CM6320

Overview

The CM6320 is a 24-bump EMI filter with integrated ESD protection designed for data line applications. It utilizes a 5 x 5 CSP form factor with a 0.4 mm pitch. The device functions as a second-order low-pass RC (Pi) filter featuring 10 channels. Key electrical parameters include a resistance of 70 Ohms and capacitance of 30 pF per channel. The component is housed in a 24-UFBGA or WLCSP package.

Feature Summary

• Integrates EMI filtering and electrostatic discharge protection within a single compact component
• Provides multi-channel signal conditioning for high-density data interfaces
• Utilizes wafer-level chip-scale packaging to minimize board space

Applications

• Data line protection in portable electronic devices
• High-speed interface filtering for consumer electronics
• Signal integrity management in compact mobile hardware

Procurement Notes

Verify current availability status as the component may be classified as obsolete or end-of-life. Confirm that the specific package variant matches design requirements. Ensure compatibility with existing PCB footprints and soldering profiles. Check for authorized distributors offering remaining stock or qualified alternatives if direct procurement is unavailable.

Selection Notes

Select this component when simultaneous EMI suppression and ESD protection are required for multiple data lines in space-constrained designs. The 70 Ohm resistance and 30 pF capacitance values define the cutoff frequency characteristics. Consider the 0.4 mm pitch and 24-bump configuration for layout density constraints.

Part Context

This component belongs to onsemi's portfolio of passive and mixed-signal filters. It addresses the need for combined noise attenuation and transient protection in modern digital systems. The integration reduces bill-of-materials count by replacing separate filter and protection components.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify if newer generations from the manufacturer offer equivalent specifications or improved availability.
