Webb19 mars 2009 · The output clock quality of a PLL circuit is highly sensitive to power supply noise. IC manufacturers define PLL power filtering requirements by specifying the maximum voltage noise ripple at the power pins, say, 10mV, as well as the filter attenuation required of such noise as a function of the frequency, for example, -3dB at 50 kHz. WebbA circuit which includes 74LS or 74HCT ICs must have a 5V supply. A 74LS output cannot reliably drive a 4000 or 74HC input unless a 'pull-up' resistor of 2.2k is connected between the +5V supply and the input to correct the slightly different logic voltage ranges used. Note that a 4000 series output can drive only one 74LS input. エリア 燕 https://detailxpertspugetsound.com
