Product specification
YC 8-bit low-power analog-to-digital video
interface
TDA8758
FUNCTIONAL DESCRIPTION
The TDA8758 provides a simple interface between CVBS
or Y/C analog signals and a digital colour decoder.
Video inputs selection
The input selector allows a choice from different video
sources, and has one of the following configurations:
A: Two Y/C and one CVBS signals
B: One Y/C and two CVBS signals
C: Three CVBS signals (only the Y channel is used).
The wiring of the five video inputs (pins 2, 4, 6, 9 and 11)
and the control of the two selection inputs (pins 5 and 12)
will depend on the available video sources.
• In configuration A, connect as follows:
– Y1 to pin 11
– C1 to pin 4
– Y2 to pin 9
– C2 to pin 2
– CVBS3 to pin 6.
Keep SEL2 (pin 5) LOW and select Y1/C1 or Y2/C2 by
switching SEL1 (pin 12).
CVBS3 is selected with SEL1 and SEL2 HIGH.
• In configuration B, replace Y1 (or Y2) by a CVBS input
(no more C1 or C2). The selection mode is the same.
• In configuration C, connect as follows:
– CVBS1 to pin 11
– CVBS2 to pin 9
– CVBS3 to pin 6.
Use both SEL1 and SEL2 to select inputs.
Remark: the video inputs selection is a static selection.
Synchronization pulses
GATE A and GATE B pulses are synchronization pulses
occurring during the sync period and rear porch
respectively. They should be distinct.
On the Y channel, the digital output of the ADC is
compared to internal digital reference levels. The resultant
outputs control the charge or discharge current of a
capacitor connected to the CAGC pin. The voltage across
this capacitor controls the gain of the video amplifier.
This is the control loop.
The sync level comparator is active during a positive-going
pulse at the GATE A input. This means that sync pulse of
the composite video signal is used as an amplitude
reference. The bottom of the sync pulse is adjusted to
obtain a digital output of logic 1 at the converter Y output.
As the black level is digital level 64, the sync pulse will
have a digital amplitude of 64 LSBs.
The Peak White control loop is active when the selection
pin PWE is LOW. Then, if the Y video signal exceeds the
digital code of 255, it will be limited to avoid any over-range
of the converter.
The clamp level control is accomplished by using the same
techniques as used for the gain control. On both Y and C
channels, the black level digital comparators are active
during a positive-going pulse at the GATE B input. On the
Y channel, the clamping capacitor connected to the CCLPY
pin will be charged or discharged to adjust the digital
output to code 64. On the C channel, the clamping
capacitor connected to the CCLPC pin will be charged or
discharged to adjust the digital output to code 128.
