AN5491K

ICs for TV AN5491K Synchronous signal and deflection distortion correction processing IC supporting I2C bus for HD, wide television Unit: mm s Overview The AN5491K is a deflection processor IC for synchronous signal processing and screen distortion correction. It synchronizes with the input signal of High-vision, wide television, NTSC, PAL and VGA by the external binary input signal of them so that a multimedia television can be realized easily. s Features Supports the multiple-point horizontal frequency (15.7 kHz to 62.7 kHz) Horizontal duty is controllable by external voltage. Built-in full functions for correction (Horizontal and vertical: 16 items) Over-current detection, shut-down and hold-down 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 13.7±0.3 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 36.8±0.3 0.96±0.25 3.3±0.25 4.76±0.25 3° to 15° 15.3±0.25 +0.1 0.3 –0.05 SDIP042-P-0600A s Applications High-vision televisions, Wide screen televisions and Projection televisions 1.778 0.9±0.25 0.5±0.1 1 2 Corner level I2L AGC EHT-DC EHT-AC × 32 ×8 ×4 ×2 ×1 V-out VGA GND EW out H-GND DEF GND Phase out Lock det. 37 H-out 38 36 34 27 19 25 26 31 35 33 30 29 28 24 23 22 32 Lock det. fH switch input BOW V-S Upper Lower Corner correction V-LIN Trapezoid crrection Phase crrection AN5491K s Block Diagram H-AFC2 H-duty adj. 39 H VCO H-OSC 42 EW H-WID Phase V-POS out Parallel out POL V EHT-AC EHT out correction V- EHT H- EHT 4 2 5 V...
