Frequently Asked Questions
What supply voltage range does CD47HC4059 support for mixed-voltage system designs?
CD47HC4059 operates from 2 V to 6 V, making it compatible with 3.3 V and 5 V logic rails commonly used in mixed-voltage systems. At 5 V the device delivers higher drive current and faster propagation delays, while at 3.3 V it reduces power consumption, drawing typically less than 80 µA quiescent current, which is advantageous in battery-operated clock-division applications.
How is CD47HC4059 used in a phase-locked loop design as a feedback divider?
In a PLL, CD47HC4059 sits in the feedback path between the VCO output and the phase-frequency detector. By programming its division ratio via the parallel input pins, the designer sets the output frequency to N times the reference frequency. With division ratios achievable from small integers up to several thousand, the device enables fine-grained frequency steps of 1 Hz or smaller when used with a 1 MHz reference oscillator.
What are the advantages of choosing CD47HC4059 over a fixed-ratio divider for a clock generation circuit?
CD47HC4059 allows the division ratio to be changed in-system via its programming inputs, so a single device can replace a set of fixed dividers covering different ratios. This reduces BOM count by up to 4 discrete divider ICs and allows firmware to switch output clock frequencies without a hardware redesign, which is valuable in multi-rate communication equipment requiring 10 MHz, 25 MHz, and 50 MHz clock outputs from a single 100 MHz source.
What PCB footprint and package dimensions does CD47HC4059 present for SMT assembly?
CD47HC4059 is housed in a 24-pin SOIC package with 1.27 mm lead pitch and a body width of 7.5 mm, occupying roughly 15.4 mm × 7.5 mm of PCB area. This wide-body SOIC-24 footprint is compatible with standard SMT reflow profiles, and the package is available on tape-and-reel for automated pick-and-place assembly at quantities of 2500 units per reel.
