MY51T Datasheet
MY51T Price VIDEO INPUT SECTION A composite signal of the selected standard is applied to the device via a coupling capacitor also acting as the clamp storage capacitor. A minimum level clamp is used to DC restore the video signal in the lC to an internally defined reference voltage. The AGC will give a constantoutputlevel with input signals between 0-5 and l-5 Vp-p. If a controlled lVp-p video signal is available, the AGC may be disabled, in which case a white clip circuit is switched in, to prevent possible overmod ulation. Selection of negative or positive modulation is via a single pin (14). The voltage on this pin controls an offset which is fed to the UHF mixer, thus determining both modulation depth, and sense of modulation. MY51T on stock When power is applied the (internal) synchronous enable flip-flop will be in a state such that the outputs will be in the high-impedance state. In order to enable the outputs, a clock must occurand the ES input pin must be LOW atleast a set-up time prior to the clock LOW-to-HIGH transition. The E input may then be used to enable the outputs.
