- Overview: The PA1418 is a Radio Transmitter that can send audio signals from personal computers, game consoles or independent devices to any type of audio equipment with a built in FM receiver. The IC consists of a Pre-Emphasis circuit that improves Signal to Noise Ratio (S/N), a Limiter circuit that prevents over-modulation and a low Pass filter (LPF) circuit that limits the maximum modulation frequency. The Stereo modulation circuit generates stereo composite signals through a FM transmitter circuit with PhaseLocked Loop (PLL) frequency synthesizers. 1.
