Preliminary
Overview
The LC7441N, 7441NE are picture-in picture (PIP) system controller ICs for use in NTSC, PAL or multi-system
(both NTSC and PAL) TVs and VCRs. The LC7441 PIP
system configuration requires discrete LC7480 A/D converter and memory ICs.
The LC7441 system controller IC provides nested-picture
main-screen/sub-screen video signal control. Single or multiple (2) sub-screens occupying 11.11% (one-third height,
one-third width) of the main-screen can be constructed and
controlled. Features include still/active display, white/color
frame, fixed/variable (screen) positioning, and wipe function for gradual sub-screen display and erasure. Sub-screen
horizontal resolution is achieved by 248 6-bit, 64-level
samples.
The LC7441 construction includes A/D interface,
vertical(VERT) filter, memory controller, odd-field decision circuits, read/write PLLs and D/A converters.
The LC7441 operates from a 5 V supply and is a v ailable in
64-pin DIPs and 64-pin QIPs.
