CYBL11573-76FNXIT

Product Overview

CYBL11573-76FNXIT is an RF transceiver IC from Infineon Technologies. It provides transmit/receive RF functionality for the communication section of the end product. It is commonly selected for embedded wireless products, sensor networks, telemetry equipment and communication modules.

For design-in, continuation sourcing or repair work, engineers should review RF matching, antenna layout, interface timing, supply filtering and firmware compatibility. The selected orderable code should also be checked for package footprint, firmware or stack support, RF band, regulatory requirements and lifecycle status before approval.
