    摘要: Deflection control apparatus for registering the electron beam, rasters of electrostatic-deflection pick-up tubes of a three-tube color television camera includes a compensating voltage generator with inputs connected to receive horizontal and vertical sawtooth deflection signals provided from a deflection signal generator, and outputs providing compensating voltages to adjust for size, skew, and rotation. A combining circuit is provided to add the deflecting signals to the respective compensating voltages to generate adjusted compensating voltages for application to respective electrostatic deflection plates of certain ones of the tubes. For each adjusted deflecting signal, the combining circuit includes a transistor circuit having an input electrode coupled to receive the associated compensating voltage and an output electrode connected through a load resistor to an output of the deflecting signal generator. A pair of SEPP-arranged transistors are provided with their bases connected to the output electrode of the transistor circuit and with their emitters coupled together, through like-value emitter resistors, to a respective deflection plate of one of the tubes. The SEPP-configured transistors permit a high impedance to be presented to the deflection signal generator to minimize the power consumption thereof, and a low resistance to be presented to the deflection plates, to keep the latter from undesirably integrating the deflection sawtooth voltages.

    摘要: A refresh control circuit receives an interrupt signal, which is a request to refresh DRAM (Dynamic Random Access Memory) and which is asserted at predetermined timings. The refresh control circuit counts the number of times the interrupt signal is asserted, and asserts an interrupt subroutine start signal, which is an instruction to refresh the DRAM, in an idle state in which the DRAM is accessible from an external circuit, for a number of times that is equal to the number of times thus counted. When the interrupt subroutine start signal is asserted, a refresh circuit executes a predetermined interrupt subroutine, and supplies a refresh pattern to the DRAM.

    摘要: A frequency-voltage converting circuit 13 is composed of a switch unit including switches SW1 and SW2, electrostatic capacitive elements C and C10 to C13, and switches CSW0 to CSW3. The electrostatic capacitive elements C10 to C13 are composed of elements having mutually different absolute values of capacitance and are provided so as to cover a frequency range intended by a designer. The electrostatic capacitance values are weighted by, for example, 2. The electrostatic capacitive elements C11 to C13 are selected by, for example, the switches CSW0 to CSW3 based on 4-bit frequency adjustment control signals SELC0 to SELC3, thereby carrying out frequency switching.

    摘要: A clock signal capable of changing the frequency in a wide range and with high resolution is generated.An operational amplifier AMP1 is subject to feedback control so that the voltage of a positive input part equals that of a negative input part. The voltage of a circuit node fbck equals a reference voltage VREFI. A decoder DEC decodes control signals CNT7 and CNT6 and turns on one of transistors T2 to T5. This configuration provides feedback control so that the voltage of the circuit node fbck equals the reference voltage VREFI. This significantly reduces the on-resistances of the transistors T2 to T5 and prevents the degradation of the frequency accuracy.
