ICs for TV-SETS
ILA8362
1
INTEGRAL
Integrated PAL and PAL/NTSC TV Processor
GENERAL DESCRIPTION
The ILA8362A are single-chip TV processor which contain nearly all small signal functions that are required for a colour
television receiver. For a complete receiver the following circuits need to be added: a base-band delay line (ILA4661), a tuner
and output stages for audio, video and horizontal and vertical deflection and SECAM decoder ILA8395.
FEATURES
Multistandard vision IF circuit (positive and negative modulation)
Multistandard FM sound demodulator (4.5 MHz to 6.5 MHz)
Source selection for external A/V inputs (separate Y/C signals can also be applied)
Integrated chrominance trap and bandpass filters (automatically calibrated)
Integrated luminance delay line
PAL/NTSC colour decoder with automatic search system
Easy interfacing with the ILA8395 (SECAM decoder) for multistandard applications
RGB control circuit with linear RGB inputs and fast blanking
Input for automatic cut-off control with compensation for leakage current of the picture tube
Horizontal synchronisation with two control loops and alignment-free horizontal oscillator without external components
Vertical count-down circuit (50/60 Hz) and vertical preamplifier
Low dissipation (600 mW)
Small amount of peripheral components compared with competition ICs
Only one adjustment (vision IF demodulator)
The supply voltage for the ICs is 8 V. They are mounted in a shrink DIL envelope with 52 pins and are pin compatible.
