7442 Product details

Overview
The LC7442 and LC7442E are memory controller for PIP (picture-in-picture) systems for TV sets and VCRs. Since this IC includes 3 built-in D/A converter circuits on chip, a component-type PIP system can be constructed by combining this product with memory and an A/D converter such as the LC7480.

Features
• Horizontal resolution: 600 TV lines*1
• Three built-in D/A converter provided on-chip in the PIP memory controller block
• High image quality display provided by vertical filter function frame display*2
• Built-in even/odd field determination circuit
• Built-in PLL circuit (requires external LPF)
• Handles NTSC/PAL, TV/VCR, and multi-mode systems (NTSC-PAL)*3
• Sub-screen specifications
   — Display modes: 2-screen, 3-screen, and 4-screen*2
   — Display on/off and frame on/off/color switching, wipe function
   — Supports switching between fixed (4 corners) and arbitrary (8-bit specification of vertical and horizontal position) display positions
   — The size of the display area can be either variable or 1/9 of the main picture area, i.e 1/3 of the vertical and 1/3 of the horizontal dimensions of the screen
   — Horizontal resolution of about 250 dots (Y signal)
   — Gradations (quantization): 64 (6 bits)
• Operating power supply voltage: 5 V ±10%
• Package: QIP64E, DIP64S
