TDA 7210V - ASK/FSK Receiver for the 434 and 868MHz Frequency Bands in a Tiny VQFN Package

TDA 7210V application example - RF receiver design is as small as a 1 euro cent coin!

More and more consumer products are shrinking and engineers are working hard to reduce PCB area and costs wherever possible.

With TDA 7210V, Infineon offers a variant of its popular TDA 7210 receiver in a VQFN package. This new device is targeted specifically at highly size-sensitive applications such as small set-top boxes and lighting control receivers which have to fit into a light bulb.

TDA 7210V is an ASK/FSK superheterodyne receiver for the 434 and 868MHz ISM bands. It is ideal for all industrial and consumer applications. The device is highly integrated and requires only a few external components. The low current consumption of only 5mA and a typical ASK sensitivity of -115dBm at a data rate of 1kbit/s are the key benefits of this IC.

ASK and FSK demodulation Frequency range: 400 to 440MHz, 810 to 870MHz ASK sensitivity typically -115dBm over full temperature range at 1kbit/s data rate FSK sensitivity typically -112dBm over full temperature range at 1kbit/s data rate Low supply current Very low supply current in power-down mode (50nA typ.) Data filter with external capacitors and integrated resistors (resulting in high flexibility with support for different data rates) Built-in AGC with user-presetable threshold for LNA low/high gain switch-over Temperature range -40 to +85°C 4.5 x 5.5 mm small VQFN-32 package Fully integrated PLL synthesizer and VCO (no need for external VCO coils) IF limiter with RSSI generation, centered on 10.7MHz
