ILA8890, ILA8891
TV-processor with radio channel, keys and decoder
functions for LCD TV applications
General description
The ILA8890/91 are front-end TV-processors, which are provide
ƒ Audio & video IF signal processing
ƒ Line and frame synchronization signals forming
ƒ Audio/video input/output switching.
ƒ Chroma & luminance signals forming
ƒ Multi standard color decoding PAL, NTSC, SECAM (only for ILA8891).
ƒ One line duration delay of chroma signal (only for ILA8891)
ƒ YPRPB signals forming for PIP function processing. (only for ILA8891)
Main features:
- supply voltage 4,7 … 5,3 V (nominal value 5,0 V);
- audio part supply voltage 5; 8 V;
- consumption current 85 mA;
- total power dissipation 540 mW;
- output demodulated video signal swing
The ILA8890/91 are performed in 80-pin plastic package MO-112 CB-2
