Mar 19, 2018 · Re: Using 4046-Type PLLs Successfully. Now, first wrinkle -- and, a fatal one I think, as, at a glance, I don't see this enumerated in the article -- CD4046 is the "original and still best", and 74HC4046, and 7046 and 9046, are the knock-off substitutes.

HC4046 Summary of contents Page 1 High-Performance Silicon-Gate CMOS The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. package. Please refer to the LPS35HW datasheet for package outline and mechanical data. Figure 2: Package rendering The LPS35HW is intrinsically waterproof thanks to the ceramic cavity base and the potting gel that covers the sensible element and the readout electronics. Strange parameters in datasheet of 74HC4046. Ask Question Asked 3 years, 10 months ago. ... but HC4046 not, it shows here to avoid wrong using, ... Aug 26, 2011 · I kept upping the timer capacitor, up to almost 1 microfarad (!), and it still would run ssssuuuuppppeeeerrrr fast at the high end, but increasingly slower at the low end. Weird. I am still baffled how the silicon did this, but I did learn the fix, by comparing the old, Texas Instrument datasheet with a newer one, by NXP. The 74HC4046A; 74HCT4046A is a phase-locked-loop circuit that comprises a linear VCO and three different phase comparators (PC1, PC2 and PC3). It has a common signal input amplifier and 74HC4046 datasheet, 74HC4046 pdf, 74HC4046 data sheet, datasheet, data sheet, pdf, Fairchild Semiconductor, CMOS Phase Lock Loop

Jun 18, 2010 · Honestly, when the datasheet has this as a specific example, and a simple google search yields yet more information, WHY do you ask us first? Please do a modicum of your own research first.

Attachments cd4046 vco.pdf CD4046 or 74 HC4046 PSPICE MODEL. Is there anybody who has the SPICE (PSPICE) Model of cd 4046 or 74HC4046 PLL ? I can't find it on manufacturers web site. Re: Basic 74HC4046 PLL questions - lock range « Reply #6 on: March 04, 2016, 01:03:48 am » The reason that I been monitoring pin 10 instead of pin 9 on the original circuit at higher frequency with the counter in the loop was because my scope probe was introducing noise into the LPF (something was causing the PLL to not lock).
