Product specification
Video processor with automatic cut-off control
TDA4688
I2C-BUS PROTOCOL
Control
The I2C-bus transmitter provides the data bytes to select
and adjust the following functions and parameters:
• Brightness adjust
• Saturation adjust
• Contrast adjust
• DC output e.g. for hue control
• RGB gain adjust
• Peak drive limiting level adjust
• Selects either 3-level or 2-level (5 V) sandcastle pulse
• Enables cut-off control; enables output clamping
(2 different modes)
• Selects either PAL/SECAM or NTSC matrix
• Enables/disables synchronization of the execution of
I2C-bus commands with the vertical blanking interval
• Enables Y/CD, RGB1 or RGB2 input.
I2C-bus transmitter and data transfer
I2C-BUS SPECIFICATION
The I2C-bus is a bidirectional, two-wire, serial data bus for
intercommunication between ICs in an equipment.
The microcontroller transmits data to the I2C-bus receiver
in the TDA4688 over the serial data line SDA (pin 27)
synchronized by the serial clock line SCL (pin 28).
Both lines are normally connected to a positive voltage
supply through pull-up resistors. Data is transferred when
the SCL line is LOW. When SCL is HIGH the serial data
line SDA must be stable. A HIGH-to-LOW transition of the
SDA line when SCL is HIGH is defined as a START bit.
A LOW-to-HIGH transition of the SDA line when SCL is
HIGH is defined as a STOP bit.
Each transmission must start with a START bit and end
with a STOP bit. The bus is busy after a START bit and is
only free again after a STOP bit has been transmitted.
I2C-BUS RECEIVER (MICROCONTROLLER WRITE MODE)
Each transmission to the I2C-bus receiver consists of at
least three bytes following the START bit. Each byte is
acknowledged by an acknowledge bit immediately
following each byte. The first byte is the Module Address
(MAD) byte, also called slave address byte. This includes
the module address, 1000100 for the TDA4688.
The TDA4688 is a slave receiver (R/W = 0), therefore the
module address byte is 10001000 (88H; see also Fig.3).
The length of a data transmission is unrestricted, but the
module address and the correct subaddress must be
transmitted before the data byte(s). The order of data
transmission is shown in Figs 4 and 5.
Without auto-increment (BREN = 0 or 1) the module
address (MAD) byte is followed by a SubAddress (SAD)
byte and one data byte only (see Fig.4).
