Introduction

The BH1417F is an FM stereo transmitter IC with a simple configuration. This IC consists of a stereo modulator for generating a stereo composite signal and an FM transmitter for broadcasting FM signals over the air. The stereo modulator generates a composite signal comprising a main signal, sub signal, and pilot signal from a 38kHz oscillator. The FM transmitter radiates FM waves over the air by modulating a carrier signal with the composite signal. The frequency is configured for the North American region.

Features

• Improved sound quality via pre-emphasis, limiter, and low-pass filter circuits.
• Built-in pilot tone system FM stereo modulator circuit.
• Stable transmission frequency due to PLL-based FM transmitter circuit.
• PLL controlled via parallel data input (4-bit, 14 channels for North America).
• Γ (overline) derating: 4.5mW/°C for operation above Ta = 25°C.

Applications

• Wireless speakers
• PC sound cards
• Gaming consoles
• CD changers
• In-vehicle televisions
