Description
Input R, G, and B video signals.
Video signal output pins. Output sampled and held video signals during
horizontal period.
Start pulse I/O pins of sample hold timing. STHR serves as an input
pin and STHL, as an output pin, in the case of right shift. In the case of
left shift, STHL serves as an input pin, and STHR, as an output pin.
A start pulse is read at the rising edge of CLI1. Sampling pulse SHPn
is generated at the rising edge of CLI1 through CLI3 during successive
sampling, and at the rising edge of CLI1 during simultaneous sampling
(for details, refer to the Timing charts in 5. FUNCTIONAL
DESCRIPTION).
Selects a multiplexer and one of the two sample and hold circuits at the
falling edge.
Resets the select counter of the multiplexer and the selector circuit of
the two sample and hold circuits when it goes high. After reset, the
multiplexer is turned OFF, so sure to input one pulse of the INH signal
before inputting the video signal. If the video signal is input without the
INH signal, sampling is not executed.
Four types of color filter arrays can be supported by combination of
MP/TH and MP/1.5.
