The CD4510BNSRG4 from Texas Instruments is a CMOS Programmable Frequency Divider that generally operates on 5V power supply. This programmable frequency divider is most commonly used by applications that require frequency dividers with a high degree of accuracy, such as clock and frequency generation and distribution, computer and instrumentation systems, and robotic systems.

CD4510BNSRG4 consists of two identical 4-stage binary counters which can be clocked simultaneously or independently and power consumption is very low. This programmable frequency divider is comprised of two sections, the 4-stage ripple carry binary counters (A & B) and an OR gating array. There are nine data inputs D0 to D8 and a CLK input for each section. The inputs for the OR gating array are the outputs of sections A & B and the output is the divided down frequency or the divide-by N frequency.

In operation, the 4-stage binary counter of each section receives a clock input and generates a divided down output depending on the set of data inputs D0-D8. A single clock pulse is accepted by the counter, which increments its count at the start of each clock pulse. The Clock and Data inputs accept a logic-level input signal. The counters synchronize with a logic-low level reset.

The OR gating array enables the user to create any divide-by-N number by setting the data inputs. The eight data inputs (D1-D8) set the maximum number of counts. The divide-by-N is determined by the setting of the data inputs and the number of counts per clock cycle is equal to 2N. The OR gating array determines the divide-by-N logic and generates the output pulse when the two cascaded 4-stage binary counters reach the set N count.

CD4510BNSRG4 is an easy to use device since it requires a minimal number of external components for proper operation and compatibility. The improved clocking between sections allows rigorous testing of frequencies up to 1 MHz. The device features a wide temperature range of -40 to +85° C, a low power consumption of 4 mA at 5V and is available in a variety of packages.

In conclusion, the CD4510BNSRG4 is a powerful and robust programmable frequency divider that offers the user a wide range of applications. The ability to configure the divide-by-N value with a minimal number of external components makes this programmable frequency divider highly efficient and ideal for various applications.
