Texas Instruments's NA556N represents the next generation of programmable timing solutions in our Integrated Circuits catalog. This sophisticated clock IC delivers unparalleled timing accuracy with programmable output skew, slew rate control, and fail-safe input monitoring. The device supports frequency margining and offers multi-voltage operation (1.8V to 3.3V) for design flexibility. As part of the Clock/Timing category, it's specifically designed for applications demanding ultra-low jitter (<1ps RMS) and high frequency stability. Perfect for 400G Ethernet switches, optical transceivers, AI accelerator cards, and autonomous vehicle systems. The NA556N is also widely used in data center timing architectures, military communications, and high-speed digital design where synchronization precision is paramount.
