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.
