TDA7200中文资料接收器数据手册Infineon规格书

描述 Description

The IC is a very low power consumption single chip FSK/ASK Superheterodyne Receiver (SHR) for the frequency band 400 to 440 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 synthesiser, a crystal oscillator, a limiter with RSSI generator, a PLL FSK demodulator, a data filter, an advanced data comparator (slicer) with selection between two threshold modes and a peak detector. Additionally there is a power down feature to save current and extend battery life, and two selectable alternatives of generating the data slicer threshold.

特性 Features

• Low supply current (Is = 5.7 mA typ. in FSK mode, Is = 5.6 mA typ. in ASK mode)

• Supply voltage range 5V ±10%

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

• FSK and ASK demodulation capability

• Fully integrated VCO and PLL Synthesiser

• ASK sensitivity better than -106 dBm over specified temperature range (- 20 to +70°C)

• FSK sensitivity better than -100 dBm over specified temperature range (- 20 to +70°C)

• Limiter with RSSI generation, operating at 10.7MHz

• 2nd order low pass data filter with external capacitors

• Data slicer with self-adjusting threshold
