Rochester Electronics Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers NBC12439AMNG

The NBC12439AMNG is a programmable PLL synthesized clock generator designed for general-purpose applications. It operates within a frequency range of 50 MHz to 800 MHz, with a voltage-controlled oscillator (VCO) frequency range of 400 MHz to 800 MHz. The device features programmable output frequencies with division ratios of 1, 2, 4, or 8, allowing for output frequency steps of 16 MHz, 8 MHz, 4 MHz, or 2 MHz, depending on the selected divider settings. This clock generator includes a fully integrated phase-lock loop (PLL) with an internal loop filter, eliminating the need for external components. It supports both parallel and serial programming interfaces for configuration, and offers best-in-class output jitter performance of ¬±20 ps peak-to-peak. The device is compatible with CMOS and TTL control inputs and operates over a supply voltage range of 3.135 V to 5.25 V. It is also RoHS compliant and operates within an ambient temperature range of -40¬8C to 85¬8C. The NBC12439AMNG is packaged in a QFN-32 form factor, making it suitable for compact designs.
