74HC4046 Model Development
I have been notified by Helmut Sennewald that the LTspice encryption
process hides the node sequence. So please revisit... http://www.analog-innovations.com/SED/HC4046_SUB.zip for a corrected version. This is just the VCO portion for now, and just the variable part; suitable only for LTspice. Please try it out and let me know your comments, etc. Since I'm new to working with LTspice, please send me any error messages, so I can refine my skills :-} ...Jim Thompson -- | James E.Thompson, CTO | mens | | Analog Innovations, Inc. | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | Phoenix, Arizona 85048 Skype: Contacts Only | | | Voice480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | I love to cook with wine.

Looking forward to trying it out! My aim is to make the model as close to the silicon as possible. For amusement, since it had been mentioned, I'm also doing the uA741 at the same time. It may be done tomorrow or Monday, since it's rather easy. The 4046 will take awhile to get all the pieces working together. ...Jim Thompson -- | James E.Thompson, CTO | mens | | Analog Innovations, Inc. | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | Phoenix, Arizona 85048 Skype: Contacts Only | | | Voice480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | I love to cook with wine.

You want to earn money with it, then spend some money for testers. I GAVE you a model. I didn't charge for it. I encrypted it to conceal my "tricks of the trade". I know my model works under LTspice... http://www.analog-innovations.com/SE...SUB_SIM_LT.pdf my submission was simply to make sure it also works after encryption. Quite frankly I don't give a rat's ass whether you use the model or not.

I found the Philips/NXP variant a very well behaved device, whereas others had/have poor VCO control linearity etc. I'm just going from reports here, primarily Phil Hobbs' bad experiences. ALL of the data sheets look wonderful ;-) I can certainly think of ways to improve it, particularly the current mirrors, though a complete architecture change could easily eliminate lots of the non-linearity issues. Whoever rolled the CMOS copy totally missed an important point, don't dump the capacitor into a substrate diode. ...Jim Thompson -- | James E.Thompson, CTO | mens | | Analog Innovations, Inc. | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | Phoenix, Arizona 85048 Skype: Contacts Only | | | Voice480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | I love to cook with wine.

See the list of datasheet references I posted in the other HC4046 thread a few days ago. Whilst I agree that each manufacturer gives a range for each parameter, my experience is that each manufacturer produced devices which were amazingly consistent, but wildly changing from one manufacturer to another. I recall that each manufacturer specified their 74HC4046 very differently to show theirs in the best light. One problem I had years ago was that one version produced over 25MHz irrespective of R and C with a control voltage at +5V, causing my counters to fail and the whole PLL to fall over! -- Mike Perkins Video Solutions Ltd www.videosolutions.ltd.uk |
