4 / 5 page  Applications Information (Continued) AR OSC_IN resistor value of 50k Ω with a C OSC_IN capacitor value of 0.01µF and a V DD value of 5.00V would produce a typical oscillator frequency ( f OSC) of about 1200Hz. The f OSC signal is divided by 16 before it is presented at the BP_OUT pin. For this example the approximate BP_OUT frequency will be f OSC/16, or about 75Hz. The BP_IN pin of the MM145453 can be used with an externally supplied signal, provided it has a duty cycle of 50%. Any deviation from a precise 50% duty cycle will result in an offset voltage on the LCD. The use of an external clock allows synchronizing the display drive with AC power, other internal clocks, or DVM integration time to reduce interfer- ence from the display. When using an external clock for the back plane drive the internal oscillator should be disabled by connecting the OSC_IN pin directly to ground. This will prevent possible internal oscillations, and reduce device dis- sipation. The MM145453 is a pin out variation of the MM5453. For additional applications information please refer to the MM5453 data sheet. Input Data Format 10128304 FIGURE 3. www.national.com 4 |
