Thu Apr 29, Still need help with l ic circuit. Nov 17, 7. It does get hot though, which means it is using quite abit of current I think about mA. I heard that it wasn’t too expensive to get crystals made so I thought about getting them made for the 65C02 and WDC 65CS and 7s4124 other processors.

I’d say this is good for 50 MHz and more, even MHz. If the frequency datasneet to high, you can use 5 or 7 gates. Apr 14, 7, Posted by keithg in forum: Quote of 74s1124 day. Your name or email address: Despite this, I have always been intrigued by digitally controlled clock generation, but PLLs were always above my understanding.


See figure 2 of the datasheet.

Embedded Systems and Microcontrollers. I remember reading about it in these forums awhile back how someone used an AVR for an excellent programmable clock source. Oct 2, darasheet, 5, Do you already have an account? These will work to 85MHz. Do you already have an account?

No, create an account now. Really advanced constructors will exceed the maximum rated processor speed – but if you do this you have to be prepared for things to fail. Definitely do the inputs, but with CMOS logic the outputs should be driven hard enough to be a non-issue, and I’d rather not deal with the possibility of accidentally activating the device’s clamp diodes.

Adjacent rows of course have a rather high capacitance!! Discussion in ‘ General Electronics Chat ‘ started by dumindu89Oct 12, Dividers are obviously lacking resolution darasheet near the input clock speed Thu Apr 29, 3: I tried using a inverter see attachment for configurationand after removing the capacitor and lowering the value of R to the point just before oscillation stopped, I measured a frequency of 5 MHz with my oscilloscope.

Proto PCB should have single hole pads, not strips.

Nov 17, 4. It used an input of 80 or MHz and there might have been a PLL to generate a lot more frequencies than 74s214 could merely by changing a divisor. The transmitter coil inserted with one pin only! What speeds do you recommend for a beginner and what speed do you recommend for someone who knows what they are doing?


Breadboards aren’t really good. Has anyone here in the forums used an Atmel IC for high speed, high resolution clock generation? Dec 10, 50 3.

Datasheet used to look at a CD datasheet, I still remember the part without looking it up! Based on the national time clock signal. Users browsing this forum: Discussion in ‘ General Electronics Chat ‘ started by bobNov 17, And reduced down to 2. More experienced constructors can run up to the maximum rated clock speed for the processor 14MHz with current WDC devices.

Connect the enable pin to ground. The reason for connecting the unused sections of the hex Dataseet inverter to the power and ground planes as 744s124 above is to effectively reduce the power-lead inductance for better behavior at high speeds, since 74xx DIPs’ pinouts were set to be at the corners decades ago before designers could foresee rise times reaching such speeds that the lead inductance would be a problem.

Also the stability of a RC oscillator will be far from ideal.
