Manufacturer:STM Description:The 50% point of sync is determined by using two identical resistors to divide the voltage between sync tip and back porch. The importance of precision sync tip clamping may be appreciated here, since the sync tip voltage is used in deriving the 50% slicing level. The back porch voltage is derived through an internal integrate and hold circuit that is gated by the Back Porch output signal. By integrating over the entire back porch period, the accuracy and noise immunity of acquired back porch voltage is greatly improved when compared to systems using simple sample and hold techniques. |
