Clock Circuits
An internal line-locked PLL generates the system and pixel clocks. A 14.31818-MHz clock is required to
drive the PLL. This may be input to the TVP5154A decoder on terminal 124 (XIN), or a crystal of
14.31818-MHz fundamental resonant frequency may be connected across terminals 123 and 124 (XIN
and XOUT). Figure 5-1 shows the reference clock configurations. For the example crystal circuit shown (a
parallel-resonant crystal with 14.31818-MHz fundamental frequency), the external capacitors must have
the following relationship:
CL1 = CL2 = 2CL – CSTRAY
where CSTRAY is the terminal capacitance with respect to ground and CL is the crystal load capacitance
specified by the crystal manufacturer. Figure 5-1 shows the reference clock configurations.
NOTE: The resistor (R) in parallel with the crystal is recommended to support a wide range of crystal types. A 100-k
Ω resistor
may be used for most crystal types.
