AN2526NFH
Automotive LCD TV signal processor IC
I 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 videosignal 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.

I 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 differential signal input * Video signal analog RGB (2 systems) One is for OSD (analog/digital). * Each mode setting is possible with 3-wire or I2C 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 x 10 x 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.

I Usage Notes
* You are required to study adequately before using it in PAL. * If the duty of PWM output is set to other than 0% to 100%, the jitter of the HD out put increases. So, confirm the horizontal jitter amount on the screen of the set you introduce the PWM function into.

AN2526NFH
I Technical Data
Serial data control In addition to its serial control by the conventional three-wire method, the AN2526NFH can be controlled by the I2C 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) I2C Bus mode: Pin 46 = High-level (Pin 41: connect to VDD ) 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

The delay time of pin 30 output to video signal is likely to vary according to an external constant connected to pin 45. For an external constant, you are required to evaluate adequately the characteristics in weak electric field. Though the horizontal sync signal output adjustment range is designed by referring to the center of pin 30 output pulse, there would be some error according to VCO free-run frequency.

2. I2C control mode A serial data is capable of transferring 9-bit unit of 8-bit transfer data and 1-bit answering data using two kinds of signal lines of data and shift clock. When a slave address after setting a start condition matches the address on the IC side, you can receive the data to be transmitted from then. Once the stop condition is set up, the next transmitting data will be ignored until the start condition is set up. There are two kinds of transfer mode: an auto-increment mode which does not transmit sub-address, and data upgrade mode which transmits sub-address + data by 2 bites. The typical models of transmitting sequence are shown below: 1) Start condition When the S data changes from high-level to low-level at SCLK = high-level, a data receiving mode becomes available. 2) Slave address transfer The slave address of the AN2526NFH is 88h at pin 49 = high-level and 8Ah at pin 49 = low-level.
Pin 48 S-data 1 Pin 47 SCLK Sub address transfer Start condition Acknowledge bit 2 3 4 5 6 7 8 9 1 2
3) Sub address transfer When a data transfer mode bit is 0, all the serial data columns transferred until a stop condition is set is regarded as the data block.
