Image quality adjustment of RGB interface It adjusts image quality input through 24-bit RGB interface. The supported I/O interface consists of 24-bit data, vertical synchronization signal, horizontal synchronization signal and data enable signal. It converts 24-bit RGB into YCbCr444 and makes adjustment on the contrast, brightness, sharpness, hue and intensity in the YCbCr space. The contrast, brightness and sharpness are adjusted against the luminance (Y) component and the hue and intensity are adjusted against the color difference (CbCr) component. In addition to the image quality adjustment in the YCbCr space, it is also equipped with the RGB independent gamma correction capability in the RGB space. Converting YCbCr444 to 24-bit RGB, gamma correction is made to each of the RGB components. 16 gamma curve points can be set and the intervals between those set points are linearly interpolated. When the RGBMUTE terminal is set to “High” level, the RGB output data will be all “0” from the next frame. 2. Image quality adjustment of YUV It adjusts image quality input through YCbCr422 interface. The supported I/O interfaces are ITU-R BT.656-4 and YCbCr with synchronization signal (complied with ITU-R BT.601). When the input is ITU-R BT.656-4, the output can be selected from ITU-R BT.656-4 and YCbCr with synchronization signal. However, when the input is YCbCr with synchronization signal, the output can only be YCbCr with synchronization signal. It makes adjustment on the contrast, brightness, sharpness, hue and intensity in the YCbCr space. The contrast, brightness and sharpness are adjusted against the luminance (Y) component and the hue and intensity are adjusted against the color difference (CbCr) component. 3. LVDS transmitter It outputs high-speed serial data for image quality adjustment of RGB interface in LVDS format. The data mapping to be output in the LVDS format can be changed by the register setting. When the LPDNB terminal is set to “Low” level, the LVDS transmitter part will go into power down mode. The LVDS output will become Hi-Z status. 4. 2-line serial interface 2-line serial interface slave function is embedded. The registers are accessed through this interface. The slave address is 46h (in 7-bit notation) when I2CDEV=0 and 47h (in 7-bit notation) when I2CDEV=1. The sub address is automatically incremented when consecutively accessed twice or more in read or write operation. * Slave address of 46h and 47h are in hexadecimal. * Fig.11 depicts the status when I2CDEV=0.

All rights reserved. 17/22 2011.02 - Rev.A Technical Note BU1523KV ●Procedure for turning on power supply Follow the power-on sequence of VDD→(VDDIO, I2CVDD, PVDD, LVDD) as depicted in Fig.13. The timing for power-on sequence is shown in Table 10 however, it is recommended to make the intervals of tPWUV2, tPWUV and tPWUVL as short as possible. Until after voltage is applied to all the power sources, the levels of all the input pins are fixed and the low level is input onto RESETB, the internal status and pins remain unstable. Remove the reset after inputting the clock (RGBCKI, YCKI). When the clock (RGBCKI, YCKI) is to be temporarily halted during the operation, apply the reset after the clock (RGBCKI, YCKI) stopped to fix the operation, then follow the power-on sequence and remove the reset after inputting the clock (RGBCKI, YCKI). 2-line serial interface is enabled for communication after the reset (RESETB) is removed. However, racing may be caused if the rising edge of the reset (RESETB) signal and the signal change of 2-line serial interface occur at the same time. Ensure not to allow the rising edge of the reset (RESETB) signal and the signal change of 2-line serial interface to occur at the same time. Design the system to avoid racing and system malfunction when the internal status and pins are unstable. * The reset is also possible by the software reset (SRST_R_IP, SRST_Y_IP, SRST_LVDS).

All rights reserved. 19/22 2011.02 - Rev.A Technical Note BU1523KV ●PCB Design Guideline for LVDS ・Interconnecting media between Transmitter and Receiver ( i.e.PCB trace, connector, and cable) should be well balanced. (Keep all these differential impedance and the length of media as same as possible.). ・Locate by –pass capacitors adjacent to the device pins as close as possible. ・Minimize the distance between traces of a pair. (S1) to maximize common mode rejection. See following figure. ・Place adjacent LVDS trace pair at least twice (>2 x S1) as far away. ・Avoid 90 degree bends. ・Minimize the number of VIA on LVDS traces. ・Match impedance of PCB trace, connector, media (cable) and termination to minimize reflections (emissions) for cabled applications (typically 100Ω Differential mode characteristic impedance).

All rights reserved. 20/22 2011.02 - Rev.A Technical Note BU1523KV ●Notes for use (1) Absolute Maximum Ratings An excess in the absolute maximum ratings, such as supply voltage, temperature range of operating conditions, etc., can break down devices, thus making impossible to identify breaking mode such as a short circuit or an open circuit. If any special mode exceeding the absolute maximum ratings is assumed, consideration should be given to take physical safety measures including the use of fuses, etc. (2) Recommended Operating conditions These conditions represent a range within which characteristics can be provided approximately as expected. The electrical characteristics are guaranteed under the conditions of each parameter. (3) Reverse connection of power supply connector The reverse connection of power supply connector can break down ICs. Take protective measures against the breakdown due to the reverse connection, such as mounting an external diode between the power supply and the IC’s power supply terminal. (4) Power supply line Design PCB pattern to provide low impedance for the wiring between the power supply and the GND lines. In this regard, for the digital block power supply and the analog block power supply, even though these power supplies has the same level of potential, separate the power supply pattern for the digital block from that for the analog block, thus suppressing the diffraction of digital noises to the analog block power supply resulting from impedance common to the wiring patterns. For the GND line, give consideration to design the patterns in a similar manner. Furthermore, for all power supply terminals to ICs, mount a capacitor between the power supply and the GND terminal. At the same time, in order to use an electrolytic capacitor, thoroughly check to be sure the characteristics of the capacitor to be used present no problem including the occurrence of capacity dropout at a low temperature, thus determining the constant. (5) GND voltage Make setting of the potential of the GND terminal so that it will be maintained at the minimum in any operating state. Furthermore, check to be sure no terminals are at a potential lower than the GND voltage including an actual electric transient. (6) Short circuit between terminals and erroneous mounting In order to mount ICs on a set PCB, pay thorough attention to the direction and offset of the ICs. Erroneous mounting can break down the ICs. Furthermore, if a short circuit occurs due to foreign matters entering between terminals or between the terminal and the power supply or the GND terminal, the ICs can break down. (7) Operation in strong electromagnetic field Be noted that using ICs in the strong electromagnetic field can malfunction them. (8) Inspection with set PCB On the inspection with the set PCB, if a capacitor is connected to a low-impedance IC terminal, the IC can suffer stress. Therefore, be sure to discharge from the set PCB by each process. Furthermore, in order to mount or dismount the set PCB to/from the jig for the inspection process, be sure to turn OFF the power supply and then mount the set PCB to the jig. After the completion of the inspection, be sure to turn OFF the power supply and then dismount it from the jig. In addition, for protection against static electricity, establish a ground for the assembly process and pay thorough attention to the transportation and the storage of the set PCB. (9) Input terminals In terms of the construction of IC, parasitic elements are inevitably formed in relation to potential. The operation of the parasitic element can cause interference with circuit operation, thus resulting in a malfunction and then breakdown of the input terminal. Therefore, pay thorough attention not to handle the input terminals, such as to apply to the input terminals a voltage lower than the GND respectively, so that any parasitic element will operate. Furthermore, do not apply a voltage to the input terminals when no power supply voltage is applied to the IC. In addition, even if the power supply voltage is applied, apply to the input terminals a voltage lower than the power supply voltage or within the guaranteed value of electrical characteristics. (10) Ground wiring pattern If small-signal GND and large-current GND are provided, It will be recommended to separate the large-current GND pattern from the small-signal GND pattern and establish a single ground at the reference point of the set PCB so that resistance to the wiring pattern and voltage fluctuations due to a large current will cause no fluctuations in voltages of the small-signal GND. Pay attention not to cause fluctuations in the GND wiring pattern of external parts as well. (11) External capacitor In order to use a ceramic capacitor as the external capacitor, determine the constant with consideration given to a degradation in the nominal capacitance due to DC bias and changes in the capacitance due to temperature, etc. (12) Rush current For ICs with more than one power supply, it is possible that rush current may flow instantaneously due to the internal powering sequence and delays. Therefore, give special consideration to power coupling capacitance, power wiring, width of GND wiring, and routing of wiring. www.rohm.com © 2011 ROHM Co., Ltd.
