- Dhananjay Gadre.. microcontroller are in C and use the open-source AVR GCC compiler. The AVR ATtiny13 microcontroller operates at an internal clock frequency of 9.6 MHz without an internal-clock-frequency divider, so the PWM frequency is 9.6 MHz/256 = 37.5 ...Feb 15, 2019
- .. and operating frequency are resistor programmable and the operating frequency can be set to synchronize to an external clock. The LTM8074 also features programmable soft-start, output voltage tracking, power good indicator and enable ...Jan 30, 2019
- Frank Cox.. highpass filters because of their sampled-data nature. Sampled-data systems generate spurious frequencies when the sampling clock of the filter and the input signal mix. These spurious frequencies can include sums and differences of the ...Nov 2, 2018
- .. selectable lowpass/bandpass switched-capacitor filter removes the harmonics from a square wave you apply to its inputs. The clock for the MSFS5 is 100 times the input square wave. The 74HC390 and 74HC74 form a divide-by-25 and a ...Oct 25, 2018
- .. sharp rolloff, but the passband is too narrow for a typical application. The filter center is 50 times the center-frequency clock and, according to the datasheet, can differ by 0.9% from the calculated value. If we allow the filter pass area ...Aug 2, 2018
- Steve Hageman.. 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 ...May 10, 2018
- Santosh Bhandarkar.. 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 ...Apr 17, 2018
- .. 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 ...Apr 10, 2018
- John Ardizzoni.. 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 ...Apr 2, 2018
- Rex Niven.. 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 ...Mar 19, 2018
