IDS-R900G
UHF RFID Reader

EPC Class 1 Gen2 Compatible

Description:
The IDS-R900G UHF reader chip is a highly integrated analogue front end and data framing system for 900MHz RFID reader systems. Built in programming options make it suitable for a wide range of applications in UHF RFID systems, especially portable and embedded systems due to the low power consumption and simple BOM.
The reader configuration is achieved by selecting the desired settings in control registers. Direct access to all control registers also allows fine-tuning of different reader parameters if needed.
The IDS-R900G complies with EPC Class 1 Generation 2 protocol (ISO 18000-6C).
Key Features:
  • Supply voltage range 5.0 to 5.5V
  • Protocol: ISO 18000-6C / EPC Class 1 Gen2
  • Supports ISO18000-6A/B and proprietary protocols in direct mode
  • Antenna driver using OOK or PR-ASK modulation
  • Dual receiver input with automatic I/Q selection providing both AM and PM demodulation avoiding communication holes
  • Reception automatic gain control
  • 3.3V voltage regulator providing up to 20 mA for external MCU
  • On-chip power amplifier (20 dBm) for short range applications
  • Significant increase of PSRR through on-chip RF output supply regulator
  • Power-down, standby and active mode
  • Temperature range: -40°C to 110°C
  • Supports frequency hopping
  • Selectable clock output for MCU
Applications:
  • UHF RFID reader systems
  • Hand-held UHF RFID readers
