1 Product Description
TDA7210V
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
