Overview
Description
The SI4848DY-T1-E3 is a single-chip AM/FM/SW/LW radio receiver IC from Silicon Labs, designed for portable and consumer audio applications. It integrates a low-power DSP-based tuner with on-chip analog-to-digital conversion (ADC), eliminating the need for external IF components.
Key Features:
- Frequency Range: AM (520–1710 kHz), FM (64–108 MHz), SW (2.3–30 MHz), LW (153–279 kHz).
- Digital Tuning: I²C control interface for channel selection and volume adjustment.
- Low Power: Operates at 2.7–5.5V, suitable for battery-powered devices.
- Minimal External Components: Requires only a few passive parts, reducing BOM cost.
- Audio Output: Supports both analog (headphone) and digital (I²S) outputs.
Applications: Portable radios, clock radios, and multimedia devices.
This IC simplifies radio receiver design while offering high sensitivity and low power consumption.
