SE2432L Pinout 24-Pin QFN JEDEC-J-STD-020) (Top View) Skyworks Green products are compliant with Description all applicable legislation and are halogen-free. The SE2432L is a high performance, fully integrated RF Front-End For additional information, refer to Skyworks Module (FEM) designed for ZigBee/Smart Energy applications. Denition of Green, document number SQ04-0074. The SE2432L is designed for ease of use and maximum flexibility. The device provides integrated and fully matched input baluns, an integrated inter-stage matching and harmonic filter, and digital controls compatible with 1.6 to 3.6 V CMOS levels. The RF blocks operate over a wide supply voltage range from 2.0 V to 3.6 V that allows the SE2432L to be used in battery powered applications over a wide spectrum of the battery discharge curve. The SE2432L is provided in a small, 24-pin, 3 x 4 mm Quad Flat No-Lead (QFN) package. The pin configuration and package are shown in Figure 1. A functional block diagram is shown in Figure 2. Signal pin assignments and functional pin descriptions are provided in Table 1. Skyworks Solutions, Inc.
