Telecom Procurement Notes

Verify the manufacturer designation, as the component is associated with both Lantiq and Infineon Technologies. Confirm the specific package variant, such as PG-DSO-24 or P-DSO-24-8, matches the design requirements. Ensure the operating temperature range of -40°C to 85°C is suitable for the intended environment. Check for any ordering suffixes that may indicate specific binning or testing criteria.

Telecom Selection Notes

Select this component for applications requiring a single-channel SLIC with high gain and robust power handling. The integrated SICOFI and FlexiSLIC capabilities simplify circuit design for digital loop carriers. Consider the 24-SOIC package size for PCB layout constraints. Verify compatibility with the required supply voltage rails, specifically the negative voltages needed for line powering.

Telecom Part Context

This part belongs to the PBL 38640 series, which combines SICOFI and FlexiSLIC technologies. It is a bipolar integrated circuit intended for telecom interfaces. The series includes variants like the PBL38640/2SHA. The component is widely used in modern telecommunication infrastructure for connecting subscriber lines to digital networks.

Telecom Replacement Considerations

The PBL38640/2SHA is a documented alternative within the same product family. Both parts share similar functional characteristics but differ in packaging. Verify pinout compatibility and thermal performance when substituting between SOIC and SSOP packages.
