Product specication
I2C-bus autosync deection controllers for
PC/TV monitors
TDA4853; TDA4854
FEATURES
Concept features
Full horizontal plus vertical autosync capability; TV and
VCR mode included
Extended horizontal frequency range from
15 to 130 kHz
Comprehensive set of I2C-bus driven geometry
adjustments and functions, including standby mode
Very good vertical linearity
Moire cancellation
Start-up and switch-off sequence for safe operation of
all power components
X-ray protection
Flexible switched mode B+ supply function block for
feedback and feed forward converter
Internally stabilized voltage reference
Drive signal for focus amplifiers with combined
horizontal and vertical parabola waveforms (TDA4854)
DC controllable inputs for Extremely High Tension
(EHT) compensation
SDIP32 package.
Synchronization
Can handle all sync signals (horizontal, vertical,
composite and sync-on-video)
Output for video clamping (leading/trailing edge
selectable by I2C-bus), vertical blanking and protection
blanking
Output for fast unlock status of horizontal
synchronization and blanking on grid 1 of picture tube.
Horizontal section
I2C-bus controllable wide range linear picture position,
pin unbalance and parallelogram correction via
horizontal phase
Frequency-locked loop for smooth catching of horizontal
frequency
TV mode at 15.625 or 15.750 kHz selectable by I2C-bus
Simple frequency preset of fmin and fmax by external
resistors
Low jitter
Soft start for horizontal and B+ control drive signals.
Vertical section
I2C-bus controllable vertical picture size, picture
position, linearity (S-correction) and linearity balance
Output for I2C-bus controllable vertical sawtooth and
parabola (for pin unbalance and parallelogram)
Vertical picture size independent of frequency
Differential current outputs for DC coupling to vertical
booster
50 to 160 Hz vertical autosync range.
East-West (EW) section
I2C-bus controllable output for horizontal pincushion,
horizontal size, corner and trapezium correction
Optional tracking of EW drive waveform with line
frequency selectable by I2C-bus.
Focus section of TDA4854
I2C-bus controllable output for horizontal and vertical
parabolas
Vertical parabola is independent of frequency and tracks
with vertical adjustments
Horizontal parabola independent of frequency
Pre-correction of delay in focus output stage.
