This VCLK pin has dual functionality. It provides 27 Mhz when
Digital video output is used & as an input for PCM_CLK when
ext. I2S is used. Option jumpers are provided.
Exercise caution when connecting to this line; excessive
loading can cause noise and increase jitter levels & degrade
the quality of SPDIF and I2S signals.

Analog video performance
The video output standard follows the source material. The
OSD can be switched between PAL and NTSC.
The module has 6 analog video outputs in 4 format: CVBS, Y/
C, and RGB (YUV). However, depending on the module
configuration, not all output can be available at the same time.

Option Jumpers:
J1, J2 & J3 hard select the required video output on Connector
1800. Alternatively, pre-determined Software setting, via slash
option, is also possible. DAC's that are not in used should be
turned off.
Note: RGB and YUV component video signals shared the
same lines. Therefore, the module is not able to output both
RGB and YUV at the same time.
