3 TUNER Either a PLL or a VST tuner is used as a tuner. UV1316 (VHF/UHF) is used as a PLL tuner. For only PALM/N, NTSC M applications UV 1336 is used as the PLL tuner. UV 1315 (VHF/UHF) is used as a VST Tuner.

It is supplied by +12VDC coming from a separate winding in the SMPS transformer. An output power of 3W (THD=10%) can be delivered into an 16 ohm load. 5 VERTICAL OUTPUT STAGE WITH TDA8174A 6 POWER SUPPLY (SMPS) The TDA8174A is a power amplifier circuit for use in 90° and 110° colour deflection systems for 25 to 200 Hz field frequencies, and for 4 : 3 and 16 : 9 picture tubes. The DC voltages required at various parts of the chassis are provided by an SMPS transformer controlled by the IC UC3842/ 3 which is designed for driving, controlling and protecting switching transistor of SMPS. The transformer produces 115V for FBT input, ±12V for audio output IC, S+5V and 8V for ST92195. 7 DISCRETE VIDEO AMPLIFIER Three high voltage, high frequency transistor is used for RGB amplifier. This application works on fixed AC and DC gains. 5 8 SERIAL ACCESS CMOS 8K EEPROM 24C08 The 24C08 is a 8Kbit electrically erasable programmable memory (EEPROM), organized as 4 blocks of 256*08 bits. The memory is compatible with the IІC standard, two wire serial interface which uses a bi-directional data bus and serial clock. 9 SAW FILTERS Saw filter type : G1975M : K2
