QN8007B/8007LB High Performance Digital FM Transmitter for Portable Devices ____________________________ General Description ________________________ The QN8007 is a high performance, low power, full-featured single-chip stereo FM transmitter designed for portable audio/video players, automotive accessories, cell phones, and GPS personal navigation devices. It integrates transmitting functions, clear channel scan, and antenna tuning to ease matching in real applications. Advanced digital architecture enables variable input gain programming; selectable pre-emphasis, precision low-spur MPX stereo encoding and pilot tone generation, low-noise PLL-based modulation, and an on-chip power amplifier with variable output level and RF band-pass filtering to ensure optimum transmit spectrum purity. With its small footprint, minimal external component count and multiple clock frequency support, the QN8007 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 QN8007 is fabricated in highly reliable CMOS technology. _____________________________ Key Features _____________________________  Worldwide FM Band Transmit • 76 MHz to 108 MHz full band tuning in 50/100/200 kHz step sizes • 50/75s pre-emphasis  High Performance FM Transmitter (FMT) • 66dB Stereo SNR, 0.03% THD • Maximum 121dBµV RF output level with 42dB adjustable range • Integrated Clear Channel Scan  RDS/RBDS Transmit • Supports US and European data service, including TMC (Traffic Messaging Channel) (not available in QN8007L)  Flexible Audio Interfaces • Digital audio interface supports I2S and a variety of PCM data formats with 4 different data rates • Programmable analog audio input/output • Integrated audio AGC and soft clipping  Very Low Power Consumption • 9.2 mA • Integrated voltage regulator, direct connect to battery • Power saving idle and standby modes • Low shutdown leakage current  Ease of Integration • Small footprint, 4 x 4 x 0.85mm QFN24 • Only 2 external passive components required • Adaptive antenna tuning • Low cellular and GPS band spurs • High Immunity to TDMA (GSM/GPRS) burst noise • Multiple crystal frequencies supported • 2-wire and 3-wire control interfaces  Robust Operation • -250C to +850C operation • ESD protection on all input and output pads _____________________________ Typical Applications __________________________  Cell Phones / PDAs / Smart Phones  Portable Audio & Media Players  GPS Personal Navigation Devices  Automotive and Accessories Rev 2.09 (11/09) Confidential A Copyright ©2009 by Quintic Corporation Confidential Information contained herein is covered under Non-Disclosure Agreement (NDA).
