Telecom Procurement Notes

Verify the manufacturer designation as Microchip Technology, distinct from other vendors using similar numeric identifiers. Confirm the specific ordering suffix PQCT indicates the tape-and-reel packaging format with a standard reel quantity. Ensure the datasheet corresponds to the miSLIC product category rather than generic interface components.

Telecom Selection Notes

Select this component when a single-channel subscriber line interface with a 4-wire serial connection is required. Verify that the 3.3 V nominal supply voltage aligns with the system design constraints. Consider the 48-QFN package dimensions for PCB layout compatibility and ensure the thermal requirements fit within the specified 1.5 W power dissipation limit.
