CM1631-06DE

Overview

The CM1631-06DE is a six-channel EMI/RFI filter array from onsemi, designed for LCD and camera applications. It features a pi-style RC network configuration with component values of 15pF capacitance and 100 Ohm resistance per channel. The device integrates electrostatic discharge (ESD) protection capabilities alongside signal filtering. It operates within a cutoff frequency range of 110 MHz to 120 MHz, supporting data rates up to 48 Mbps. The component is housed in a compact 12-UFDFN exposed pad package, suitable for surface-mount assembly.

Feature Summary

• Integrates six independent pi-style RC filter channels with built-in ESD protection
• Provides high-frequency noise suppression for sensitive display and imaging interfaces
• Utilizes a compact surface-mount package design optimized for space-constrained PCB layouts

Applications

• LCD panel interface circuits
• Camera module signal lines
• Portable electronic devices requiring EMI mitigation

Procurement Notes

Verify the specific suffix DE against the official datasheet to confirm pinout and packaging details. Ensure compatibility with RoHS directives if required by your manufacturing standards. Cross-reference the 12-UFDFN footprint dimensions during PCB layout to guarantee proper soldering and thermal performance.

Selection Notes

Select this component when designing circuits that require simultaneous EMI filtering and ESD protection for multiple parallel data lines. The fixed 100 Ohm and 15pF values are optimized for low-speed digital signals like LVDS or MIPI. Consider the 120 MHz cutoff frequency to ensure it does not attenuate the desired signal bandwidth while effectively blocking higher-frequency interference.

Part Context

This part belongs to the CM1631 family of EMI filter arrays, which includes four-, six-, and eight-channel variants. The family shares similar internal architectures but differs in channel count and package size. The CM1631-06DE specifically addresses designs needing six filtered lines, bridging the gap between the four-channel and eight-channel options.

Replacement Considerations

Check for other members of the CM1631 series, such as the CM1631-04DE or CM1631-08DE, if channel count adjustments are permissible. Verify that any substitute maintains the same 100 Ohm/15pF RC values and 12-UFDFN package to ensure mechanical and electrical compatibility.
