8. Minimum application circuitry

The following figure shows a minimal application circuitry for the HTRC110. The reader

coil La together with the capacitor Ca forms a series resonant LC circuit (f = 125 kHz). The

high voltages in the LC circuit are divided to safe operating levels by Rv and the chip

internal resistor Rdem_in behind the RX-pin. The two capacitors connected to XTAL1 and

XTAL2 shall be the recommended values and types from the crystal's data sheet.

Alternatively to a crystal a ceramic resonator can be used or an external clock source can

be connected to XTAL1.
