Chrominance Processing
A quadrature demodulator extracts U and V components from the composite signal. The U/V signals then pass
through the gain control stage for chroma saturation adjustment. A comb filter is applied to both U and V to eliminate
cross-chrominance noise. Hue control is achieved with phase shift of the digitally controlled oscillator. An automatic
color killer (ACK) circuit is also included in this block. The ACK will suppress the chroma processing when the color
burst of the video signal is weak or not present.
2.2.6
Clock Circuits
An internal line-locked PLL generates the system and pixel clocks. Figure 2–19 shows a simplified clock circuit
diagram. The digital control oscillator (DCO) generates the reference signal for the horizontal PLL. A 14.318 MHz
clock is required to drive the DCO. This may be input to the TVP5040 at TTL level on the XTAL1 terminal, or a crystal
of 14.318 MHz fundamental resonant frequency may be connected across terminals XTAL1 and XTAL2. Figure 2–20
shows the reference clock configurations. For the example crystal circuit shown in Figure 2–20 (a parallel-resonant
crystal with 14.31818 MHz fundamental frequency), the external capacitors should have the following relationship:
CL1 = CL2 = 2CL – Cstray
Where Cstray is the terminal capacitance with respect to ground.
