Color Transient Improvement
Color transient improvement (CTI) enhances horizontal color transients. The color difference signal transition
points are maintained, but the edges are enhanced for signals which have bandwidth-limited color
components.

Clock Circuits
An internal line-locked PLL generates the system and pixel clocks. A 14.318-MHz clock is required to drive
the PLL. This can be input to the TVP5147 decoder at the 1.8-V level on terminal 74 (XTAL1), or a crystal of
14.318-MHz fundamental resonant frequency can be connected across terminals 74 and 75 (XTAL2). If a
parallel resonant circuit is used as shown in Figure 216, then the external capacitors must have the following
relationship:
CL1 = CL2 = 2CL CSTRAY,
where CSTRAY is the terminal capacitance with respect to ground. Figure 216 shows the reference clock
configurations. The TVP5147 decoder generates the DATACLK signal used for clocking data.
