LC74411N, LC74411NE
PIP Controller
Preliminary
Overview
The LC74411N and LC74411NE are digital processing
controllers for PIP (picture-in-picture) systems in TV sets
and VCRs. These ICs incorporate three circuits, a
multiplexed A/D converter, field memory, and a D/A
converter, to implement the PIP digital processing block in
a single chip.

Features
• Horizontal resolution: 450 pixels*
• Single-chip implementation of the three circuits required
in a PIP digital processing block: A/D converter, field
memory, and D/A converter circuits
• High image quality provided by vertical filtering
• I²C bus adopted
• Built-in PLL circuit (requires an external low-pass filter)
• Supports NTSC and PAL, TV and VCR applications,
and multi-format (NTSC and PAL) applications.
• External control function
• 8-bit D/A converter (PWM type): 6 pins
• General-purpose ports: 8 pins
• Sub-screen specifications
• Display on/off, frame/no frame, frame color switching,
wipe function
• Display position - Specifiable as an 8-bit value for each
of the horizontal and vertical directions.
• Size
Vertical reduction: 1/3, 1/4
Horizontal reduction: 1/3, 1/4
– The horizontal size can be adjusted by adjusting the
PLL divisor
– The display area vertical and horizontal positions
can be varied independently.
• Horizontal resolution (Y signal): about 190 dots
• Quantization: 6 bits
• Operating supply voltage LC74411NE : 5 V ±5%
LC74411N : 5 V ±10%
