Figure 41. Recommended Analog Circuit Layout
T he circuit below can be used to generate a 13.5 MHz waveform using the 27 MHz clock and the
HSYNC
pulse. T his waveform is
guaranteed to produce the 13.5 MHz clock in synchronization with the 27 MHz clock. T his 13.5 MHz clock can be used if
13.5 MHz clock is required by the MPEG decoder. T his will guarantee that the Cr and Cb pixel information is input to the
ADV7175/ADV7176 in the correct sequence.
