AS3909 Product details

General Description
The AS3909/10 is a high performance 13.56MHz HF RFID Reader IC. The AS3909/10 is unequalled in the domain of HF Reader ICs; it contains two differential low impedance (1.5Ω) antenna drivers. These drivers are unmatched, which means that the IC can deliver up to 8 times the output power of a standard HF Reader IC using the same power supply voltage. Additionally using this configuration means half of the power consumption at the same output power. The IC has an operating voltage down to 2.4V and a low power operating mode of 5mA. This means the AS3909/10 is ideal for portable or battery powered applications.

Features
Close loop adjustment of ASK modulation for accurate control of modulation depth in case of ISO-14443B protocol
Low power (3.5μA) NFC target mode
AM/PM demodulator
Accurate RF envelope measurement (8 bit A/D)
High output power at 3.3V power supply:
   • Up to 700mW in case regulator is externally shorted
   • Up to 500mW in case differential output and antenna trimming is used
   • Up to 125mW in case of single ended output and antenna trimming is used
Squelch feature which performs gain reduction to compensate for noise generated by transponder processing
