5. IC6201 (RH-iXC068WJQZQ)

This is a main CPU. The output from the STB is 1080p. However, if the 480p and 1080i signals are directly connected to the display, this IC con-
verts the 480p and 1080i signals into 1080p signals.

Also, the OSD of the display is created here and added to the picture signals.

As the wall picture function, reading and processing operations of the data from the USB terminal are implemented here.

6. IC6301 (RH-iXB800WJQZY)

This is a clock generator, which generates 48MHz for SCC, 54MHz for STC and 74.25MHz for PWM from the crystal oscillator of 27MHz.

Distribution, DDR function enable.
The use of these multi-function depends on the setting of MODE<1:0>.
  MODE<1:0>=HH(Single-in/Single-out Mode)
     H: Distribution function enable.
     L: Distribution function disable.
  MODE<1:0>=HL(Single-in/Single-out Mode)
     H: DDR (Double Edge input) function enable.
     L: DDR (Double Edge input) function disable.
