7 / 43 page  Compatibility with LM1237 and LM1247 (Continued) TABLE 2. LM1253A/LM1237 Compatibility DAC Bias Outputs LM1236 Pin: DAC 1 DAC 2 DAC 3 DAC 4 Assignment: Blue Green Red Brightness OSD vs Video Intensity The OSD amplitude has been increased over the LM1237 level. During monitor alignment, the three gain registers are used to achieve the desired front of screen color balance. This also causes the OSD channels to be adjusted accord- ingly, since these are inserted into the video channels prior to the gain attenuators. This provides the means to fine tune the intensity of the OSD relative to the video as follows. If a typical starting point for the alignment is to have the gains at maximum (0x7F) and the contrast at 0x55, the resultant OSD intensity will be higher than if the starting point is with the gains at 0x55 and the contrast at maximum (0x7F). This tradeoff allows fine tuning the final OSD intensity relative to the video. In addition, the OSD contrast register, 0x8438 [4:3], provides 4 major increments of intensity. Together, these allow setting the OSD intensity to the most pleasing level. ESD Protection The LM1236 features a 3.0 kV ESD protection level (see (Notes 4, 13)). This is provided by special internal circuitry which activates when the voltage at any pin goes beyond the supply rails by a preset amount. At that time, the protection is applied to all the pins, including SDA and SCL. www.national.com 7 |
