12. PN7462 family Contactless interface
The PN7462 family embeds a high power 13.56 RF front end. The RF interface
implements the RF functionality, like
antenna driving, and the receiver circuitry and all the
low-level functionalities, to enable the realization of an NFC forum
or an EMV compliant
reader.
The PN7462 family allows different voltages for the RF drivers. The PN7462
family uses an external oscillator, working at 27.12 MHz, as a clock source for generating
the RF field and its internal operation.
