LC7365

The LC7365 is designed as one kind of picture-in-picture (PIP) system controller ICs for use in NTSC, PAL or multi-system (both NTSC and PAL) TVs and VCRs. This device requires discrete LC7480 A/D converter and memory ICs. And this device 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 of the LC7365 are:(1)low voltage CMOS process for direct operation from telephone line;(2)uses TV crystal stadard to derive all frequencies;(3)wide operating voltage range: 2.5 to 10.0 V;(4)on-chip generation of a reference voltage to assure amplitude stability of the dual tones over the operating voltage and temperature range;(5)still and active video display control;(6)white and colored screen frames;(7)fixed and variable screen positioning;(8)gradual sub-screen display and erasure (wipe) function;(9)A/D interface, vertical (VERT) filter, memory controller.

The absolute maximum ratings of the LC7365 can be summarized as:(1)supply voltage range: -0.3 to 7.0 V;(2)input voltage range: -0.3 to VDD+0.3 V;(3)output voltage range: -0.3 to VDD+0.3 V;(4)allowable power dissipation: 500 mW;(5)operating temperature range: -10 to +70 ;(6)storage temperature range: -55 to +125 .
