The NBC12430AFNR2G Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers is a high-frequency clock generator and fanout device which features both an incredibly low jitter of 170.6 fs peak-to-peak and low supply current of 220 μA/MHz. This makes it an ideal choice for high-speed data transmission used in applications such as computer networks, communications systems, server systems, and test and measurement systems. The device features a two output banks of two 5-MHz crystal oscillators running in parallel, allowing for a generation of two 5-MHz outputs of low-power, low-jitter clock signals. The NBC12430AFNR2G is also capable of producing a reduced frequency output (pulled) from either output bank that is as low as 200 kHz and is adjustable in steps of 120 kHz, for a total of 11 output frequencies. In addition to the two output banks of 5-MHz crystal oscillators, the device also features a narrower tuning range than competing products, allowing for finer tuning of frequency and phase, as well as an improved phase noise of -84 dBc/Hz at 1MHz offset.The NBC12430AFNR2G utilizes a Phase-Locked Loop (PLL) to achieve its low-jitter and low-power performance. The device has an internal reference clock oscillator which can be requested as a digital output and can be programmed to either 5-MHz or 12-MHz depending on the requirements of the application. The reference clock signal then passes through a programmable divider to generate a signal that is locked in phase to the input reference. This signal is then compared against the signal from the parallel arrangement of two 5-MHz crystal oscillators, and a phase adjuster ensures that the two signals are in phase. The output frequency is then adjusted accordingly and the device is able to generate low-jitter, low-power clock signals.The NBC12430AFNR2G is easy to use and configure. It can be operated in either pin-strap or serial-controlled mode, allowing for a convenient and flexible configuration and operation for users. The device requires very low external components and requires only 3V to 3.6V supply voltage and a crystal or ceramic resonator for operation.In terms of applications, the NBC12430AFNR2G can be used in various applications requiring a high-frequency clock signal source. This includes computer networks, communications systems, server systems, and high-speed test and measurement equipment. It is also suitable for PCIe, Ethernet, Gigabit Ethernet, SONET/SDH, and Low-Speed Interchip Bus applications.Overall, the NBC12430AFNR2G is an ideal choice for applications requiring a low-jitter, low-power clock signal. It features an incredibly low jitter of 170.6 fs peak-to-peak and a low supply current of 220 μA/MHz. The device also features two output banks of two 5-MHz crystal oscillators running in parallel, allowing for a generation of two 5-MHz outputs of low-power, low-jitter clock signals, as well as a narrower tuning range than competing products. In addition, the device is also easy to use and configure and requires very low external components for operation. This makes it an ideal choice for computer networks, communications systems, server systems, and high-speed test and measurement equipment.
