Si4844-B20-GU数据手册RF/IF射频/中频RFID的射频接收器规格书PDF

描述 Description

Si4844-B20-GU4 devices are the first analog-tuned digital-display CMOS AM/FM/SW radio receiver ICs that integrate the complete receiver function from antenna input to audio output. Working with a host microcontroller (MCU) compatible 2-wire control interface, frequencies and stereo/mono information can be displayed on an LCD, while the analog-tune features are kept intact.  Built on our patented digital low intermediate frequency (low-IF) receiver architecture, Si4844-B20-GU ICs deliver superior RF performance and interference rejection. The integrated superior control algorithm provides an easy and reliable control interface while eliminating all of the manual tuned external components used in a traditional solution. For consumer applications requiring EN 55020 compliance, use Si4840/44 devices.
