The MC14046BFG is an integrated circuit (IC) designed by Motorola, now a sector of Freescale Semiconductor, and is considered a low-cost clock/timing circuit capable of producing multiple clock outputs. It is designed to produce various outputs of differing accurate clock frequencies, which can be used in a variety of digital circuits and devices, including data acquisition systems, integrated portable systems, computer and cell phone applications, wireless communications systems, digital television and data display systems, pulse width modulators, and frequency synthesizers.
The MC14046BFG is available in both dual package and quad package versions, with the quad package version being slightly larger than the dual package version. The dual version is referred to as the MC14046F. The ICs have built-in oscillators that provide high accuracy reference frequency outputs, as well as a set of divider registers for creating the desired oscillations or frequencies. The quad version has four banks of divider registers whereas the dual has two.
The oscillators in the MC14046BFG are designed to work in either a push-pull or single-ended mode. Additionally, the oscillators are designed such that they can operate in either in a signal or be disabled either manually or through electronic control. The oscillators provide outputs of various frequencies, with some providing non-multiple frequencies. The ICs also include sensing circuitry and voltage regulators, allowing them to remain in a particular state even after a power-on or power-off situation.
The MC14046BFG portion of the IC is responsible for controlling the multiple divider registers used to generate the desired clock frequencies. It provides a selection of frequencies, from very low multiples to high multiples, depending on the need of the application. The main output divide settings range from 10^2 to 10^7, with the lower setting allowing the IC to generate frequencies up to 10MHz. The output divide settings also allow the IC to be tailored to the exact needs of the application.
The MC14046BFG also contains automatic-holding registers and an output enable (OE) pin for reset signals. These features allow for simpler programming and easier control of the output frequency signals. Additionally, there are single serve and double serve options available for the output of a single clock frequency from one of the oscillators. The single serve allows a clock output of either 1.0MHz or 2.0MHz and the double serves takes the output from two of the oscillators and combines them in a divide-by-N configuration, up to a maximum of N=32.
In addition to the features listed above, the IC contains a number of other features that are essential to its operation. This includes the power-on reset (POR) pin to ensure a clean power up and start operation, the reset output pin, a write protect pin that allows the protection of the registers on the IC, and the clock oscillator disable (COD) input. All of these features are necessary to ensure the proper operation and accuracy of the MC14046BFG.
In conclusion, the MC14046BFG is an integrated circuit designed to provide multiple clock frequencies to a variety of digital devices. It is designed as a low-cost timing solution and is available in both dual and quad package versions. Its internally incorporated oscillators and dividers allow the user to precisely generate desired clock outputs and its additional features, such as the POR pin and output enable (OE) pin, ensure easy and accurate application and operation.
