Clock and timing applications are a core component of most circuits, providing predictable and repeatable timing signals for reliable operation. The NB2309AC1HDG is an extremely versatile clock generator, PLL, and frequency synthesizer that combines multiple functions into one small package to optimize space and cost.

The device is designed to meet the needs of a variety of applications, including clocking and timing, low-speed jitter attenuation, and crystal oscillator replacement. It is well-suited for use in broadcast, digital media, and networking equipment, as well as other applications where low-jitter and low-cost clocks and timing components are essential.

The NB2309AC1HDG is based on a sophisticated Digital Clock Manager (DCM) architecture. This allows the device to generate a variety of programmable clock signals, using only a single reference clock. The DCM core includes a built-in phase-locked loop (PLL) that allows it to produce multiple synchronized output clocks from a single reference clock.

It also incorporates a wide range of features and options for controlling output parameters, including output drive strength, pull-up/pull-down control, spread-spectrum clocking, delayed clock switching, and skew compensation. This makes it easy to customize the outputs according to the specific application requirements.

The NB2309AC1HDG offers up to eight output channels with frequencies of up to 250MHz. Output frequencies are adjustable with a single reference clock, making it much easier to synchronize multiple clocks. Furthermore, the device utilizes advanced jitter cancelling technologies, including spread spectrum clocking (SSC), phase-locked loop jitter attenuation (PJAT), and delay-locked loop jitter attenuation (DLJAT). This ensures low-phase jitter and high signal integrity over a wide range of frequencies.

An additional advantage offered by the NB2309AC1HDG is its small, ultra-compact package. This makes it a great fit for space-constrained applications, such as DSPs and FPGAs, and helps to reduce cost. Additionally, users can still utilize the full range of features offered by the device, thanks to its advanced clock management capabilities.

In short, the NB2309AC1HDG is an ideal choice for applications that require reliable, low-jitter, and cost-effective clocking and timing solutions. It combines the flexibility of multiple clock generators, PLLs, and frequency synthesizers into one compact and low-cost package, allowing users to optimize their application’s performance without sacrificing space or cost.
