.Data Sheet.co.kr High Performance Full Duplex FM Transceiver for Portable Devices __________________________ General Description __________________________ The QN8026 is a high performance, low power, fully integrated single-chip stereo full duplex FM transceiver designed for cell phones, PMP/PNDs, and portable radios. It integrates both FM receiving and transmitting functions, auto-seek and clear channel scan, and antenna tuning to ease matching in real applications. Advanced digital architecture enables superior receiver sensitivity, crystal clear audio. With its small footprint, minimal external ponent count and multiple clock frequency support, the QN8026 is easy to integrate into a variety of small form-factor low power portable applications. An integrated voltage regulator enables direct connection to a battery and provides high PSRR for superior noise suppression. A low-power Standby mode extends battery life. ESD protection is on all pins. The QN8026 is fabricated in highly reliable CMOS technology. _____________________________ Key Features - Worldwide FM Band Full Duplex Transceiver - 60 MHz ~ 108 MHz full band tuning in 50/100/200 k Hz step sizes - 50/75µs pre-emphasis and de-emphasis - High Performance FM Receiver (FMR) - Superior sensitivity: 1.2µVEMF - High SNR: 63d B Stereo - Ultra Low THD: 0.05% - High interference rejection - Integrated adaptive noise cancellation (SNC, HCC, SM) - Auto tuning support - Stereo Earphone Driving with Line in feature - In Line-in mode, audio input feed into earphone driver directly, save external earphone driver - 1 k Hz Tone Generator Inside - High Performance FM Transmitter (FMT) - 62d B Stereo SNR, 0.06% THD - Maximum 119 d BµV RF output level with 42d B adjustable range - Integrated Clear Channel Scan - Automatic Input Audio Sensing - RF power automatically turned off if no input audio signal for 60s - RDS/RBDS Transmit & Receive - Supports US and European data service,...
