TDA5200数据手册RF/IF射频/中频RFID的射频接收器规格书PDF

描述 Description

The IC is a very low power consumption single chip ASK Single Conversion Receiver for receive frequencies bands 868-870 MHz and 433-435 MHz. The IC offers a high level of integration and needs only a few external components. The device contains a low noise amplifier (LNA), a double balanced mixer, a fully integrated VCO, a PLL synthesizer, a crystal oscillator, a limiter with RSSI generator, a data filter, a data comparator (slicer) and a peak detector. Additionally there is a power down feature to save battery life.

特性 Features

• Low supply current (I s = 4.8 mA typ. at 868 MHz, I s = 4.6 mA typ. at 434 MHz)

• Supply voltage range 5 V ±10 %

• Power down mode with very low supply current (50 nA typ)

• Fully integrated VCO and PLL Synthesizer

• RF input sensitivity < – 107 dBm

• Selectable frequency ranges around 868-870 MHz and 433-435 MHz

• Selectable reference frequency
