Page 4: Introduction
23 mm Transponder Reference Manual 25 July 1996 1. Introduction The TIRIS 23 mm Glass Encapsulated Pulsed FM Transponder is a key product in low frequency RFID systems that can be used for a variety of applications, such as automotive security systems. The device is available in Read Only (RO) and Read/Write (R/W) versions. -
Page 5: Transponder Packaging
25 July 1996 23 mm Transponder Reference Manual 2. Transponder Packaging The dimensions of the transponder are given in Figure 3. The 23 mm shape offers several advantages: 1. The transponder is hermetically sealed. 2. The transponder is robustly constructed to withstand vibration (IEC68-2-6) and shock (IEC68-2-6). -
Page 6: Figure 4: Charge And Read Function Of The Transponder
23 mm Transponder Reference Manual 25 July 1996 The typical data low bit frequency is 134.2 kHz, the typical data high bit frequency is 123.2 kHz. The low and high bits have different durations, because each bit takes 16 RF cycles to transmit. The high bit has a typical duration of 130 µs, the low bit of 119 µs. -

Page 10: Reader And System Design Impact
23 mm Transponder Reference Manual 25 July 1996 5.2 Reader and System Design Impact * Ease of receiver and power function design and the optimization of performance due to sequential power/read functions. * Low field strength for transponder charge, resulting in lower cost of the power function. * Optional performance and cost trade-offs by variation of: interrogation speed by software down to 35 ms. -
Page 11: Emi/Emc Performance
25 July 1996 23 mm Transponder Reference Manual 6. EMI/EMC Performance 6.1 General For any given RF-ID system, the EMI/EMC performance is determined by three factors: 1. The reader design and the resulting noise immunity performance 2. The signal strength of the transponder and Signal/Noise ratio at the receiver input 3. -
