Detailed Description for SI4322-A0-FT
Product Overview
SI4322-A0-FT from Silicon Labs is a EZRadio FSK/OOK receiver IC. This RF receiver description summarizes the receiver function, operating band, modulation or broadcast standard, interface considerations and sourcing relevance for engineering teams.
The content is written for BOM review and procurement use, focusing on practical receiver parameters rather than internal stock notes.
Key Features
- Manufacturer: Silicon Labs
- Part Number: SI4322-A0-FT
- Device Type: EZRadio FSK/OOK receiver IC
- Receiver Architecture: Low-power EZRadio receiver family for ISM-band RF data links
- Frequency Bands: Family options for common 315 MHz, 433 MHz, 868 MHz and 915 MHz bands
- Modulation: FSK and OOK receive support depending on configuration
- Interface: Serial configuration interface plus digital data output to the host MCU
- Receiver Functions: RSSI, programmable channel/filter settings and data-slicer support in family architecture
- System Role: Compact receiver IC for one-way RF control and telemetry
- Package / Case: Manufacturer package code from ordering suffix; check mechanical drawing before PCB release
- Design Notes: Confirm the exact center-frequency version and reference crystal because Si432x/Si4330 ordering codes are band-specific.
Applications
ISM-band receiver modules, RKE/remotes, sensors, alarms and industrial low-data-rate receive channels.
Redesign or spare builds for older Silicon Labs EZRadio receiver platforms where exact variant matching is needed.
Quality & Sourcing
Antrex Electronics can support sourcing for SI4322-A0-FT through available stock checks, BOM consolidation and alternative-lot review. For RF receiver components, packaging condition, date code, MSL handling and original labeling should be verified before shipment.
For project builds, repair support or shortage coverage, Antrex Electronics can coordinate visual inspection, package verification and third-party testing when required. This helps buyers manage risk when sourcing discontinued, legacy or hard-to-find RF receiver parts.
