描述 Description

The KT0810SG is KT Micro’s latest generation of high-quality Monolithic Digital FM Receiver designed to playback high-fidelity FM broadcasting signals.
The KT0810SG offers several new features on top of? the low BOM cost and high performance solution based on KT0810. Automatic short-antenna tuning enables the excellent signal reception with a short antenna, such as a short wire in package, and improves the user experience by eliminating the earphone antenna required by the competing products. With improved clock generation scheme, KT0810SG can work with any system clock generated by the controlling chip, no matter whether is a base-band, an AP or a MP3 decoder chip. The new SNR meter added another tool to validate a channel with existing RSSI. The programmable sound effects such as Bass Boosting ensure an uncompromised listening experience and suit a wide range of tastes. KT0810SG is packaged in QFN 3x3 making it ideal for any portable application. Extra signal swing at the audio output is provided to improve the flexibility for the following audio amplification.
KT0810SG operate with power supply ranging from 2.0V to 3.6V consuming merely 19mA in full operation mode and less than 10uA when standby – greatly extending the battery life. The KT0810SG works with I2C interfaces.
