• Manufacturer Part Number: UAA3220
• Description: Frequency Shift Keying FSK/Amplitude Shift Keying ASK receiver
• Manufacturer: PHILIPS [NXP Semiconductors]

Philips Semiconductors
Notes
1. 100% AM modulation (ASK); available power from generator into a 50
2. With external matching network, to transform the impedance to 50
3.
4. Measured at the RF input connector of the test board into a 50
5. The data frequency range can be varied by changing C30 to C32 (see Figs 9 and 10) to match other bit rates.
6. t
7. The given turn-on time is only valid during strobing by pin PWD; if the IC is strobed on and off by the supply voltage
8. LC tank circuit (L60, C60) tuned to maximum phase slope.
