Product data sheet COMPANY PUBLIC Rev. 3.1 — 6 September 2012 227531 103 of 118 NXP Semiconductors MFRC630 Contactless reader IC 14. Application information A typical application diagram using a complementary antenna connection to the MFRC630 is shown in Figure 31. The antenna tuning and RF part matching is described in the application note Ref. 1 and Ref. 2. 14.1 Antenna design description The matching circuit for the antenna consists of an EMC low pass filter (L0 and C0), a matching circuitry (C1 and C2), and a receiving circuits (R1 = R3, R2 = R4, C3 = C5 and C4 = C6;), and the antenna itself. The receiving circuit component values needs to be designed for operation with the MFRC630. A reuse of dedicated antenna designs done for other products without adaptation of component values will result in degraded performance. For a more detailed information about designing and tuning the antenna, please refer to the relevant application notes: • MICORE reader IC family; Directly Matched Antenna Design, Ref. 1 and • MIFARE (14443A) 13.56 MHz RFID Proximity Antennas, Ref. 2. 14.1.1 EMC low pass filter The MIFARE system operates at a frequency of 13.56 MHz. This frequency is derived from a quartz oscillator to clock the MFRC630 and is also the basis for driving the antenna with the 13.56 MHz energy carrier. This will not only cause emitted power at 13.56 MHz Fig 31.
