5 / 44 page TDA7210V Product Description Data Sheet 5 Revision 1.1, 2010-06-18 1 Product Description 1.1 Overview The IC is a very low power consumption single chip FSK/ASK Superheterodyne Receiver (SHR) for the frequency bands 810 to 870 MHz and 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, a data comparator (slicer) and a peak detector. Additionally there is a power down feature to save battery life. 1.2 Features Main features: • Selectable frequency ranges 810-870 MHz and 400-440 MHz • Low supply current (at 434 MHz Is = 5.7 mA typ. FSK mode, 5.0 mA typ. ASK mode) • Power down mode with very low supply current (50 nA typ.) • FSK and ASK demodulation capability • RF input sensitivity ASK/FSK typ. –115 dBm/–112 dBm @ 1 kbit/s RF=434 MHz • RF input sensitivity ASK/FSK typ. –111 dBm/–111 dBm @ 1 kbit/s RF=868 MHz • Fully integrated VCO and PLL Synthesiser • Limiter with RSSI generation, operating at 10.7 MHz • Selectable reference frequency • 2nd order low pass data filter with external capacitors • Data slicer with self-adjusting threshold • Supply voltage range 5 V ±10% 1.3 Application The TDA7210V is suitable for any kind of remote control system especially for low data rate wireless applications where low current consumption is important and where the line-of-sight limitation is driving the infra-red to RF replacement. Main applications: • Home automation - Lighting Control - Curtain, Roller Blind Control - Air Condition Control • Set-top-boxes • Garage Door Openers • Alarm Systems • Wireless Toys • Remote Keyless Entry Systems |
