  1. 2007/01/30 TDA8360 - Integrated PAL and PAL/NTSC TV processors
Available in TDA8360, TDA8361 and TDA8362
· Vision IF amplifier with high sensitivity and good differential gain and phase
· Multistandard FM sound demodulator (4.5 MHz to 6.5 MHz)
· Integrated chrominance trap and bandpass filters (automatically calibrated)
· Integrated luminance delay line
· RGB control circuit with linear RGB inputs and fast blanking
· Horizontal synchronization with two control loops and alignment-free horizontal oscillator without external components
· Vertical count-down circuit (50/60 Hz) and vertical preamplifier
· Low dissipation (700 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.

Additional features
· Alignment-free PAL colour decoder for all PAL standards, including PAL-N and PAL-M.
· PAL/NTSC colour decoder with automatic search system
· Source selection for external audio/video (A/V) inputs (separate Y/C signals can also be applied).
· Multistandard vision IF circuit (positive and negative modulation)
· PAL/NTSC colour decoder with automatic search system · Source selection for external A/V inputs (separate Y/C signals can also be applied)
· Easy interfacing with the TDA8395 (SECAM decoder) for multistandard applications.

The TDA8360, TDA8361 and TDA8362 are single-chip TV processors 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 (TDA4661), a tuner and output stages for audio, video and horizontal and vertical deflection. Because of the different functional contents of the ICs the set maker can make the optimum choice depending on the requirements for the receiver. The TDA8360 is intended for simple PAL receivers (all PAL standards, including PAL-N and PAL-M are possible). The TDA8361 contains a PAL/NTSC decoder and has an A/V switch. For real multistandard applications the TDA8362 is available. In addition to the extra functions which are available in the TDA8361, the TDA8362 can handle signals with positive modulation and it supplies the signals which are required for the SECAM decoder TDA8395.
