LC74411NE

Ordering number : EN*5519A CMOS LSI 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. Package Dimensions unit: mm 3071-DIP64S [LC74411N] 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% LC...
