TDA5230RF/IF射频/中频RFID的射频接收器规格书PDF中文资料

TDA5230属于RF/IF射频/中频RFID的射频接收器。由英飞凌科技股份公司制造生产的TDA5230射频接收器RF 接收器用于接收已调制的射频信号并对其进行解调，然后将数据传送到系统中进行处理。频率范围是 AM、FM、WB、0 Hz 至 64 GHz，数据速率为 250 bps 至 16 Gbps，数据接口包括连接器、I2C、I2S、引脚焊盘、并行、PCB、串行、焊盘、SPI、UART 和 USB。

Overview

The TDA523x is a family of universal, highly sensitive, low-power single-chip ASK/FSK superheterodyne image-reject-receivers for Manchester-coded data signals in the ISM bands between 302..320 MHz, 433..450 MHz and 865..870 MHz. The chips include fully-integrated digital baseband data processing and produce clean data output via SPI, thus significantly reducing the load on the host processor and standby power consumption. The TDA523x family of chips offers a high level of integration and needs only few external components for application deployment.
