I2C Control
Data format
Data 1 is stored at register address A1. Data 2 is stored at register address A1 + 1, i.e., the address given by incrementing
A1. If the address exceeds 11H, it wraps to 00H.

Synchronizing Signal Input
Sync separation
The LC74411N and LC74411NE require sync separated (including AFC processing) V and H signals for both the main
and sub-screen. Since V is used for field discrimination and H is used as the PLL reference signal, these signals must be
provided reliably.
– The H-M and H-S pin inputs are assumed to be delayed about 1 s from the video signal’s horizontal synchronizing
signal and set to standard values.
– Equalizing pulses must be excluded.
– Since noise on the synchronizing signal will disrupt the display, these lines should be placed carefully.
– If the synchronizing signal is unstable, the sub-screen display may be disrupted. We recommend turning off sub-
screen display in such cases.
Field discrimination circuit
Since the circuit discriminates based on the phase difference between the falling edges of the H and L signals, these
signals must be provided with the timing shown in the figure below.
