SLES213 – MAY 2008
Terminals 8 (RESETB) and 28 (PDN) work together to put the TVP5150AM1 decoder into one of the two
modes. Table 3-8 shows the configuration.
After power-up, the device is in an unknown state with its outputs undefined, until it receives a RESETB
active low for at least 500 ns. The power supplies must be active and stable for 20 ms before RESETB
becomes inactive.

Normal operation
The TVP5150AM1 decoder is initialized and controlled by a set of internal registers that set all device
operating parameters. Communication between the external controller and the TVP5150AM1 decoder is
through I2C. Table 3-9 shows the summary of these registers. The reserved registers must not be written.
Reserved bits in the defined registers must be written with zeros, unless otherwise noted. The detailed
programming information of each register is described in the following sections.
