The purpose of the 2-bit VCO range control is to improve the noise performance of the TVP7002. The frequency
ranges for the VCO are shown in Table 4. The phase of the ADC sample clock generated by the horizontal PLL
can be accurately controlled in 32 uniform steps over a single clock period (360/32 = 11.25 degrees phase
resolution) using the phase select register located at subaddress 04h.
The horizontal PLL characteristics are determined by the loop filter design, the PLL charge pump current, and the
VCO range setting. The loop filter design is shown in Figure 4. Supported settings of VCO range and charge
pump current for VESA standard display modes are listed in Table 4.
Figure 4. Horizontal PLL Loop Filter
In addition to sourcing the ADC sample clock from the horizontal PLL, an external pixel clock can be used (from
pin 80).
