.. buffers occupy small footprints on the interface’s PCB (printed-circuit board). For operation at serial-interface clock rates approaching IC 1 ’s 26-MHz maximum, optimize the values of resistors R 1 through R 6 to provide ...
.. circuit by feeding its output back to its reset pin through an RC network. IC 1 outputs a high on the rising edge of the clock by tying its J input high and its K input low. The pushbutton switch connects between the clock input of IC 1 ...
.. side of the I 2 C bus; SDA 1 and SCL 1 are on the slave device’s side. It is fairly easy to optoisolate the clock line because it is unidirectional, from the master to the slave device. A P-channel MOSFET, Q 3 , provides the ...
.. consumer electronics applications, which tend to be lower in frequency and less demanding than typical clock-buffering applications, inexpensive high-speed op amps (~100-MHz bandwidth) can offer an attractive option in ...
.. time constant, a zero shifts into the register. If the low state is short, then a one shifts into the register. The clock and data signals thus combine into one signal. A lowpass filter separates the clock and data signals (Figure ...
.. circuit in the Figure 1, however, can vary the ramp frequency from less than 1 Hz to about 30 kHz just by varying the input clock from 100 Hz to about 6 MHz. The output was measured at a voltage of 5 V peak, but it can be adjusted as well, ...
.. plus ground, the host controller can address the target device and exchange data, whereas SPI requires three wires data, clock, and chip-selection plus ground. Multiple SPI-target devices can share data and clock lines, but each device ...
.. resolution. Alternatively, you can take those three bits from the top of the original PWM duty-cycle value, multiplying its clock rate by eight. You still get the 8:1 ripple reduction, but the increased clock rate pushes PWM noise further ...
.. a pseudo sine wave. In operation, the sine-wave output appears across inductor L in a series LC circuit. An external clock source produces gate drive for transistor Q at a frequency that's lower than the LC circuit's natural ...
.. rise-time, and faster PWM frequency translates to lower resolution when achieved by reducing the counter size at a given clock frequency. I am going to talk about an interesting Design Idea that focuses on lowering the ripple of PWM DACs ...
