NB2869ASNR2

Overview

The NB2869ASNR2 is a low-power clock synthesizer designed for reducing electromagnetic interference (EMI) in digital systems. It operates within a supply voltage range of 2.375V to 3.6V and supports output frequencies up to 13 MHz. The device integrates a phase-locked loop (PLL) to generate stable CMOS-level signals from an input reference. Packaged in a compact SOT-23-6 Thin or TSOT-23-6 format, it is optimized for space-constrained applications requiring precise clock generation with minimal power consumption.

Procurement Notes

Verify the specific suffix 'A' and package type against the manufacturer's latest datasheet to ensure compatibility with design requirements. Confirm that the operating voltage range aligns with the system's power rails. Check for any updated revision notes regarding electrical characteristics or thermal performance before finalizing procurement specifications.

Selection Notes

Select this component when a small form factor is required alongside low EMI performance. Ensure the input reference frequency matches the device's operational capabilities. Consider the 13 MHz maximum output limit when designing signal integrity paths. Verify that the CMOS output drive strength meets the load requirements of the downstream circuitry without additional buffering.
