DIVISION SYNCHRONIZING CIRCUIT OF MONITOR HIGH VOLTAGE GENERATING CIRCUIT

摘要

PURPOSE: A division synchronizing circuit of a monitor high voltage generating circuit is provided to divide a synchronous signal of the high voltage generating circuit by two and synchronize the divided frequency so as to reduce noise on a cathode ray tube. CONSTITUTION: A division synchronizing circuit of a monitor high voltage generating circuit includes a dividing circuit(100) and a frequency synchronizer(200). The dividing circuit(100) outputs original synchronous signal when a division enable signal is low and divides the synchronous signal by two when the division enable signal is high. The frequency synchronizer(200) synchronizes the frequency which is divided at the dividing circuit. The dividing circuit includes a transistor and a first and second flip-flops. The transistor enables the first and the second flip-flops with response to the division enable signal.
