the time constant of the first control loop is
switched depending on the input signal condition. Therefore the circuit contains a noise detector and the time
constant is switched to ‘slow’ when excessive noise is present in the signal. In the ‘fast’ mode during the vertical
retrace time the phase detector current is increased 50% so that phase errors due to head-switching of the VCR are
corrected as soon as possible.

To prevent the horizontal synchronization being disturbed by anti-copy guard signals such as Macrovision the phase
detector is gated during the vertical retrace period so that pulses during scan have no effect on the output voltage.
The width of the gate pulse is approximately 12 µs. during weak signal conditions (noise detector active) the gating
is active during the complete scan period and the width of the gate pulse is reduced to 5.7 µs so that the effect of the
noise is reduced to a minimum.

The output current of the phase detector in the two modes is shown in Table 1.

Philips Semiconductors Preliminary specification

and sync processor

13. The horizontal output pulses are obtained from the horizontal oscillator by a pulse shaper. The width of the output
pulse is approximately 5.4 µs and the rising edge of the pulse symmetrically coincides with the start of the sync pulse
at the input.

14. The vertical output pulses are generated by a divider circuit. The vertical output pulse has a delay of 37.5 µs with
respect to the start of the vertical sync pulse at the input. This is caused by the clock frequency of the divider being
twice the horizontal frequency.

This divider circuit has 2 modes of operation:
Search mode (large window).
This mode is switched on when the circuit is not synchronized or, when a non-standard signal is received (the number

of lines per frame outside the range is between 261 and 264). In the search mode the divider can be triggered
between line 244 and line 288 (approximately 54 to 64.5 Hz).

Standard mode (narrow window).
This mode is switched on when more than 15 successive vertical sync pulses are detected in the narrow window.

When the circuit is in the standard mode and a vertical sync pulse is missing the output pulse is generated at the end
of the window. Consequently, the disturbance of the picture is very small. The circuit will switch back to the search
window when, for 6 successive vertical periods, no sync pulses are found within the window. When no input signal
is available the divider generates output pulses with a timing of 262.5 lines (standard 60 Hz signal).

SOLDERING
Plastic small-outline packages

YWAVE

B
During placement and before soldering, the component

must be fixed with a droplet of adhesive. After curing the
adhesive, the component can be soldered. The adhesive
can be applied by screen printing, pin transfer or syringe
dispensing.

Maximum permissible solder temperature is 260 °C, and
maximum duration of package immersion in solder bath is
10 s, if allowed to cool to less than 150 °C within 6 s.
Typical dwell time is 4 s at 250 °C.

A modified wave soldering technique is recommended
using two solder waves (dual-wave), in which a turbulent
wave with high upward pressure is followed by a smooth
laminar wave. Using a mildly-activated flux eliminates the
need for removal of corrosive residues in most
applications.

IRON OR PULSE

Fix the component by first soldering two, diagonally
opposite, end pins. Apply the heating tool to the flat part of
the pin only. Contact time must be limited to 10 s at up to
300 °C. When using proper tools, all other pins can be
soldered in one operation within 2 to 5 s at between 270
and 320 °C. (Pulse-heated soldering is not recommended
for SO packages.)

For pulse-heated solder tool (resistance) soldering of VSO
packages, solder is applied to the substrate by dipping or
by an extra thick tin/lead plating before package
placement.

-HEATED SOLDER TOOL)

Y SOLDER PASTE REFLOW

B
Reflow soldering requires the solder paste (a suspension

of fine solder particles, flux and binding agent) to be
applied to the substrate by screen printing, stencilling or
pressure-syringe dispensing before device placement.

Several techniques exist for reflowing; for example,
thermal conduction by heated belt, infrared, and
vapour-phase reflow. Dwell times vary between 50 and
300 s according to 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 min at 45 °C.
