.. potentiometers controlled by a 16-bit code via a three-wire serial interface. To set the LED current, drive RST high and clock 16 bits into the D terminal of IC 1 , starting with the LSB. Each pulse at CLK enters a bit into the register. ...
.. has a number of PWM outputs and one analog comparator. The PWM we will use can be clocked at various rates and we want to clock it fast as this will make the filtering easier. It will also speed up the time for the filter output to settle ...
.. that F1a will ignore the inevitable S1 bounce. Meanwhile the resulting clean transition delivered to F1b’s pin 11 clock pin causes it to reliably toggle, flipping ON if it was OFF and flopping OFF if it was ON where it remains ...
.. (or EXNORed) and fed back to the input, producing a pattern of bits which appears random though it repeats every 2 23 1 clock cycles, which at a clock rate of 240 kHz is about every 35 seconds. (That “ 1” represents the ...
.. vs. C X (at R S = 10 kΩ, 2.5 V supply) is reported in Figure 4. The output RC filter is effective in eliminating clock noise. The plot shows output vs. frequency for C X = 0 and C X = 2.2 nF/ 10 nF/ 47 nF/ 68 nF. Figure 4. Output ...
.. voltage, with six analog levels, corresponding to the states of the electronic dice. From left to right, we see the clock oscillator, a charge pump and a reset circuit for this charge pump. We will now discuss those parts in that ...
.. pulses by onboard CTP logic limits maximum count rate to a fraction (typically ¼) of the µC’s internal clock. Thus, for a 20-MHz internal clock, 5 MHz is the fastest achievable CTP count rate. Sorry, Kong. Of course, an ...
.. 3 to 36 V. Figure 1. By using a high-side current-sense amplifier IC (IC 1 ) in an unconventional manner, you can combine clock or data signals with dc power in cables. Figure 1 depicts a subsystem that receives power from its host system ...
.. due to a high-level reset signal from IC 3 driving IC 4 , a NOR gate. After the first low-to-high transition on the SCK (clock-signal) line, a rising edge from IC 3 ’s /WDO (watchdog output) sets the flip-flop and pulls current ...
.. an 256/32 MHz = 8 µs PWM period. The capacitances will of course need proportional adjustment for different PWM clock frequencies. Meanwhile 1k Dpot U2 provides an SPI controlled, 8-bit resolution, 0 to 2.5 V lsbyte contribution ...
