Working Principle

The IDT3CP0C02-48NSGET is a programmable oscillator. Its robust design allows it to program precisely a wide range of clock frequencies, outputs and dividers. Clocking frequencies range from 0.01Hz to 300MHz with precise accuracy. Its intrinsic jitter is down to 0.75ps peak-to-peak from 1MHz to 40MHz and only 1.5ps peak-to-peak from 40MHz to 150MHz.

The device comes with four independent output pins (1, 2, 3, 4). These outputs could be divided by 1, 2, 4, 8, 16, 32 and 64. For example, if the master clock frequency is 100MHz, each output will take a division value and generate corresponding output frequency, i.e., Outpin1: 100MHz, Outpin2: 50MHz, Outpin3: 25MHz and Outpin4: 12.5MHz.

In addition to its four independent outputs, the IDT3CP0C02-48NSGET has an external feedback input CH2 pin that provides an additional option of generating a digital output frequency. The CH2 pin takes a logic low (0V) during the master clock cycle and present a logic high (3V) for CH2 cycle. The CH2 divide ratio is programmable from 1 to 8.

The IDT3CP0C02-48NSGET also offers fast programming options. It comes with an external loading pin (bit 1) that, when taken low and held for 2 to 20µs, programs the input pins to generate a new operating frequency within 10ms. This fast programming is particularly useful for applications where timing requirements must be changed in milliseconds or less.

The IDT3CP0C02-48NSGET also offers programmable power-up/down programming and holdover features, allowing you to safely power up/down devices without recalculating and reconfiguring timing cycles. This versatile programmable timer is the perfect solution for a variety of needs.

Conclusion

The IDT3CP0C02-48NSGET is an ideal clock generator of choice for many high-speed timing and switching applications. Its innovative design addresses multiple power-up and down needs while providing robust features such as low jitter, precise accuracy and fast programming. With an integrated 4-output and a programmable external feedback CH2, this device provides quick, hassle-free clock synchronization to enable the development of the highest performance, reliable and cost-effective products for a wide range of applications.
