(DMUX Parallel Data out Mode)
The RGB analog input signal AC coupled is optimized by using a 3-ch AMP and the signal is input to the ADC.
The analog signal input to the ADC is sampled by using a clock generated by the PLL.
The identical signal with the sampling clock for analog input signal is output from the CLK (Pin 99). At each
clock cycle, sampled data is divided into pins in port A side and port B side.
The data output on the port A side possesses a 3-clock pipeline delay versus the sampling clock, while the
data output on the port B side possesses a 2-clock pipeline delay.
The output timing is the same for data output from both ports. Data is maintained for two cycles (2T) of the
sampling clock.
ADC data is output with a propagation delay (Td_7) ranges from 1.3ns (min.) to 2.2ns (max.) versus the clock
output from the 1/2XCLK (Pin 100).
An interface of the following type is possible when this IC is run in DMUX Parallel Data out Mode.
With the interface shown above, the post-stage scaling IC acquire data by using the clock signal output from
the 1/2CLK pin of the ADC.
In case of this interface, the setup time of the post-stage scaling IC is,
While the hold time is,
ts (min.) = T – 2.2ns
th (min.) = T + 1.3ns
