1 ics for tv publication date: november 2001 sdb00080aeb AN2526NFH automotive lcd tv signal processor ic overview the AN2526NFH is a video signal processing ic with an lcd's 5 v-source driving power supply for tft color lcd (normally white type), and it supports ntsc and pal systems. the main circuitry of this ic includes video- signal processing circuit, color signal processing circuit, interface circuit, synchronizing circuit and many color quality adjusting circuits. this ic converts the composite video signal or separated y/c signal or rgb signals into rgb signals available for tft color lcd. features ? supply voltage: 5 v/7.5 v ? built-in lcd's 5 v-source driving power supply ? low consumption power (typ. 260 mw) ? supporting ntsc and pal ? supporting composite, component and color differen- tial signal input ? video signal | analog rgb (2 systems) one is for osd (analog/digital). ? each mode setting is possible with 3-wire or i 2 c bus control. ? electronic volume (d/a converter) built in ? contrast/brightness/ correction circuit built in ? horizontal and vertical display position adjustment are possible by serial control. ? package: qfp-64hp10l (10 10 1.95 mm) ? difference from the an2526fh compared to the an2526fh, the sync. system gain is increased in no signal input. this may cause the picture on the screen to be swaying horizontally. so we cannot recommend this ic to be used in the set with no-signal input mode. applications ? 4 inches to 7 inches middle size tft lcd equipment of normally white, of such as in-car tv, an lcd monitor for car navigation system. qfp064-p-1010 unit: mm 10.00 0.20 48 33 32 17 16 1 64 49 12.00 0.20 10.00 0.20 0.10 0.10 12.00 0.20 1.95 0.20 (1.25) (1.25) 0.50 0.18 + 0.10 ? 0.05 0.15 + 0.10 ? 0.05 seating plane (1.00) 0.50 0.20 0 to 10 note) the package of this product will be changed to lead-free type (qfp064-p-1010a). see the new package dimensions section later of this datasheet.

AN2526NFH sdb00080aeb 26 technical data serial data control in addition to its serial control by the conventional three-wire method, the AN2526NFH can be controlled by the i 2 c bus. the transmission method is selected by the voltage to be applied to pin 46. three-wire control mode: pin 46 = low-level (connect to gnd) i 2 c bus mode: pin 46 = high-level (pin 41: connect to v dd ) it is recommended that the serial data is transferred during a vertical blanking period. 1. three-wire control mode a serial data is of three-line system transmitting three kinds of signals of data, shift clock and load pulse independently. the data to be transmitted is made up by 12 bits in total of address (4 bits) and data (8 bits). the dac is composed of four blocks of serial-parallel conversion, address decoder, data latch and ladder resistors, enabling to control 16 channels in total. further, the mode setting such as the input signal switching is done by a serial data to reduce the pin count. 1) serial data format d11 d10 d9 d8 d7 d6 d5 d4 d3 d2 d1 d0 address block data block 2) serial data input timing chart timing chart expanded diagram d11 d10 d2 d1 d0 pin 48 s-data pin 47 sclk pin 49 ld pin 47 sclk t ckh t ckl t dch t chd t chl t ldh t ldc t cr t cf pin 48 s-data pin 49 ld
