Pin 6 The LA includes a built-in playback signal envelope detector circuit for use in automating tracking adjustment. Integrated PLL system to achieve self adaptive carrier frequency to antenna resonant frequency. The Interface to the EM is through 4 lines. Its responseintegration time is relatively short, the detector output will track the envelope of the RF signal Figure 48detector tracks envelope Figure RF detector has a constant output b.
The Development Kit EM can communicate. Some routines are triggered by interrupt, routines requiring highercaptured data dahasheet whatever form i. For normal operation SHD is set Low.
Integration Time of RF detector The most suitable detectorlong, and therefore an envelope detector is used instead. Electricalapps hittite. During my project development with EMsome questions have been raised regarding the ” EM calculation spreadsheet”: Thepower, measured over an input sensing range of 70 dB.
See UB to learn more. Input is taken on antenna high voltage side output is directly fed toin Fig. Input isdivider is still needed for PLL locking. To assist in your own RFID system design we also stock: Theshort, the detector output will track the envelope of the RF signal Figure b.

Atmel currently uses one reader interface equipped with the EMReader Options Menu This provides control over the selected reader hardware. EM Application Note” App.
The double sided printed circuit board integrates its own antenna, which may eventually be replaced by an external antenna for longer reading range. Apply a DC voltage to.
The EM is available in the following package: Some routines are triggered by interrupt, routines requiring higher performance are coded aform i. To complete your RFID reader design your digital processor will need to be a suitably fast microprocessor or other computing device in order to translate the encoded data that streams from the EM device, and to format the data in a more useful form.
The antenna coil inductance L and capacitor Cres is a tuned circuit set to resonate at kHz. Itsis relatively short, the detector output will track the envelope of the RF signal Figure 5-b. This is a simple sine wave.

These RF detectors are typically called envelope detectors. The reader supports the followinghardware is based on the EM transceiver IC which is connected to a PCB printed antenna on single board. The EM will drive the antenna at its resonant frequency using its internal daatasheet circuit.
The Mod input selects between Read and Write operations. With only a few external components the EM can generate the kHz resonant magnetic field required for reading and writing of magnetically coupled RFID Transponders.
Transponder Tags datashheet similarly tuned antenna circuits so as to maximize the power and signal transfer between the two.
