FEATURES
Available in all ICs:
· Vision IF amplifier with high sensitivity and good figures
for differential phase and gain
· PLL demodulator for the IF signal
· Alignment-free sound demodulator
· Flexible source selection with a CVBS input for the
internal signal and Y/C or CVBS input for the external
signal
· Audio switch
· The output signal of the CVBS (Y/C) switch is externally
available

(auto-calibrated)
· Luminance delay line integrated
· A symmetrical peaking circuit in the luminance channel
· Black stretching of non-standard CVBS or luminance
signals
· RGB control circuit with black current stabilization and
white point adjustment
· Linear RGB inputs and fast blanking
· Horizontal synchronization with two control loops and
alignment-free horizontal oscillator
· Slow start and slow stop of the horizontal drive pulses
· Vertical count-down circuit

GENERAL DESCRIPTION
The various versions of the TDA837x series are I2C-bus
controlled single-chip TV processors which are intended to
be applied in PAL/NTSC (TDA8374 and TDA8375) and
NTSC (TDA8373 and TDA8377) television receivers.
All ICs are available in an SDIP56 package and some
versions are also available in a QFP64 package. The ICs
are pin compatible so that with one application board
NTSC and PAL/NTSC (or multistandard together with the
SECAM decoder TDA8395) receivers can be built.
Functionally this IC series is split in to 2 categories:
· Versions intended to be used in economy TV receivers
with all basic functions
· Versions with additional functions such as E-W
geometry control, horizontal and vertical zoom function
and YUV interface which are intended for TV receivers
with 110° picture tubes.
The various type numbers are given in Table 1.
The detailed differences between the various ICs are
given in Table 2.
