3-2-5. Outline of internal function blocks

» AMP block
3-channel amplifier optimizes, for ADC input, RGB analog input signal connected to condenser and YCbCr
analog input signal. Analog input signal connected to condenser is given a sync clamp on its pedestal level by
the clamp pulse received externally (CLPIN pin (113)).
There are 2 lines in analog input signal. One is any of INPUT1 to 6 selected and excluding 480i/580I composite
signals, while another is DVI analog input signal.
In the RGB input mode, the clamp level for black level adjustment is adjusted by sub-brightness in 256 grades for
each of the 3 channels independently. In the component input mode, the adjustment is made using the median
point of ADC input dynamic range as its middle point.

» SYNC block
Horizontal sync signal used for PLL is any of the signals selected among SYNCIN1 pin (111), SYNCIN2 pin
(112) and G/YIN1 pin (124) after sync separation.
Input pin
SYNCIN1 External horizontal sync
SYNCIN2 Horizontal sync output (V0_HSYNR pin (406))
from IX3434CE (input section)
G/YIN1 Analog input (G/Y)
· The sync signal inputted to IX3434CE (input section) can be observed with SYNCIN2.
