It is intended to use the antenna system of the larger product and can get power and communication from an external source. 1.2 Purpose The purpose of this document is to provide a guideline for product designers when integrating the 21-999765-01 RFID Module. 1.3 Part Number Part Number SKU 21-199765-01 US/Canada RFID Module 1.4 Key Features  The 21-199765-01 RFID module will provide real time tag reading/processing for EPC Class 1 Gen2 compliant tags.  The communication interface is 10/100 baseT Ethernet  The Power interface is either Power over Ethernet iaw 802.3af/at or 24V DC Power Adapter  Up to 1W TX power over each of the 8 Coaxial contacts(only one at a time)  Heat sink and vented Metal enclosure for RF shielding and thermal control with convection cooling (no additional heat sink required).  Custom housing for slide on bracket mounting. 2 Architecture 2.1 System Architecture The Architecture of the 21-199765-01 is based on the Zebra Next Generation Engine RFID reader. The reader contains a Transmitter section, Receiver section, Synthesizer section, a Digital Modem, and a Host Interface section. The Transmitter section contains a digital-to-analog converter (DAC), I-Q modulator, filtering, RF power amplifier and the antenna multiplexer circuit. Communication with RFID tags is

The modulated signal sends data to the tag. The tag decodes this signal and then Backscatters (uplinks) its data during the CW portion of the cycle. The Transmitter (downlink) modulation used for communication with RFID tags is Double Sideband Amplitude Shift Keying (DSB-ASK) or Phase Reversal Amplitude Shift Keying (PR-ASK), depending on tag type and reader operating mode. Data rates range from 40 to 160 kbps. The Receiver section contains I-Q demodulator, filtering and an analog-to-digital (ADC) converter. The Receiver architecture is direct conversion, and therefore it operates using the same Local Oscillator (LO) frequency and RF channel used by the Transmitter. During the Backscatter (uplink) portion of the tag communication cycle the Receiver down-converts the modulation data from the tag to baseband, where it is amplified and low pass filtered before being converted to a digital signal by the ADC converter. The receiver accommodates tag Backscatter data rates range from 32 to 640 kbps, depending on tag type and reader operating mode. The Synthesizer section contains a voltage-controlled oscillator (VCO) and phase-locked loop. The Synthesizer generates a Local Oscillator (LO) signal that is shared with the Transmitter and Receiver sections. The VCO operating frequency is constrained under software control to the 902 to 928 MHz UHF ISM band when configured for the FCC region. The Digital Modem includes the DSP, dual-function ADC-DAC converter, and general purpose input/output communication interfaces. The Digital Modem has direct control over transceiver functions, including operating frequency, TX power control, and generation and decoding of baseband digital modulation data sent and received by the reader for RFID tag read and write operations. The Host interface section includes a microprocessor, its associated memory, and all of the circuitry needed to implement the Ethernet interface. The host processor serves as the interface between the radio and the outside world.
