  • Page 6: Functional Description

    A 25-MHz clock is required to drive the PLL of the TVP9900. Some tuner devices have a 4-MHz clock output that can be used as the demodulator clock source. The TVP9900EVM has the option of using a 4-MHz clock input from the tuner as the clock source, or the default setting of using the onboard 25-MHz crystal.

  • Page 7: Board-Level Description

    Test Points and Jumpers The TVP9900EVM was designed with test points and jumpers to help in evaluation and troubleshooting. Each jumper is set by default to its preferred state for the TVP9900EVM. There are test points for I C SCL and SDA, GND, 5 V, 3.3 V, and 1.5 V.
