13 / 244 page  CC2510Fx / CC2511Fx SWRS055G Page 13 of 236 6.2 RF Receive Section TA = 25°C, VDD = 3.0 V if nothing else stated. All measurement results are obtained using the CC2510EM reference design ([1]). Parameter Min Typ Max Unit Condition/Note Digital channel filter bandwidth 58 812 kHz User programmable (see Section 13.6). The bandwidth limits are proportional to crystal frequency (given values assume a 26.0 MHz crystal). 2.4 kBaud data rate, sensitivity optimized, MDMCFG2.DEM_DCFILT_OFF=0 (2-FSK, 1% packet error rate, 20 bytes packet length, 203 kHz digital channel filter bandwidth) Receiver sensitivity −103 dBm The RX current consumption can be reduced by approximately 2.4 mA by setting MDMCFG2.DEM_DCFILT_OFF=1. The typical sensitivity is then −101 dBm. The sensitivity can be improved to typically −105 dBm with MDMCFG2.DEM_DCFILT_OFF=0 by changing registers TEST2 and TEST1 (see Page 222). The temperature range is then from 0 oC to 85oC. Saturation −10 dBm Adjacent channel rejection 23 dB Desired channel 3 dB above the sensitivity limit. 250 kHz channel spacing Alternate channel rejection 32 dB Desired channel 3 dB above the sensitivity limit. 250 kHz channel spacing See Figure 55 for plot of selectivity versus frequency offset Blocking ±10 MHz offset ±20 MHz offset ±50 MHz offset 64 70 71 dB dB dB Wanted signal 3 dB above sensitivity level. Compliant with ETSI EN 300 440 class 2 receiver requirements. 10 kBaud data rate, sensitivity optimized, MDMCFG2.DEM_DCFILT_OFF=0 (2-FSK, 1% packet error rate, 20 bytes packet length, 232 kHz digital channel filter bandwidth) Receiver sensitivity −98 dBm The RX current consumption can be reduced by approximately 2.2 mA by setting MDMCFG2.DEM_DCFILT_OFF=1. The typical sensitivity is then −97 dBm. The sensitivity can be imp roved to typically −100 dBm with MDMCFG2.DEM_DCFILT_OFF=0 by changing registers TEST2 and TEST1 (see Page 222). The temperature range is then from 0 oC to 85oC. Saturation −9 dBm Adjacent channel rejection 19 dB Desired channel 3 dB above the sensitivity limit. 250 kHz channel spacing Alternate channel rejection 25 dB Desired channel 3 dB above the sensitivity limit. 250 kHz channel spacing See Figure 56 for plot of selectivity versus frequency offset Blocking ±10 MHz offset ±20 MHz offset ±50 MHz offset 59 65 66 dB dB dB Wanted signal 3 dB above sensitivity level. Compliant with ETSI EN 300 440 class 2 receiver requirements. CC2511F8 - Not Recommended for New Designs |
