The sampling frequencies that control the number of pixels per line differ depending on the video format and
standards. Table 2–1 shows a summary of the sampling frequencies.

I2C Interface
The I2C standard consists of two signals, serial input/output data (SDA) line and input/output clock line
(SCL), that carry information between the devices connected to the bus. A third signal (I2CA) is used for
slave address selection. Although the I2C system can be multimastered, the TVP5010 will function as a
slave device only.
Both SDA and SCL are bidirectional lines that connect to a positive supply voltage via a pullup resistor. When
the bus is free, both lines are high.
The slave address (I2CA) should be tied high or low to distinguish between two TVP5010 devices commonly
on the I2C bus.
Table 2–3 summarizes the terminal functions of the I2C mode host interface.
