NB2760ASNR2

Overview

The NB2760ASNR2G is a low power, reduced EMI clock synthesizer manufactured by onsemi. It functions as a spread spectrum frequency modulator designed to lower electromagnetic interference at the clock source. The device operates with a 3.3 V or 2.5 V supply and features an integrated loop filter. Key electrical specifications include a maximum cycle-to-cycle jitter of 200 ps, an output duty cycle of 45/55%, and a frequency deviation of ±0.65% at 8 MHz. It generates a 1X low EMI spread spectrum clock from an input frequency range of 6.0 MHz to 12 MHz (at 2.5 V) or 6.0 MHz to 13 MHz (at 3.3 V).

Feature Summary

• Generates an EMI optimized clocking signal using a proprietary all-digital modulation profile.
• Operates with a 3.3 V / 2.5 V supply with operating current less than 4.0 mA.
• Integrated loop filter components reduce external component count.
• Available in a TSOP-6 (TSOT-23-6) package.

Applications

• Portable devices such as MP3 players.
• Digital still cameras.
• Systems requiring significant system-wide EMI reduction.

Procurement Notes

Verify the specific ordering suffix for lead-free compliance. The NB2760ASNR2G indicates a Pb-Free package, whereas the base NB2760ASNR2 may not be. Confirm availability status directly with the manufacturer or authorized distributors, as standard stock levels vary. Ensure the required temperature range of 0°C to 70°C aligns with the target application environment.

Selection Notes

Select this component when reducing EMI without adding external ferrite beads or shielding is required. Ensure the input clock frequency falls within the 6.0 MHz to 12 MHz range for 2.5 V operation or 6.0 MHz to 13 MHz for 3.3 V operation. Verify that the power-down control pin (PD) is managed correctly to enable or disable the device as needed for the system design.

Part Context

The NB2760A belongs to onsemi's family of low power clock synthesizers. The 'SNR2' suffix denotes the TSOP-6 (TSOT-23-6) surface mount package with tape and reel shipping quantities of 2500 units. The 'G' suffix specifically identifies the lead-free version of the component.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult onsemi technical support for direct replacements or cross-references if the NB2760ASNR2G is unavailable.
