I2C-bus autosync deection controllers for
PC/TV monitors
TDA4853; TDA4854
Start-up procedure
VCC < 8.3 V:
As long as the supply voltage is too low for correct
operation, the IC will give no acknowledge due to
internal Power-on reset (POR)
Supply current is 9 mA or less.
VCC > 8.3 V:
The internal POR has ended and the IC is in standby
mode
Control bits STDBY and SOFTST are reset to their start
values
All other register contents are random
Pin HUNLOCK is at HIGH-level.
Setting control bit STDBY = 0:
Enables internal power supply
Supply current increases from 9 to 70 mA
When VCC < 8.6 V register SOFTST cannot be set by
the I2C-bus
Output stages are disabled, except the vertical output
Pin HUNLOCK is at HIGH-level.
Setting all registers to defined values:
Due to the hardware configuration of the IC
(no auto-increment) any register setting needs a
complete 3-byte I2C-bus data transfer as follows:
START - IC address - subaddress - data - STOP.
Setting control bit SOFTST = 1:
Before starting the soft-start sequence a delay of
minimum 80 ms is necessary to obtain correct function
of the horizontal drive
HDRV duty cycle increases
BDRV duty cycle increases
PLL1 and PLL2 are enabled.
IC in full operation:
Pin HUNLOCK is at LOW-level when PLL1 is locked
Any change of the register content will result in
immediate change of the output behaviour
Setting control bit SOFTST = 0 is the only way (except
power-down via pin VCC) to leave the operating mode.
Soft-down sequence:
See L4 of Fig.21 for starting the soft-down sequence.
Fig.20 I2C-bus flow for start-up.
