CC2520 DATASHEET
2.4 GHZ IEEE 802.15.4/ZIGBEE® RF TRANSCEIVER
SWRS068 – DECEMBER 2007
3 Features
2394-2507MHz transceiver
• DSSS transceiver
• 250kbps data rate, 2 MChip/s chip rate
• O-QPSK with half sine pulse shaping modulation
• Very low current consumption
RX (receiving frame, -50 dBm): 18.5 mA
RX (waiting for frame): 22.3 mA
TX (+5 dBm output power): 33.6 mA
TX (0 dBm output power): 25.8 mA
• Three flexible power modes for reduced power consumption
• Low power fully static CMOS design
• Very good sensitivity (-98dBm)
• High adjacent channel rejection (49 dB)
• High alternate channel rejection (54 dB)
• On chip VCO, LNA, PA and filters.
• Low supply voltage (1.8 - 3.8 V)
• Programmable output power up to +5 dBm
• I/Q direct conversion transceiver
Small Size
• QFN 28 (RHD) package, 5 x 5 mm
• Very few external components
o minimized number of passives
o Only reference crystal needed
• Clock output for other ICs to limit the number of crystals needed in a system
• No external filters needed.
