Tentative Device Specification
TDA884X/5X-N2 series
FEATURES
The following features are available in all IC’s:
Multi-standard vision IF circuit with an alignment-free
PLL demodulator without external components
Alignment-free multi-standard FM sound demodulator
(4.5 MHz to 6.5 MHz)
Audio switch
Flexible source selection with CVBS switch and
Y(CVBS)/C input so that a comb filter can be applied
Integrated chrominance trap circuit
Integrated luminance delay line
Asymmetrical peaking in the luminance channel with a
(defeatable) noise coring function
Black stretching of non-standard CVBS or luminance
signals
Integrated chroma band-pass filter with switchable
centre frequency
Dynamic skin tone control circuit
Blue stretch circuit which offsets colours near white
towards blue
RGB control circuit with “Continuous Cathode
Calibration” and white point adjustment
Possibility to insert a “blue back” option when no video
signal is available
Horizontal synchronization with two control loops and
alignment-free horizontal oscillator
Vertical count-down circuit
Vertical driver optimised for DC-coupled vertical output
stages
I2C-bus control of various functions
The detailed differences between the various IC’s are
given in the table on page 3.
GENERAL DESCRIPTION
The various versions of the TDA 884X/5X series are
I2C-bus controlled single chip TV processors which are
intended to be applied in PAL, NTSC, PAL/NTSC and
multi-standard television receivers. The N2 version is pin
and application compatible with the N1 version, however,
a new feature has been added which makes the N2 more
attractive. The IF PLL demodulator has been replaced by
an alignment-free IF PLL demodulator with internal VCO
(no tuned circuit required). The setting of the various
frequencies (33.4, 33.9, 38, 38.9, 45,75 and 58.75 MHz)
can be made via the I2C-bus.
Because of this difference the N2 version is compatible
with the N1, however, N1 devices cannot be used in an
optimised N2 application.
Functionally the IC series is split up is 3 categories, viz:
Versions intended to be used in economy TV receivers
with all basic functions (envelope: S-DIP 56 and QFP
64)
Versions with additional features like E-W geometry
control, H-V zoom function and YUV interface which are
intended for TV receivers with 110° picture tubes
(envelope: S-DIP 56)
Versions which have in addition a second RGB input
with saturation control and a second CVBS output
(envelope: QFP 64)
The various type numbers are given in the table below.
