Procurement Notes

Verify the specific ordering suffix against official STMicroelectronics documentation to confirm packaging details. The suffix indicates tape and reel packing. Confirm that the 0 to 70°C operating temperature range aligns with your system requirements. Ensure compatibility with the intended digital signal processor or modem chipset before procurement.

Selection Notes

Select this component for designs requiring a complete analog solution for ADSL CPE without external discrete filtering components. It is suitable for applications supporting Annex A, B, and C configurations. Verify interface compatibility with the host digital chip, such as the ST70138, to ensure proper integration into the Unicorn II chipset architecture.

Part Context

This part functions as the analog front-end within the STMicroelectronics Unicorn II chipset architecture. It pairs with the ST70138 digital transceiver to provide a complete ADSL USB modem solution. The design aims to reduce external bill-of-materials by integrating functions typically handled by discrete components.
