Frequently Asked Questions
What supply voltage range does the HCC4046BDG support, and how does that compare to commercial CMOS PLL alternatives?
The HCC4046BDG operates from 3 V to 18 V, which is the full CMOS 4000B logic supply range. Commercial alternatives like the CD4046B share the same voltage window, but the HCC variant is radiation-hardened, making it the correct choice for satellite or space-probe power rails where total ionizing dose can exceed 100 krad.
Which space or defense applications are best served by the HCC4046BDG PLL?
This device is well suited to satellite on-board frequency synthesis, military secure-radio clock recovery, and avionics data-bus timing generation where radiation tolerance is mandatory. Its ceramic DIL-16 hermetic package withstands temperature excursions from -55 °C to +125 °C and vacuum outgassing requirements typical of low-Earth-orbit payloads.
How many phase comparators are integrated in the HCC4046BDG and what loop filter capacitor range does the VCO typically require?
The HCC4046BDG integrates 2 independent phase comparators (PC1 XOR type and PC2 edge-triggered type) sharing a single VCO. The external loop filter capacitor for the VCO typically ranges from 100 pF to several microfarads depending on the target lock frequency, while the timing resistors set the center frequency between 1 Hz and 1.4 MHz at 5 V.
Is the HCC4046BDG recommended as a drop-in replacement for the standard CD4046B in a non-space application?
Yes, the HCC4046BDG is pin-for-pin compatible with the CD4046B in the standard 16-pin DIP footprint and supports the same 3 V to 18 V supply. However, the ceramic hermetic DIL-16 package is larger and costlier than the plastic SOIC or PDIP versions, so the HCC variant is justified only when radiation hardness or MIL-grade temperature range of -55 °C to +125 °C is required.
